ITF Recovery - Afternoon Shift 21/01

Yesterday's afternoon was devoted to the recovery of the ITF:

  • after a couple of tweaks, both the DIFFp and the PR loop could be engaged automatically during lock acquisition with the usual parameters (gains, setpoints);
  • the COMMp loop could be engaged without issues once the other two were closed;
  • however this was not possible for the BS loop, I am not sure if this is related just to the working point or there was something different with the signal, to be checked; changing the gains had the only effect to delay or hasten the loss of the control;
  • the phases of the RFC and B2 PDs were adjusted.
