TUIZGD2	RIKEN Accelerator-Driven Compact Neutron Systems, RANS Project and Their Capabilities
	Y. Otake RIKEN, Center for Advanced Photonics, Wako, Japan
	RIKEN Accelerator-driven compact neutron source, RANS, has been operational since 2013. There are two major goals of RANS research and development. One is to establish a new compact low energy neutron non-destructive evaluation system on-site of floor-standing type for industrial use. Another goal is to invent a novel transportable compact neutron system for the preventive maintenance of large scale construction such as a bridge. The low energy transmission imaging, neutron diffractometer, small angle scattering instruments, fast neutron transmission imaging, fast neutron back scattering imaging, neutron induced prompt gamma-ray analysis and neutron activation analysis are available with RANS. For further compact neutron system, RANS-II with 2.49 MeV proton linac starts in operation and fast neutron scattering imaging experiments for non-destructive visualization of concrete degradation, and the suspension bridge cables are being successfully realized. Based on more compact and light proton accelerator tube and the solid state amplifier with 500 MHz, RANS-III development starts towards a transportable neutron system. The proton energy and the neutron generating target of RANS-III is the same as RANS-II, so that all the novel technologies of fast neutron non-destructive test to be demonstrated for practical use in RANS-II will be available in RANS-III.

TUOZGD1	Need for Portable Accelerators in Cultural Heritage	808
	T.K. Charles The University of Liverpool, Liverpool, United Kingdom R.M. Bodenstein, A. Castilla JLab, Newport News, Virginia, USA
	Ion Beam Accelerators (IBA) centres have provided researchers with powerful techniques to analyse objects of cultural significance in a non-destructive and non-invasive manner. However, in some cases it is not feasible to remove an object from the field or museum and transport it to the laboratory. In this contributed talk, we present as a manner of a short review, examples of the benefits provided from these techniques in the study of material culture and discuss the initial steps to consider when investigating the feasibility of a compact accelerator that can be taken to sites of cultural significance for PIXE analysis. In particular, we consider the application of a compact, robust 2 MeV proton accelerator that can be taken into the field to perform PIXE measurements on rock art. We detail the main challenges and considerations for such a device.

	The high-brightness electron beam at the Photo Injector Test facility at DESY in Zeuthen (PITZ) is being prepared for use in dosimetry experiments and for the study of biological effects in thin samples. This is part of the preparations for FLASHlab@PITZ which is going to be an R&D platform for FLASH and VHEE radiation therapy and radiation biology. These studies require precise information on the electron beam parameters downstream of the exit window, such as the scattering angle and the energy spectrum of the particles as well as the thermal load on the exit window. A Titanium window is compared with a DESY Graphite window design. Heat deposition in the window by a single 22MeV / 1nC electron bunch of various size, its scattering and energy spectrum due to passage through the window are calculated by means of the Monte Carlo program FLUKA. Time resolved temperature profiles, as generated by the passage of 1ms long electron pulse trains with up to 4500 single pulses, each of them between 0.1 and 60ps long, are calculated with a self-written FEM code.

	Neutron sources are of great utility for various applications, especially in the fields of nuclear medicine, nuclear energy and imaging. At SAMEER, we have designed a linear electron accelerator based neutron source via photo-neutron generation. The accelerator is a 15 MeV linac with both photon and electron mode and is capable of delivering high beam current to achieve beam power of 1 to 2 kW. Efforts are in place to achieve further higher beam powers. 15 MeV electrons are incident on a bremsstrahlung target followed by a secondary target to achieve neutrons. To further optimize and enhance the neutron yield, backing material is provided. In this paper, we present the simulation of (e, g) and (g, n) processes using the Monte Carlo code FLUKA. The optimization of Tungsten as the convertor target whereas of the Beryllium as the neutron target is discussed in detail. We have explored various backing materials in order to optimize the total neutron yield as well as the thermal neutron yield. The simulation results have been considered for the finalisation of all material parameters for the set-up of this neutron source activity.

	The SOCHI (Station of CHip Irradiation) station was constructed at the NICA accelerator complex for single event effect testing of decapsulated microchips with low-energy ion beams (3.2 MeV/n). The peculiarity of microchip radiation tests in SOCHI is connected with the pulse beam operation of the heavy ion linear accelerator (HILAc) and a restriction on the pulse dose on the target. The SOCHI station construction, the equipment and the results of the first beam runs are discussed.

	Interstellar complex molecules can be found in molecular clouds which are spread throughout our galaxy. Some of these molecules are thought to be the precursors of bio-molecules. Therefore, understanding the formation processes of those interstellar complex molecules is crucial to understanding the origin of the building blocks of life. There are currently more than a hundred known complex molecules discovered in interstellar clouds. However, the formation processes of those molecules are not yet well understood since they occur in very extreme conditions and very short time scale. Ultrafast spectroscopy can be applied to study those processes that occur in the time scale of femtoseconds or picoseconds. In this work, we present an overview of the applications of MIR and THz pump-probe experiments in astrochemistry studies. An experimental setup to simulate space conditions that mimic the environments where the interstellar complex molecules are formed is currently being developed at the PBP-CMU Electron Linac Laboratory. Then, we present our development plan of the experimental station and its current status.

THPOMS057	Using Co-Moving Collisions in a Gear-Changing System to Measure Fusion Cross-Sections	3105
	E.A. Nissen JLab, Newport News, Virginia, USA
	Funding: Notice: Authored by Jefferson Science Associates, LLC under U.S. DOE Contract No. DE-AC05-06OR23177. The U.S. Government retains a license to publish or reproduce this manuscript. In this work we look at a possible use for a system that collides beams moving in the same direction using a gear-changing synchronization method as a means of measuring low energy phenomena, such as fusion cross sections. Depending on the energies used this process will allow for interactions for any desired charge state of the target nuclei. Earlier concepts for low energy interactions to study focused on beams crossing at an angle to give the low energy interactions, as well as general investigations of comoving collisions. This proposal would use gear-changing, a method involving two different harmonic numbers of bunches in each collider ring, to have the same types of collisions, with a luminosity equal that of a head-on machine. In this work we detail the design considerations for such a machine, leveraging experimental experience with a co-moving, gear-changing system.

THPOMS060	Development of Analytical Light Source for Construction of Femtosecond Pulse Radiolysis System Using Er Fiber Laser	3109
	Y. Kaneko, Y. Koshiba, K. Sakaue, M. Sato, M. Washio Waseda University, Tokyo, Japan K. Sakaue The University of Tokyo, Graduate School of Engineering, Bunkyo, Japan
	We are trying to elucidate the initial process of radiation chemical reactions, which is considered to be an unknown area. One of the methods to elucidate this initial process is pulse radiolysis. In pulse radiolysis, a substance is irradiated with ionizing radiation and at the same time irradiated with analytical light, and the absorption spectrum of the light can be traced back in time to the active species. However, the radiation chemical reaction starts in a very short time, and the pulse radiolysis system needs to have the same time resolution. Therefore, the analytical light should be ultra-short pulses. In addition, the absorption wavelength of the substance is not always known. Hence, the wavelength range of the analytical light should be broad. Since the absorption wavelengths of important active species are in the visible light region, it is desirable to cover the visible light region as well. We believe that supercontinuum light generated from the second harmonic of the Er fiber laser is the best analytical light to meet these requirements. In this presentation, we describe the current status of the development of the supercontinuum light generation and future prospects.

A proton beam irradiation system for space part test has been developed at Korea Multi-purpose Accelerator Complex (KOMAC) based on 100 MeV proton linac. It consists of a thermal vacuum chamber, a beam diagnostic system and a control system in the low flux beam target room. The thermal vacuum chamber accommodates the capacity for proton beam irradiation in addition to temperature control in vacuum condition. The beam diagnostic system is newly installed to measure the lower dose rate than existing one. In this paper, the proton beam irradiation system for space part test including a thermal vacuum chamber, newly installed beam diagnostic system is presented.

The SOCHI (Station of CHip Irradiation) station was constructed at the NICA accelerator complex for single event effect testing of decapsulated microchips with low-energy ion beams (3.2 MeV/n). The peculiarity of microchip radiation tests in SOCHI is connected with the pulse beam operation of the heavy ion linear accelerator (HILAc) and a restriction on the pulse dose on the target. The SOCHI station construction, the equipment and the results of the first beam runs are discussed.

Interstellar complex molecules can be found in molecular clouds which are spread throughout our galaxy. Some of these molecules are thought to be the precursors of bio-molecules. Therefore, understanding the formation processes of those interstellar complex molecules is crucial to understanding the origin of the building blocks of life. There are currently more than a hundred known complex molecules discovered in interstellar clouds. However, the formation processes of those molecules are not yet well understood since they occur in very extreme conditions and very short time scale. Ultrafast spectroscopy can be applied to study those processes that occur in the time scale of femtoseconds or picoseconds. In this work, we present an overview of the applications of MIR and THz pump-probe experiments in astrochemistry studies. An experimental setup to simulate space conditions that mimic the environments where the interstellar complex molecules are formed is currently being developed at the PBP-CMU Electron Linac Laboratory. Then, we present our development plan of the experimental station and its current status.

In this work we look at a possible use for a system that collides beams moving in the same direction using a gear-changing synchronization method as a means of measuring low energy phenomena, such as fusion cross sections. Depending on the energies used this process will allow for interactions for any desired charge state of the target nuclei. Earlier concepts for low energy interactions to study focused on beams crossing at an angle to give the low energy interactions, as well as general investigations of comoving collisions. This proposal would use gear-changing, a method involving two different harmonic numbers of bunches in each collider ring, to have the same types of collisions, with a luminosity equal that of a head-on machine. In this work we detail the design considerations for such a machine, leveraging experimental experience with a co-moving, gear-changing system.

We are trying to elucidate the initial process of radiation chemical reactions, which is considered to be an unknown area. One of the methods to elucidate this initial process is pulse radiolysis. In pulse radiolysis, a substance is irradiated with ionizing radiation and at the same time irradiated with analytical light, and the absorption spectrum of the light can be traced back in time to the active species. However, the radiation chemical reaction starts in a very short time, and the pulse radiolysis system needs to have the same time resolution. Therefore, the analytical light should be ultra-short pulses. In addition, the absorption wavelength of the substance is not always known. Hence, the wavelength range of the analytical light should be broad. Since the absorption wavelengths of important active species are in the visible light region, it is desirable to cover the visible light region as well. We believe that supercontinuum light generated from the second harmonic of the Er fiber laser is the best analytical light to meet these requirements. In this presentation, we describe the current status of the development of the supercontinuum light generation and future prospects.
