Anti-Particle Accumulation for Low Energy Exotic Beams | |
|
||
| On behalf of ASACUSA-MUSASHI collaboration, the recent result for the production of low energy antihydrogen beams is presented. In Antiproton Decelerator (AD) at CERN, low energy antiproton beams of 5.6 MeV have been delivered for physics experiments since 1999. With the help of RF group at CERN, Atomic Spectroscopy And Collisions Using Slow Antiprotons (ASACUSA) collaboration installed the unique RFQ decelerator (RFQD), which can provide ~100 keV pulsed antiproton beams for its various experimental programs. Furthermore, the Mono-energetic Ultra Slow Antiproton Source for High-precision Investigations (MUSASHI) used a Penning-Malmberg trap to produce antiproton beams with the energy of 100 to 1000 eV. In 2010, the synthesis of low energy anti-hydrogen atoms in the Cusp trap with the use of 150eV antiproton beams from MUSASHI trap was reported. The purpose of producing low energy anti-hydrogen atoms in a cusped magnetic field is to extract a polarized anti-hydrogen beam to a field free region, so that the hyperfine structure of anti-hydrogen atoms can be measured with a necessary precision. | ||
