Description
The k=192 synchrocyclotron is pumped by 2 large diffusion pumps with cryo baffles and
has internal Meissner cryo traps. The CELSIUS storage ring is pumped by a combination of
ion pumps and sublimation pumps. Large H2 and D2 gas loads from the pellet target of
the CELSIUS-WASA experiment are pumped by cryo pumps and NEG pumps to give a low
enough pressure in the electron cooler. Similarly, cryo pumps are used to prevent heavy
noble gases (Ar, Kr and Xe) from the cluster jet target to limit the beam lifetime.
