Description
The first MTCA.4 based laser synchronization system is presented. We use a standard MTCA.4 crate where a high frequency RF front-end detector feeds a fast digitizer AMC board. The processing is carried out in the FPGA located on the digitizer which transmits the control output over a serial link routed on the standard AMC backplane to a receiver FPGA located on a neighboring AMC board. The hosting FPGA on this board transmits the control signal to the DACs on the RTM side which is composed of high voltage piezo pre-amplifiers and high-voltage piezo drivers. The piezo driver acts on the piezo stretcher of the Er-fibre laser which controls the frequency of the laser resonator. Such solution opens many possibilities for processing algorithms and connectivity with other system. Some of the main limitations and their mitigations are presented.
