Development of ultra-fast diamond-sensor based systems for advanced accelerator diagnostics

The Advanced Accelerator Diagnostics collabora-tion has been developing diamond-sensor based high bandwidth position-sensitive diagnostics for applica-tion at next generation XFELs and other accelerator facilities. A pass-through diagnostic with 50 MHz rate capability has demonstrated pulse-by-pulse position sensitivity of 1% of delivered beam width. Progress has been made in upgrading this diagnostic approach to multi-GHz operation, involving an integrated detec-tion system design making use of a compact signal path and proximate high-bandwidth readout ASIC. Preliminary results are presented on the performance of both the signal path and ASIC. Possible additional applications, including precision event timing and plasma ignition diagnosis, are introduced.
