Description

The one-channel two-frequency monitor intended for measuring the plasma density in tokamak devices is described. The monitor operation principle is based on measuring the phase shift between two near frequency microwave signals passed through the plasma along one and same chord. The principle scheme of the monitor and its main characteristics are presented. The monitor allows to measure the plasma density in the range of 0.7x1012 - 0.7x1014 cm-3 with the accuracy not worse 1% and the time resolution up to 30 ns

Abstract (Russian)

Описан одноканальный двухчастотный монитор, предназначенный для измерения плотности плазмы в токамаках. Принцип действия монитора основан на измерении сдвига фаз между двумя близкими по частоте микроволновыми сигналами, прошедшими через плазму по одной и той же хорде. Приведены принципиальная схема монитора и его основные характеристики. Прибор позволяет осуществлять измерения плотности плазмы в диапазоне 0.7х1012 - 0.7x1014 см-3 c точностью не хуже 1% и временным разрешением - вплоть до 30 нс
