David, George | Temperature Cycle |
04:40
Target density is hovering between 2.0e-8 and 2.3e-8, sometimes dipping below 2.0e-8
We will conduct a temperature walkthrough while there is no beam,
04:40: setpoint 125K
04:46 setpoint 95K
04:56 setpoint 108K
04:59 setpoint 110K
05:00 setpoint 112K (here improved from 110K)
05:03 setpoint 114K
05:08 setpoint 113K
05:11
113K seems good, fluctuating between 2.3e-8 and 3.1e-8
will leave temperature here |

David, George | Ion Source Update |
02:25
Zoran was unable to ignite the ion source.
He has given some parameters to the control room so they can wiggle stuff around and try and ignite it.
He also said it may at some point ignite itself.
In worse case scenario, the person who usually manages the ion source will come in from 7am-8am, read Zoran's notes and try and get it working again.
Also target density seems a little worse but still hanging above 2e-8 to 2e-4 |

David, George | Beam Intensity Drop |
00:38
Intensity in the ring dropped by 2 orders of magnitude to 5e5 on injection
Lost rutherford rate (as seen in last e-log post)
All pressures seem fine
00:48
Called main control room, said they will take a look
00:59
Servo motor control restarted and homed
01:11
Ion source is confirmed to be off
Zoran will try and fix it, should take 1hr or so and not guaranteed to work.

David, George | Current status |
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)

PM, LV | target temperature walkthrough |
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
