  1. System I Update Nick Shipman 02.04.2013

  2. Overview • No new data, (almost) no new analysis, but productive week (really!) • Together with Anders Korsback measured the size of the current charging pulse in every situation imaginable! • Found and fixed the issue which had been causing all the gap measurement problems. (A ball bearing had fallen out) • Ordered almost all the parts necessary for a coax-switch box. (Accept stepper motor for which I am awaiting a quote). • Helped Will Vollenbergto remove the old pumping group and gauges from system 1 and replaced with a newer one. • Over the weekend I started a bakeout. • The power tripped and the system vented with the bakeout still running (the main valve does not close automatically at the moment). I restarted this morning and the pressure is currently 5.6E-7 mbar and the temperature is 105 deg C.

  3. BDR vs. E

  4. Outlook • Restart gap dependence measurements, hopefully the results will now make more sense. • Fix small problem with controlling the main valve on the system. • Continue analysis, especially interested in time dependence.
