摘要: 中国锦屏地下实验室（CJPL）坐落于四川省锦屏山中，利用水电站修建的隧道建成。由于其本底环境极低，非常适合开展低本底实验测量。一台基于ECR源的400 kV强流加速器将安装在CJPL中，其可以为核天体物理实验提供流强为12 emA的质子束流，6 emA的He⁺束流和2.5 emA的He²⁺束流。拟通过非共振反应¹²C（p，γ）¹³N以及一系列的共振反应²⁷Al（p，γ）²⁸Si等，对加速器的束流能量进行精确刻度，对束流的能量展宽以及长期稳定性进行测量。由于该加速器正在中国原子能科学研究院进行地面调试，我们利用中国科学院近代物理研究所的320 kV研究平台，进行了¹²C（p，γ）¹³N和²⁷Al（p，γ）²⁸Si反应的测试实验。测量结果表明，在质子束流能量为224 keV时，束流的能量展宽约为1.0 keV，束流能量在连续4小时的测量期间，其晃动幅度远小于±200 eV。

China JinPing underground Laboratory (CJPL) was established inside the tunnels piercing Jinping Mountain in Sichuan Province, China, which can provide an ideal environment for low background experiment. A new 400 kV accelerator, with high current based on an ECR source, will be placed at this underground laboratory for nuclear astrophysics experiment. The beam characteristics of this accelerator, like absolute energy, energy spread, and long-term energy stability, will be determined by several wellknown resonance and non-resonance reactions. Due to the new accelerator still being under construction, the resonance reaction of ²⁷Al(p, γ)²⁸Si and non-resonance ¹²C(p, γ)¹³N were studied at the 320 kV highvoltage platform in Institute Modern Physics of CAS in Lanzhou. The energy spread of proton beam is about 1.0 keV at proton energy E_p=224 keV and the long-term energy stability of proton beam is much better than 200 eV during 4 hours measurement.
