Problems still to be addressed

This document outlines the key problems that still need to be resolved for optimal operation of the LPRF system. Important specifications include maintaining full voltage, bias control, amplitude control, and the generation of clean RF waveforms, all managed through ISIS LPRF. Additionally, the system must demonstrate reliable operation over a week, alongside automatic cavity tuning based on various voltage phases. Reliability issues with cavity cooling pipework need urgent attention. It is estimated that two weeks of experimental work and a week of soak testing is required to support advancements for the ISIS synchrotron SP6.

  1. Problems still to be addressed  Meet full specification on all parameters e.g. - full voltages - bias on tune throughout - amplitude control - clean RF waveforms - control through ISIS LPRF  Demonstrate reliable running for about 1 week  Automatic cavity tuning via - phase of input/output voltages - or phase of output grid/gap voltages - or phase of output RF current/gap volts

  2.  Gap volts and output RF current are available on the mezzanine in R5.4, but neet to be available in the Diagnostics Room at System 6 2RF LPRF  Pipework for cavity cooling is unreliable and should be replaced with something better Derek estimates about 2 weeks’ experimental time plus at least a week’s soak testing before we could make a convincing case to run into ISIS synchrotron SP6
