为了开展加速器小型化技术研究, 进行了C波段2 MeV驻波加速器研制工作。目前, 该加速器研制取得了显著进展, 完成了全密封加速管的焊接, 建立了加速器热测实验平台。在重复频率50 Hz情况下, 进行了初步热测出束实验, 利用电离室剂量仪测试了加速器靶前1 m处的X射线剂量率, 并利用钢吸收法测试了电子束的能量。初步实验结果表明：电子束能量约2.5 MeV, 剂量率超过330 mGy/(min·m)。

A C-band 2 MeV standing wave accelerator is under development for engineering research on accelerator miniatu-rization. At present, significant progress has been achieved. The accelerating tube has been fully sealed, and the hot test platform for the accelerator has been built. At the repetition rate of 50 Hz, preliminary power test has been performed. It used the ionization chamber dose monitor to test the dose rate of X-rays at 1 m before the target, and the steel absorption method to test the energy of the electron beam. The preliminary test results show that, the beam energy is about 2.5 MeV, and the dose rate can be over 330 mGy/(min·m).
