“…In addition, the cleaning infrastructure should not interfere with other components of the optics compartment and should produce minimum contamination or damage. The front-end mirrors and the cleaning plasma are located in the tokamak vacuum chamber several tens of meters away from the power supply and the impedance-matching device, which are both installed in a radiation-safe environment [5,9].…”

“…In earlier experiments, feasibility of plasma cleaning was discussed for the Ultra-Wide Angle Visible Spectroscopy diagnostic system [2,17,18]. The electrical circuit of the plasma cleaning system was modeleld for the Visible Spectroscopy Reference System [5,19]. For the ETS system, parameters of critical components such as the notch filter element and the so-called 'pre-matching' vacuum L-C circuit were analytically considered for several operational frequencies [9], however were not yet studied experimentally.…”
