Design of an Ultra-Compact Stripline BPM Receiver using MicroTCA for LCLS-II at SLAC
Xu, Chengcheng.
The Linac Coherent Light Source II (LCLS II) is a free electron laser (FEL) light source. LCLS II will produce 0.5 to 77 Angstroms soft and hard x-rays. In order to achieve this high level of performance, the beam position measurement system needs to be accurate so the electron beam can be stable. The LCLS-II stripline Beam Position Monitor (BPM) system has a dynamic range of 10pC to 1nC bunch charge. The system has a resolution requirement of 5m. The BPM system uses the MicroTCA (Micro Tel...

The Linac Coherent Light Source II (LCLS II) is a free electron laser (FEL) light source. LCLS II will produce 0.5 to 77 Angstroms soft and hard x-rays. In order to achieve this high level of performance, the beam position measurement system needs to be accurate so the electron beam can be stable. The LCLS-II stripline Beam Position Monitor (BPM) system has a dynamic range of 10pC to 1nC bunch charge. The system has a resolution requirement of 5m. The BPM system uses the MicroTCA (Micro Telecommunication Computing Architecture) physics platform that consists of an analog front-end (AFE) and a 16-bit analog to digital converter (ADC) module. This paper will discuss the hardware design, architecture, and performance measurements of this system using the SLAC LINAC. The hardware architecture includes bandpass filter at 300MHz with 15 MHz band-width, and an automated BPM calibration process. Show Partial Abstract
