Beam generation with the 4-MV RLA injector and acceleration through the ET-2 post-accelerating cavity

摘要

We report experiments evaluating the beam generation by the new 4-MV RLA injector and the subsequent beam transport and acceleration through the ET-2 post-accelerating cavity. Beams of 15 to 20 kA current were produced and successfully accelerated through the ET-2 gap. The produced beam has a Gaussian current density distribution and a radius of 5 mm. The beam profile and radius remain the same through acceleration, and the beam transport efficiency through the gap is 100%. Measurement results will be presented and compared with simulation.
