Development of a monoenergetic ultraslow antiproton beam source for high-precision investigation

Abstract

The ASACUSA collaboration developed an ultraslow antiproton beam source, monoenergetic ultraslow antiproton source for high-precision investigation (MUSASHI), consisting of an electromagnetic trap with a liquid He free superconducting solenoid and a low energy antiproton beam transport line. The MUSASHI was capable of trapping and cooling more than $1\ifmmode\times\else\texttimes\fi{}{10}^{7}$ antiprotons and extracting them as an ultraslow antiproton beam with energy of 150--250 eV.
