Description
The wall surface carbonization experiment was carried out in the HL-1 tokamak with AC discharge (50 Hx, 2 kw) in a gas mixture (CH4:H2 = 1:4, 5 x 10-3Pa). The samples exposed to carbonization have been analysed by AES and SIMS. No limiter material Mo deposition was found. Molybdenum contraction in the HL-1 plasma is reduced to 20% of that before carbonization. Particle confinement time τp and hydrogen recycling coefficient R increase by about 20%
