Beam Loss Monitors for the SwissFEL | |
|
||
| There are currently three types of monitors planned for tracking and minimizing beam losses at the SwissFEL. Fiber-based loss monitors will provide information on the longitudinal loss location, help reduce losses at undulators and measure losses due to insertion of wire scanners for transverse beam profile measurements. They shall be integrated to the Machine Protection System due to their fast response capabilities. The dose deposited over time at the undulators shall be measured with RadFETs and readout using the DOSFET L-02 reader. Characterization of all three types of loss monitors have been carried out at the SwissFEL Injector Test Facility. This contribution shall provide in-depth description of the monitors along with their complete readout chain and results from the characterization studies. | ||

| In the context of upcoming SwissFEL linear accelerator, we are working on a high-speed high-resolution instrument capable of delivering good sensitivity even in dark conditions. The camera selected is a PCO. Edge with SCMOS technology and an ultra-low noise sensor with 2560x2160 pixel resolution working at 100Hz. This allows for single bunch monitoring in SwissFEL, allowing eventually for on-the-fly inter-bunch image processing. The communication between the PCO. Edge camera and a last-generation Kintex7 FPGA has been demonstrated using a prototyping evaluation board and an 850-nm optical link connected to a 10Gbit SFP+ transceiver. Rudimentary packet processing has been implemented to confirm the satisfactory operation of the new link-layer protocol X-CameraLinkHS, specifically development for high-speed image transmission. We aim for online image processing and investigating the feasibility of achieving inter-bunch feedback (< 10 ms). | ||
