A Method for Avoiding Following Ion Leakage from a Penning Trap

Abstract

Ion leakages from a Penning trap are studied in the BX-U linear trap [K. Akaike and H. Himura, Phys. Plasmas 25, 122108 (2018).]. The following leakage stops as the rise time of the upstream potential barrier sets to be longer. In the case, the number of trapped ions increases with the ion plasma still oscillating in the potential well of the Penning trap.
