Temperature controlled outgassing of graphite samples for thermodesorption spectroscopy investigations

摘要

In this paper, we describe a temperature controlled outgassing measurement in the case of electron-beam heating of graphite samples used in divertors of Tokamak-type installations. On the basis of a discrete-time process model in the state space, we developed finite-time settling control of the sample's temperature. We further present the response of closed-loop systems to a unit-step load disturbance and a unit-step reference input.
