Some experiments on synchrotron radiation induced desorption at MAX

Andersson, Åke LU and Eriksson, Mikael LU (1995) In Vacuum 46(8-10). p.757-761
Abstract
At the synchrotron radiation facility MAX, the rest gas pressure in the storage rings is dominated by synchrotron radiation induced gas desorption. This desorption decreases with accumulated photon dose. The rate of decrease, or conditioning, is of greatest importance, since an acceptable machine performance, after opening the vacuum system, is highly dependent on the vacuum recovery. In MAX II the synchrotron radiation will hit specially designed absorbers. In order to finalize the design of these absorbers, a series of measurements were performed at the MAX I ring. Here we present the experimental results, which suggest that the area exposed to the emitted photoelectrons should be minimized, in order to obtain a higher rate of... (More)
