David, Pierre-Michell | Current status | We have recovered the beam at 01:49, after such a long time we had no target so we increased from 80K to 120K at 01:52. 02:01 update 120K-->95K as we have observed around that temperature always fluctuations and is safer.

David, Pierre-Michell | Current status | So far looks like with a temperature of 95K the target is maintained with a reasonable density throughout long periods of time.

David, Pierre-Michell | Current status | We have decreased the temperatur> 95K --> 90K. At 95K the target was stable, but let's try to increase the density a bit.

Temperature setpoint 115 K
Rutherford rate appears fairly stable. Fluctuations from a max peak of 10^2 to a minimum of ~40 peak hieght. Fluctuates remain lower than at 95 K.
Temperatures OK
System checks OK - white rabbit attached.
Leakage current ~ 3.236 uA
Data rate ~1177 kb/sec
Merger OK
Ring vacuum levels appear to have stablised from previous large fluctuations. Avg ring pressure decreased to 3.8E-10 mbar from 7.5E-10 mbar at start of the shift. (attachment 9)
00:51
Rutherford rate still stable. Fluctuations have reduced slightly. Min peak height now ~60 counts, max peak ~10^2 counts. (attachment 10)
Ring vacuum avg = 3.2 E-10 mbar.
E1 pump current ~ 2.4 A |
