UPS installation and commissioning, posted by Ronic Chiche at ThomX igloo about cabling
|
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. |

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.

New valves cabling, posted by Ronic Chiche at Optical room about mechanics | vacuum
|
Today, Manu and Eric changed the cavity valves pressure system to open and close them.
during the lock of the OneFive+Amp or of the Koheras, we saw a very noisy PZT signal at 30Hz with increasing/decreasing amplitude very slowly.
this noisy signal was not seen at the begining of the experiment. |

New valve cabling and 30Hz noise PZT, posted by Loïc Amoudry at Optical room about lasers and optics | vacuum

The Pneumatic valves are still coming back to "close" position.
Now the air bottle is always "open" to keep the valves "open".
The 30Hz noise is still here. We tried to cut off all the air flows. It only decreased the noise intensity but didn't change its shape. |

new circuit breaker for the UPS, posted by Ronic Chiche at Optical room about cabling
|
A new circuit breaker has been installed today before the UPS to fix the shutdown issues we observed some months ago when too many devices are connected
to the UPS.
it has to be tested... |

The first part of the edge installation was on done by Yann and Ronic
- close the 2 valves of the cavity |

Operations before moving the optical table from the optical room to the Igloo.
— the cavity has been filled with clean nitrogen to reach ambient pressure.
— the two valves have been closed using 5 bar air pressure to properly clamp them. |
