TI - Slanted Beam Extraction on Laser Ion Source J2 - Proc. of IPAC2022, Bangkok, Thailand, 12-17 June 2022 CY - Bangkok, Thailand T2 - International Particle Accelerator Conference T3 - 13 LA - english AB - Laser ion sources generate plasma and supply ions by focusing energy by light onto a solid surface. The ionization is achieved during the pulsed laser irradiation period. Then the plasma expands vertically from the target surface as it moves forward. Usually, this drift distance is chosen from tens of centimeters to several meters. Once the required pulse width and plasma density are met, an extraction electric field is applied. In most cases, this electric field is set in the same direction as the direction of the plasma. In this study, we experimentally verify how performance is achieved when the direction of the extraction field is at an angle to the direction of motion of the plasma. If the extraction field can be slanted without degradation of the ion source performance, it is considered to be able to shield neutral vapors and debris generated simultaneously with the plasma, which will be advantageous for the long-term operation of the laser ion source.
