Abstract

A design of a simple ultrahigh vacuum apparatus with a facility for thermal desorption spectroscopy (TDS) is described. The most important technical details concerning the pumping system, working chamber and related electronics are presented. Few results of the testing of the TDS facility are shown, illustrating its most important performances. The temperature of the sample is increased linearly as: T (t) = T0 + βt, β being the heating rate whose values can be adjusted continuously from 2 Ks-1 to 90 Ks-1. T0 and T can be fixed within the interval 130-1500 K.
