Abstract

¹³CH₄ was injected through an aperture in a roof-like test limiter covered by a graphite, tungsten or molybdenum plate during Ohmic discharges. The evolution of the deposition pattern was studied by in situ reflectometry during each plasma pulse. Amounts of locally deposited ¹³C and co-deposited background ¹²C in each shot were determined post-mortem. The ¹³C deposition efficiency is in a range of 0.05-0.2% and grows with the increasing amount of ¹²C. For the same ¹²C content the efficiency is of 0.11% for tungsten, 0.14% for molybdenum and 0.17% for graphite.
