论文摘要
对于任何新的加速器，LLRF和RF系统开发过程中都有许多阶段，可以利用高功率RF系统和RF腔的硬件仿真。 LLRF开发，台式测试，控制系统的开发和安装系统的测试必须在SRF腔进行测试之前进行。 PIP-II LINAC具有三个SRF腔的频率：162.5 MHz，325 MHz和650 MHz，并且选择了一个简单的模拟模拟器设计，可以满足所有空腔类型的lorentz Force nounaning和Microphonics的调谐误差。该仿真器设计利用一个石英晶体为65Hz的带宽为〜4 MHz，在650MHz时提供了〜1.3 x 10^7的Q。本文将讨论该模拟器的设计和测试结果。
There are many stages in the LLRF and RF system development process for any new accelerator that can take advantage of hardware emulation of the high-power RF system and RF cavities. LLRF development, bench testing, control system development and testing of installed systems must happen well before SRF cavities are available for test. The PIP-II Linac has three frequencies of SRF cavities, 162.5 MHz, 325 MHz and 650 MHz and a simple analog emulator design has been chosen that can meet the cavity bandwidth requirements, provide tuning errors to emulate Lorentz force detuning and microphonics for all cavity types. This emulator design utilizes a quartz crystal with a bandwidth of 65Hz at an IF of ~ 4 MHz, providing a Q of ~ 1.3 x 10^7 at 650MHz. This paper will discuss the design and test results of this emulator.
