Most of the CARME is covered by the baking tent. The tent needs to be closed and a bit covered from the front
(upstream), end (downstream), and bottom side. TCs are labeled with a marker in the sequence 1-1 to 2-8.
1-1 Internal TC 1
1-2 Internal TC 2
1-3 Internal TC 3
1-4 CARME front top
1-5 CARME front bottom
1-6 Top hanging middle

|
NEG pump electrical connections tested - all connections sound.
Detector carriers have been redrilled and are currently being cleaned. Carriers were checked within the chamber, mounting much easier with new
hole. Distances to NEG feedthroughs and thermocouple feedthrough from the carrier also checked. NEG feedthroughs have sufficient separation now moved, |

Thu Nov 18 13:50:51 2021, CB RSS, Thermocamera images 14x
|
Used thermocamera provided by GSI beam diagnostic division to take some pictures of YR09. See attached.
Due to aluminium outer wrapping some reflections are inevitable, but tried to only take pictures of heat spots that did not disapper from different
angles. |

Thu Jan 4 13:15:10 2024, CB, JM, Tent removed - bias test
|
Removed tent, octagon, Neg cables.
Disconnected and removed Baking Pi, TC08, thermocouples.
Tested new rails, plates, fees - it fits. Need to check on the flange next. |

Mon Feb 28 01:16:02 2022, JM, OF, Temperature decrease 115K to 110K
|
02:15
Density remains stable at 155 K
Temperature setpoint decreased by 1K. Aim to get to 110 K to see if higher stable density can be achieved. |
|
Mon Feb 28 05:04:47 2022, JM, OF, Temperature cycle to 125K
|
06:01
Rutherford rate was decreased compared to previous values. Max rate ~ 50 counts for the peak, average ~20 counts.
Temperature increased to 125 K |
|
Mon Feb 28 13:56:02 2022, JG, CB, Temperature cycle to 125K
|
14:45
Rutherford rate was decreased significantly for longer period.
Temperature increased to 125 K |
|
Tue Mar 1 04:07:31 2022, JM, EM, Temperature cycle
|
Have been unable to achieve decent target density with temperature cycling so far. Will attempt to go up to 300 k and back down to around 115 k which
proved successful in previous shifts. |
|
Tue Mar 1 03:19:50 2022, JM, EM, Temperature Cycle
|
04:20
Did another temperature cycle (118 K -> 125 K -> 95 K -> 116 K) trying to improve the pressures at the target and the detector count
rate. |

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, |

Sun Jun 16 22:40:11 2024, JM, Target overlap test - R81
|
23:10
Beam set to bunched mode to observe beam lifetime.
Electron cooler voltage setpoint kept at 246.8 V. Note this is 0.5 V lower than the previous test where the setpoint was 247.3 V |

Tue Jun 11 19:44:48 2024, OF, SS, Target out and at He
|
Target has been moved out and H2 switched off. Changed to He.
Nikos will repair nozzle tomorrow morning. Remote checks until then. |
|
Wed Jun 5 08:34:04 2024, JM. DB, PC, Target nozzle change
|
09:30
Target density has not improved despite efforts last night. Mid 10 - low 11 density range. We will try to change the nozzle.
Target nozzle moved to the out position. |

Fri Feb 2 09:58:58 2024, TD, TapeServer not writng data to disk - plus fix 7x
|
DAQ and NewMerger appear to be cofigured correctly.
Can allocate device, create volume and open file with TapeServer but cannot write data.
