    • Install SSH Enable/Disable mimic : Pierrick : Stands
  • Magnet and channel commissioning
  • can reproduce quench protect trip operation with only one power supply on ECE
  • can reach final desired current and sit there for about an hour. Can see noise growing on trace for
  • combined voltage taps. Looks like a set of spikes with ringing over a period of 10s with spikes growning
  • in amplitude with time until the trip level is reached. Maybe coming from PS and its controller but don't
  • know yet. Could be many things.
  • PRY/Magnets are also moving by up to 4 mm and Josef wants to stop this. Josef wants to put spacers between
  • the SSs and the PRY. Jason is looking at this and has a design
  • but it won't be ready for this run. Crap - what do I do with shifters. Possibly could get this done for the end of
  • the next shutdown. **
  • Whats the plan? We run the ECE with a single PS tomorrow and look at ringing behaviour. Whilst ringing adjust
  • PS behaviour to see what effect this has.
  • Victoria : is there any historical data from when SSU/D were powered together as there was less movement then?
  • Mike : noone's looked.
  • JC : can see a 0.1 Hz signal on FC all the time from somewhere. When we see a spike on SSU we also see a spike on the
  • FC.
  • Trips are close together - growth of spikes. Time will be needed.
  • Plots look OK
  • JC : can the tracker see if the SSs have shifted.
  • MU : Paul was going to look at it in simulation.
  • Paul : haven't got too far. Compare tracker distributions before and after powering and see if there is any difference.
  • JC wrote a document about running the FC and has a document for shifters.
