| Abstract |
The LCLS2 is a CW superconducting LINAC driven X-ray free electron laser under construction at SLAC. The high beam rate of up to 1MHz, and ability to deliver electrons to multiple undulators and beam dumps, results in a beam diagnostics and control system that requires real time data processing in programmable logic. The SLAC Technical Innovation Directorate has developed a common hardware and firmware platform for beam instrumentation based on the ATCA crate format. The FPGAs are located on ATCA carrier cards, front ends and A-D / D-A are on AMC cards that are connected to the carriers by high speed serial JESD links. External communication is through the ATCA backplane, with interlocks and low frequency components on the ATCA RTM. This platform is used for a variety of high speed diagnostics including stripline and cavity BPMs.
