l/s Ion Pump
/ 87-900-091-01
During installation, keep the pump and system clean. Avoid
touching surfaces which will ultimately be under vacuum. When
the VacIon pump is open to the atmosphere, take care to avoid
introducing foreign particles, oil, solder flux, or any volatile
substances. Before attaching the pump, clean the system
thoroughly. Chemical cleaning is the most complete cleaning
method for the vacuum system; however, do not attempt it when
pockets and crevices exist that will prevent thorough rinsing.
Degreasing with an acetone or methanol followed by water-
rinsing is usually sufficient.
To achieve maximum pumping speed, connect the pump to the
system with a tube that has the shortest length and the largest
diameter possible.
For ultrahigh vacuum work, joints should be tungsten inert gas
welded, hydrogen brazed, or vacuum brazed. Do not use flux in
making joints for ultrahigh vacuum.
Gaskets in the system should be of soft metal such as annealed
copper, aluminum, or gold.
After the pump is sealed in place, leak-check the entire system.
Assemble the magnet to the pump.
