00:30
Pressure in S1 slightly decreased from before but still high enough to measure data.
One new count at 20MeV
Target density at S1: 2e-8 - 2.7e-8
Pressures OK (one small spike just before 00:00 in YR08)
System Checks OK
White rabbit fail diff: 49
Data write speed: ~1.4Mb/s
Beam intensity at injection: ~7.7e7
Cryo Temp Setpoint: 110K
(Beam intensity in ring dropped as I was writing which is why there is no rutherford peak on exRate image)

A target temperature walkthrough has been initiated at 20:41 since the target density at S1 had slightly decreased (with ~0.1-0.2)
Current temprature 116K
set to 126K at 20:41
set to 95K at 20:47:30
set to 108.5K at 21:01:30, at this temperature was a sweetspot observerd for target density.
set to 109.7 at 21:08:30
set to 110K at 21:13:30 - we keep at this value for a while. the values at S1 are changing between 2.2-2.9e-8 |

CB, MS, SS, ML | Synced pneumatic motion |
New run R84
Attempting to sync pneumatic movement with ring. Still see something on t out -> p out
Command to move out was being given relative to the wrong time.
Fixed it. Still see one-two events every time we move out around 4-6 MeV. Attempted to greatly increase time before next injection - no difference. Microphonics from moving the detectors? It's just one-two counts on entire detector, acceptable.
New run R85
Now moving in/out

Rutherford rate is reduced from previous entries. Avergae peak height appears to be ~50 counts. Fluctuations in peak height and E4 pressure are quite high. Temperature has been cycled, nozzle position has been optimised and different temperatures have been trialled however density cannot be maintained at a decent level.
