FLASH/TTF装置空腔梯度和输入RF稳定性的最新结果
Latest Results on Cavity Gradient and Input RF Stability at FLASH/TTF Facility
摘要：
DESY的FLASH L波段（1.3 GHz）超导加速器设施有一个低电平RF（LLRF）系统，类似于ILC的设想。该系统具有广泛的监测能力，用于收集与ILC有关的性能数据。最近，记录了三个8腔低温模块在射束开启和关闭时的波形数据，以评估输入RF和腔梯度稳定性，并研究在800μ \s脉冲期间实现恒定梯度所需的RF开销。在本文中，我们提出了最近的实验结果，并讨论了脉冲到脉冲的输入射频和腔梯度的稳定性的光束开和关的情况下。此外，将描述在射束关闭情况下观察到的梯度变化的模型。
英文摘要：
The FLASH L-band (1.3 GHz) superconducting accelerator facility at DESY has a Low Level RF (LLRF) system that is similar to that envisioned for ILC. This system has extensive monitoring capability and was used to gather performance data relevant to ILC. Recently, waveform data were recorded with both beam on and off for three, 8-cavity cryomodules to evaluate the input RF and cavity gradient stability and study the rf overhead required to achieve constant gradient during the 800μ\s pulses. In this paper, we present the recent experimental results and discuss the pulse-to-pulse input rf and cavity gradient stability for both the beam on and off cases. In addition, a model of the gradient variation observed in the beam off case will be described.
