Piezoelectric pulse leak valve in the tokamak TM-1-MH device
Abstract
The principle and function of a pulse leak valve, working on the basis of the piezoelectric effect, is described. By the control of the voltage causing the piezoelectric effect it is possible to change the gas flux in the range of more than five orders of magnitude. This leak valve is operating in the tokamak TM-1-MH device, which is designed for the study of the supplementary high temperature plasma heating for thermonuclear research purposes. The compensation of the metal wall ion pumping during the plasma discharge was achieved, and the regime with the constant electron density was produced.
