*Ultra-Slow antiproton beam transport line [#aec76f79]
After the cooling, antiprotons were extracted from the trap and transported to experimental chambers via this transport beam line.
** differential pumping system [#d2e7b5fb]
To maintain the pressure difference between the Antiproton trap and experimental chambers with gas targets, this beam line was designed to work a differential pumping system.
** elctrostatic lens [#v7bc7236]
Three electrostatic lens systems were installed to focus ultra-slow antiproton beams.
