Аннотация

The validation of spectroscopic method for localization of the water plume around a coolant leak in ITER plasma chamber based on the excitation of coolant particles in plasma near wall is presented. The sensitivity of OH hydroxyl and Xe as minor admixtures to cooling water detection in different types of plasma discharges relevant to ITER tested in stellarator L-2M and hollow cathode glow discharge. The limit of sensitivity of water detection in hot plasma using OH* hydroxyl band is estimated as 3 × 10-5 Pa m 3 s-1and ∼1 × 10-6 Pa m3 s-1 for Xe. For glow discharge conditions measured sensitivity of OH* detection is equal to 3 × 10-5 Pa m3 s-1. © 2013 Elsevier B.V. All rights reserved.
