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

this afternoon, because of the test on the electron beam drive in the ring in the next days,
I removed the scope and the desktop computer (but not the display) installed close to the ThomX optical cavity.
they have been stored in the "Viktor" ThomX optical room. |

Safety patrol instructions, posted by Ronic Chiche at ThomX igloo about utilities
|
If one needs to work with 3rd stage on the laser amplifier, one needs to make the safety patrol inspection before closing the bunker.
for that, it is mandatory to switch 2 keys on the "key board" in the control room, just before or just after the safety patrol :
- the THOMX key to 1 |

after finishing the controlled intervention, you just have to exit the bunker with the 2 keys and place them back in their location
then the controlled access (colored yellow) will turn to "access interdit" (red colored)
to terminate the closure of the bunker, you just have to turn the two key indicated in the previous image back to their original position. |

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". |

UPS installation and commissioning, posted by Ronic Chiche at ThomX igloo about cabling
|
Jean-Noel Cayla installed several days ago a Eaton 9PX 11kVA UPS inside the Igloo, outside of the ThomX bunker
and I asked him to place only 1 UPS plug on the wall close to the FP-cavity to supply only the NKT/OneFive oscillator and the Smaract laser cavity
motors. |

finally I installed the OneFive laser, the Smaract motors of the laser and the Arduino Peltier controller of the laser on the UPS plug.
the power "seen" by the UPS is 0W, perharps because the used power is below 100W.
the UPS says it can last 385mn (> 6h) in case of power shut down. |

I was able to lock back the FP-cavity.
at one moment, during the alignment optmization process of the infection mirrors of the FP-cavity, I had a huge misalignment moving Ma-Y motor.
I had to realign a lot this motor to get back to the standard power inside the FP-cavity. |
