本工作主要是对一台高压倍加器的辐射场进行了测量。结果表明,目前该高压倍加器的运行是安全的。实验厅内中子剂量主要来自电缆沟和迷宫的散射。在中子产额为2×10~9中子/秒条件下运行30分钟,距靶20厘米处由于中子活化引起的γ辐照率约20微伦/秒。机械泵油中氚的浓度为3×10~(-5)居里/升,机械泵排出口氚的浓度在(4×10~(-8)～3×10~(-6))范围内。
This work is mainly on a high voltage doubler radiation field was measured. The results show that the current high pressure doubler operation is safe. The neutron dose in the laboratory mainly comes from the scattering of cable ditch and maze. Operating at a neutron yield of 2x10-9 neutrons per second for 30 minutes, the gamma irradiation at 20 cm from the target due to neutron activation is about 20 micro-lux per second. The concentration of tritium in the mechanical pump oil is 3 × 10 -5 (Curie / liter) and the concentration of tritium in the mechanical pump outlet is in the range of (4 × 10 -8 to 3 × 10 -6) .
