Cryopump tools are very important in keeping the
equipment performing properly. Cryopumps are a workhorse and hydrocarbon free but
do require maintenance and proper handling.

Decontamination Manifold
The decontamination manifold is
used for decontaminating the system of gaseous contamination. A contaminated
helium circuit will cause the Cryopump to operate in a noisy manner, typically
referred to as ratcheting, which degrades Cryopump performance.

15K Charcoal array kit
Gases pumped by a cryopump are captured within the pump. Poor cryopump
performance may be due to saturation of the 15K cryo-adsorbing charcoal array.
Occasionally the pumping surfaces will fill to capacity and require
regeneration. Over time, the charcoal array will become contaminated and need to
be replaced.
