ION BOMBARDMENT INDUCED RE-EMISSION STUDIES OF ARGON IN AN IONIZATION PUMP
Journal Article

· Brit. J. Appl. Phys.
The re-emission of ionically pumped argon in a glass diode ion pump, when bombarded with the other inert gases He, Ne, Kr, and Xe, was studied. It was found that the removal efficiency increases to an apparent saturation with increasing bombarding ion energy, but even at the highest bombarding energy used (1 kev) it was never possible to recover completely all sorbed primary gas. This and other evidence leads to the conclusion that argon is released from the glass by transfer of sufficient energy by a bombarding ion, via the glass atoms, to the sorbed argon: sputtering of the glass with simultaneous argon release appears to be unimportant. The effective gas sputtering coefficients for argon releasing argon and the maximum possible surface coverage are deduced. (auth)
