	In order to study the remaining open questions concerning CP violation and neutrino mass hierarchy, as well as to search for physics beyond the Standard Model, future experiments require precise measurements of the neutrino interaction cross-sections in the GeV/c regime. The absence of a precise knowledge of the neutrino flux currently limits this measurement to a 10-20% uncertainty level. The ENUBET project is proposing a novel facility, capable of constraining the neutrino flux normalization through the precise monitoring of kaon decay products in an instrumented decay tunnel. The collaboration has conducted numerous studies using a beam-line with a central Kaon momentum of 8.5 GeV/c and a ±10% momentum spread. We present here the design of a new beam-line, broadening the range of Kaons to include momenta of 4, 6, and 8.5 GeV/c, thus allowing ENUBET to explore cross-sections over a much larger energy range. In this contribution, we discuss the status of this design, the optimization studies performed, the early results, and the expected performance in terms of kaon and neutrino rates. We also present the first estimations of the background expected to be seen by the experiment.

THPOTK058	CERN’s East Experimental Area: A New Modern Physics Facility	experiment, target, MMI, operation	2911

	CERN’s East Area has hosted a variety of fixed-target experiments since the 1950s, using four beamlines from the Proton Synchrotron (PS). Over the past 4 years, the experimental area - CERN’s second largest - has undergone a complete makeover. New instrumentation and beamline configuration have improved the precision of data collection, and new magnets and power convertors have drastically reduced the area’s energy consumption. This article will summarize the major challenges encountered for the design of the renovated beamlines and for the preparation and test of the components. The infrastructure was carefully fitted resulting in a very smooth beam commissioning, the details of which will also be presented along with the restart of physics in the second half of 2021. With the return of the beams in the accelerator complex, the East Area’s experiments have taken physics measurements again and the facility’s central role in the modern physics landscape has been restored.
