核技术所62室生产的9 MeV电子直线探伤加速器性能测试完成,满足了合同的要求,成为我室生产的第一台9 MeV探伤加速器。 将剂量率仪探头放在X射线中心轴线上距靶点2 m处,重复频率为240 Hz时,测得它的最大剂量率已达到3 000 rad/min。将剂量率仪探头放在X射线中心轴线上距靶1 m处, The completion of the 9 MeV electron linear inspection accelerator performance test conducted at Nuclear Technology Institute Room 62 met the contractual requirements and became the first 9 MeV testing accelerator to be manufactured in our facility. The dose rate probe was placed on the X-ray central axis at a distance of 2 m from the target at a repetition rate of 240 Hz and its maximum dose rate was found to have reached 3 000 rad / min. The dose rate probe on the X-ray center axis from the target at 1 m,
