论文摘要
具有高加速度梯度的脉冲SRF Linac经历了由Lorentz力引起的频率转移（LFD）。具有共振控制算法的压电执行器可以将空腔频率保持在标称级别，从而降低RF功率。这项研究使用带有压电执行器的双杠杆调谐器进行补偿，并使用另一个压电执行器来模拟Lorentz力脉冲的效果。双杠杆调谐器通过增加腔 - 调节器系统的刚度，从而降低LFD的影响来具有优势。测试是在室温下进行的，并穿着1.3 GHz 9细胞腔。
Pulsed SRF linacs with high accelerating gradients experience large frequency shifts caused by Lorentz force detuning (LFD). A piezoelectric actuator with a resonance control algorithm can maintain the cavity frequency at the nominal level, thus reducing the RF power. This study uses a double lever tuner with a piezoelectric actuator for compensation and another piezoelectric actuator to simulate the effects of the Lorentz force pulse. A double lever tuner has an advantage by increasing the stiffness of the cavity-tuner system, thus reducing the impact of LFD. The tests are conducted at room temperature and with a dressed 1.3 GHz 9-cell cavity.
