| 摘 要： | 理论分析了兰州重离子加速器腔体的低电平稳定系统中各传输通道对腔体的长期稳定度的影响，根据现有低电平稳定系统的实际情况，提出了用附加测试电缆来补偿反馈电缆漂移的方法。测试了环境温度的变化对电缆在实施补偿前后的相位与损耗的影响，测试结果表明：采用电缆补偿后的长期相位稳定度可以降低到原来的1/50，长期幅度漂移可以最少降低到原来的1/10。

| Abstract: | A compensating method for the coaxial line drift due to the temperature change using an additional measuring coaxial line is proposed for the low-level radio frequency(RF) control system of Heavy Ion Research Facility in Lanzhou (HIRFL). We measured the temperature effects on the RF phase and RF loss at the SYV50-2-41 cable with and without using the additional measuring coaxial line, respectively. The measured results show that, the long-term phase instability with compensation can be reduced to 1/50 of the one without compensation; the long-term amplitude drift can be reduced to 1/10 at least. |
