Description

Low-Level RF and timing systems are of primary importance to operate laser-driven RF-Gun. The laser oscillator piezo feedback synchronizes the phase between laser pulse and accelerating field. The laser pulse picking is conducted by the acousto-optic modulator in order to generate from single shot to tens pulses per facility machine cycle. The acousto-optic modulator operation is synchronized by the trigger pulses arrival time. The trigger pulses generation and delay are controlled by the digital time delay modules, which are locked to the accelerating field clock signal. Both systems are being commissioned at the laser-driven RF-Gun test-bench at the Laboratory of Nuclear Problems, Joint Institute for Nuclear Research. The test-bench Low-Level RF and timing systems current status is presented in this report. Moreover, the laser oscillator piezo feedback analogue and digital signal processing chains, including algorithms, are demonstrated in details.
