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. |

Sat Jan 13 14:25:05 2024, CB, JM, Bias tests with all FEEs connected

Connected all FEEs.
The two top fees corresponding to the bottom right detector are connected to damaged flexi rigid PCBs. The top one is missing an pin that should
not be connected to anything, while the bottom one has a slightly cracked connector and is missing the top left pin. Spares should be in Edinburgh. |
|

After discussions with Davide, changed the holes in the FEE holders for the bottom-right detector to slots in order to slightly change the angle that
the FEE inserts into the flexi rigid PCB. This was sufficient, with some difficulties, to insert both FEEs into the flexi rigid.
Attempted to finally mount the last two fees, the top two for the bottom-right detector, which should have been very easy. Somehow managed to |

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. |
|
Wed Jan 10 10:22:41 2024, CB, JM, Some FEEs mounted - issues with Det#2 (bottom left)
|
Started mounting some FEEs. We ran into some mechanical issues due to the new ERNI connectors on the new flexi-rigid adaptor PCBs. Davide skimmed 6.5
mm off the edge with the groove (the groove is gone). This is suffiicent to support the flexi-rigid and in spite of our earlier concerns, the flexi-rigid
can be mated/un-mated with the FEEs without major alignment issues. |

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. |

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.

but still significantly above the leak rate from elog 141 of the CARME chamber on its own. Spraying helium, a leak is visible on the VAT gate valve on

The new MACOR strain reliefs on the (detector side) have been installed. See attached photos
The two pieces of MACOR are not fully closed but we are confident that the kapton wires are sufficiently clamped.
In order for the strain reliefs to be installed in the correct poisition, two nuts on the jacking plate of the cable harness had to be removed. |

Since yesterday evening, the bottom right detector was at -150 V. In the morning, the current was quite stable ~ 6.77 uA. The bias was switched off,
the foils opened, both of the detector arms were moved in and out three times, and the chamber was tightly covered again. A negative bias voltage was applied
from 0 to 150 V in steps of 10 V one by one to all four detectors, and the V-I results can be seen in Attachments 1-4. All detectors seem to be |

Today, the foil was opened, the pins on the bottom right detector were checked and looked fine, the right-hand arm was moved a bit in and then out, and
the foil was tightly closed again. The negative bias voltage was applied from 0 to 50 V in steps of 10 V. During the measurement, the lights in the cave

To test the detectors, adaptors were installed on the feed through flanges. A negative bias voltage was applied in steps of 10 V from 0 to 150 V. The
V-I plots are attached for the four detectors. Three detectors - top right, top left, and bottom left (in the direction of the beam) - are fine. For the
bottom right detector (in the direction of the beam), the current was fluctuating and was considerably high (1st test). The adaptors connecting to this |

In this last hour we have been playing with the cryostat temperature as dictated by Nikos, in order to have the target working properly. For this, we
have increased from 80K to 140K the cryostat temperature then we saw again target until we didn't. Then we went down again to 80K. After a few minutes,
with a really nice target again was gone, so we increased the temperature to 120K at 00:19. At 00:27 decrease from 120K to 80K. |

The length of the wire needed was estimated with the aid of a scale image of the detectors in the CARME chamber and foam model pieces. Wire length estimated
by simply cutting wire so that it 'fits' the scale model and by taking coordinates of the end points of the longest sections of wire needed on
the model and calculating a bezier curve to estimate wire length. Bezier curve calculated by inputting the endpoints of the wire and control points such |

10:10 Pressure on the chamber = 3.1e-8mbar. RE-72 temperatures are ~120-125C with set limits at 80C. D2000 temperatures are ~370C. D2000's reduced
from 60W to 30W and all UHV 1400s reduced to 50W each to cool both the chamber and the D2000s so that ion pumps can be activated.

I have (fingers crossed) got the baking stepping up nicely now. I have used some of the outer shell to act as a shield and to direct airflow towards
the front and back of the baking volume. I also moved the RE-72 thermocouples to a higher temperature region and replaced the broken thermocouples. The
program is on automatic mode and has currently stepped up to 40C with the max diff reduced to ~4C. |

While moving the baking octagon into position, the power connector became disconnected from the turbo pump. The pump controller provided the
warnings of connector failure and high pump load (probably due to it reading the frequency of the pump as 0 Hz when disconnected and thinking this was |

Cooling of baking volume finished over the weekend, attached are some plots of the bakeout test. Bakeout2.png is the thermocouple profile for the entire
period over the week. The heating in the first seven hours followed a nice linear rise of ~5C/hour, in the 7-40 hour period the heating rate slowed due
to an issue with our octagon average limiting the increase in the temperature. The period from 40-65 hours was due to the picologger heating up to unacceptbly |

The Chamber has continued to pump overnight and we have reached a pressure of 3.3e-6 mbar as of 10:15. Power cable for the hot cathode gauge was found. Gauge
did not give a reading so pin connections were checked, all is okay so it may be thepressure is still too high within the chamber, gauge was thus turned
off. I have attached the RGA from this morning which has increased accuracy so has been cleared up for most of the noise from yesterday. I have begun |

|
A pump cart and leak cart have been connected to the chamber via the top turbo at the back of the chamber. An air line has also been connected to the
valve to open/close it. The pirani gaige has also been replaced by a blank flange, a gauge on the pump cart can measure the pressure in its range. The
turbo fan and controller were set up and pumping was started after lunch. |

Bakeout test completed. Maximum temperature reached within baking volume was 120 degrees, with baking stopped by the program due to detection of
negative temperature gradients. Negative temperature gradients due to a couple of thermocouples becoming unsecured and moving to cooler part of baking
volume. Attached documents show temperatures of thermocouples. The colour of plots are linked (all of chamber temperatures are blue etc). Temperature |
