Attachments 1-3 fasteners, fittings found amongst earlier shipments. I assume that the STFC DL cleaned items are for the internal detector mount assembly.

Wed Aug 10 10:33:03 2022, TD, ML, JM, NP, Meeting at YR09 to discuss options for CARME operations to February 2022

Initial discussions of proposals to provide open CARME chamber and provide access to near and far detector chambers

Wed May 24 09:54:56 2023, JM, CB, Maximum detector positions 9x
|
The detectors were moved into the beam axis using the motors to check the maximum distance they can be moved in without collision with one another.
Movement of both pneumatic motors results in a separation of ~ 4 cm between the detectors.
The servo motors for left and right were each moved in by 1 cm -> results in separation of 2 cm between the detectors |

Sun Jan 7 15:38:57 2024, CB, JM, Manifolds mostly assembled + bias overnight check
|
Assembled most of the connectors on the new (green) manifolds. Two blanking pulgs stuck when mounting - cannot remove them or tighten them. Swarf? Will
ask Davide's help tomorrow. Cannot use the manifold until this is fixed.
Checked FEE assembly in cassette. Need to shorten black Delrin supports by ~6 mm. Holes should end up in the correct position thanks to rails |
|
Mon Jan 8 19:29:57 2024, CB, JM, Manifold repaired + fee assembly in bench
|
Davide extracted the stuck blind plugs and re-threaded all missing ports. Completed manifold assembly, except for main inlet/outlet - left for plumber.
Cut 8x2 2m hoses and assembled with Swagelok quikfit and teflon ferrules.
We're missing back ferrules in brass for the repaired fees. It should be possible to buy them from GSI. |

Wed Jan 10 19:27:08 2024, CB, JM, Manifold and more bias tests
|
Mounted water manifold on CARME with help from GSI plumber. Connected all the hoses with Swagelok self-locking connectors. Tested for water leaks - it
leaks from nearly every port. The issue appear to be the connections between the manifold and the plugs, as opposed to the plugs and the hoses which do
not leak. |

Thu Feb 24 04:17:35 2022, CB, TD (remotely), MIDAS DAQ no longer working
|
DAQ server crashed around 24:00
Rebooted server but could not could not rescue remotely - could not contact raspberry pi in control of FEE bias.
Entered cave, rebooted raspberry pi. Would not accept remote connections. |

Tue Jun 10 09:44:20 2025, JG, MBS not running for a week
|
The MBS daq was not writing data since June 2. 22:39 (run_0035.lmd)
The reason is that the rfio server was running on atppc025 which crashed at that time.
We
resumed running MBS now at 10.06. ca. 10:35. (run_0036.lmd). |

This means, no detector and target timing is available for this period.

Thu Feb 15 13:18:30 2024, JG, MBS DAQ: target & ring values
|
We are running an MBS DAQ to record the attached list of slow control values of the ring and the target. In most cases this is achieved by converting
analog monitor voltages to frequencies and recording them with a VME scaler (VULOM4B with scaler-firmware). The complete list of signals is attached including
a channel mapping. |

When using the VITAR connected to the HDMI port of the root MACB the settings for all the MACB in the system 0x3.
This setting takes the Clock and Data line from the input HDMI and outputs it via teh HDMI output ports.
When using the Emulator connected via the SMA connectors on the back of the root MACB then the setting for the root MACB |

Sun Apr 30 10:01:39 2023, CB, JM, Left hand detectors unmounted 26x
|
(29 April)
Inspected CARME after opening. See attached. Some key takeaways.
- No visible damage to the detectors or the Kapton cables. No visible deposits or dust on the detectors either. |

(31 April)
Remounted 3335-12 on top and new 3335-1 on bottom of left hand plate. Used new dog legs and old standoffs.

Found two leaks in the welding of the manifolds, marked them in tape. Manifold to be repaired on Monday. Remember to re-install missing hoses, which
are in a bucket in the cave.
See attached how it is supposed to look like. |

Arrived at GSI in the afternoon.
Found that the coolant loop on aida08 had popped out which resulted in the high FEE temperatures observed (see attachment 1). Female swagelock |

Thu Jul 6 15:26:39 2023, JM, Leak update
|
The leak on the actuator arm bellows has been attempted to be sealed using UHV vacuum seal spray. The spray had the opposite to the desired effect and
the leak rate increased. When spraying with helium the leak rate had increased to 1e-9 mbar l/s. After lunch a second application of the vacuum seal spray
was attempted, however the leak was not sealed. The base leak rate had also increased to the 1e-10 level up from in the morning and yesterday. With the |
