This afternoon, we continued to clean the housing with Manar and Daniele.
we did a dust measurement after cleaning with the two ceil doors opened and the dust meter in the middle of the table, and it counted ZERO!
it doesn't mean the housing is perfectly clean but it is clean enough to pay attention now to cleanness. |

We observed 2 issues for the chiller of the new CELIA laser amplifier:
setting the water temperature to 17°C, the chiller water turns to ice close to the water filling port !!! => temperature too low
?
even when the water is fluid, one has a flow sensor error ! => pump charge too strong ? => reduce the water pipe length.

Today, the chiller worked at 17°C during 3 hours without error, no freezing nor flow sensor error.

Chiller installation + interlock, posted by Ronic Chiche at ThomX igloo about mechanics

- this morning with Aurélien, we filled the water tank of the chiller and we opened the water valves (last pipes on water arrival/departure panel).
there is no leakage on the external water circuit but there is a small one on one of the Swagelock adapters of the water circuit connected to
the Alphanov Amplifier. |

- this morning the chiller leakage has been fixed by adding some Teflon on the faulty Swagelock adapter.
a long leakage test has to be done to be sure there is no leakage at all => can be done on Friday during our tests.
- here is a picture of the 2 Alphanov amplifier controller interlocks. |

This morning, I started the chiller and opened the valves on the external water circuit => no water leakage during the morning.
now, the chiller will stay ON all the time => we will check the installation at the end of the afternoon.

Airflow power breakdown, posted by Ronic Chiche at ThomX igloo about utilities
|
since around 2 weeks, the airflow above the optical table housing has a power breakdown when one tries to switch it on.
the power breaker is in the electrical bay, on the left of the south entrance of ThomX.
the name of the power breaker switch related to the airflow is "TABLEAU ANNEAU 4". |

Airflow installation, posted by Ronic Chiche at ThomX igloo about mechanics

On the 27th of May, the Airflow has been dismounted from the optical room to be mounted around the optical cavity by the AirC2 company.
here is email from Yann :
Le flux est rentré dans la casemate. |

The AC plug and the power cord of the airflow were quite hot because they have been dimensioned for 16A current and the total current is above.
AirC2 company should replace them with 32A equipment (6mm2 power cord + 32A Hypra AC plug) in the next days.
