Abstract

A capacitive diaphragm gauge (CDG) has been modified to measure the amount of accumulated in-vessel dust in tokamaks. In order to pin point the mass load on the CDG, aluminum dish is used. Calibrations show that the CDG has a measurement range from 2.2 g to 6.7 g with a minimum detection mass of 30 mg. Long term stability of measured signal is obtained at least more than 12 h operation with the atmospheric pressure and under vacuum. The CDG will be installed in KSTAR (Korea Superconducting Tokamak Advanced Research) device in 2012 campaign to measure the amount of in-vessel dusts.
