Abstract:

A slow positron beamline has been developed using a 30-MeV L-band electron linear accelerator at Kyoto University. Based on particle-transport simulations to evaluate positron generation, the optimum thickness of the tungsten converter was determined. Through positron trajectory simulations in a Penning trap (linear storage section), the electrode types were compared to realize the best storage performance; the importance of the uniformity and precision of magnetic fields using supplementary coils was highlighted. During the commissioning experiments, positron transport to the beamline end was confirmed, along with the operation of the linear storage section.
