在深圳超导软X射线自由电子激光装置(S3FEL)中,连续波(CW)低电平射频(LLRF)系统执行关键功能,包括调节加速腔的功率耦合、调控射频场的幅度和相位,以及维持腔体的谐振频率和相位。这些功能对于确保电子束在加速相位下运行至关重要。在S3FEL中,每个超导腔由一台固态放大器(SSA)驱动,每台SSA配备一套专用的LLRF系统。根据所采用的不同加速腔类型,S3FEL的CW LLRF系统分为四类:1. 主加速器LLRF系统(超导,1.3 GHz;数量:168套),2. 谐波腔LLRF系统(超导,3.9 GHz;数量:16套),3. VHF电子枪LLRF系统(常温,216 MHz;数量:4套),4. 聚束器LLRF系统(常温,1.3 GHz;数量:2套)。这四类LLRF系统在射频场和加速腔控制方面具有不同的要求。本报告介绍了这四种CW LLRF系统的初步设计方案。

英文摘要

In the Shenzhen Superconducting Soft X-ray Free Electron Laser (S3FEL), Continuous Wave (CW) Low-Level Radio Frequency (LLRF) systems perform critical functions including adjusting the power coupling of accelerator cavities, regulating the amplitude and phase of the RF field, and maintaining the resonance frequency and phase of the cavities. These functions are essential to ensure the electron beam operates at the accelerating phase. Within S3FEL, each superconducting cavity is driven by a solid-state amplifier (SSA), with each SSA paired with a dedicated LLRF system. Based on the distinct acceleration cavities employed, the CW LLRF systems for S3FEL are categorized into four types: 1. Primary accelerator LLRF systems (superconducting, 1.3 GHz; quantity: 168), 2. Harmonic cavity LLRF systems (superconducting, 3.9 GHz; quantity: 16), 3. VHF electron gun LLRF systems (room temperature, 216 MHz; quantity: 4), 4. Buncher LLRF systems (room temperature, 1.3 GHz; quantity: 2). These four LLRF system categories exhibit differing requirements for RF field and acceleration cavity control. This report presents the preliminary design schemes for these four types of CW LLRF systems.
