Jenne | Update | safety | Nitrogen bottle too hot - overpressured |
All of us in the control room / desk area heard a sudden whoosh of air a few minutes ago. It kind of sounded like a pressure washer or something. We determined that the northmost nitrogen bottle outside the front door was letting out all its gas.
It's a gazillion degrees outside (okay, only 91F, according to a google of "Caltech Weather"), and those bottles are in direct sun all day.
We are leaving the bottle as-is, since it seems like its has finished, and nothing else is happening. |

Steve | Update | safety | response to fried Sorensen |

Q and Steve will follow elog 10028 entry to prepare the vacuum system for safe reboot
|
Here's the sequence of the morning so far:
- I aligned the IFO (IR arms with ASS, X green with PZTs, PRM with PRMI locked on REFL33)
- I closed the PSL shutter, and went inside to align PRM and both ITM oplevs (all others were within 10urad of zero in both directions)
- While aligning those oplevs, I noticed the smell of burnt electronics. We tracked it down to the +15V sorensen in the rack nearest the PSL table
- I claim the precipitating event was PSL shutter activity. If I recall correctly, the seismic rainbow traces went bonkers around the same time as the shutter was closed. There is a Guralp interface in the rack powered by the failed sorensen, so this would explain the erratic seismometer signals correlated with the power supply failure. We will look into potential shorts caused by the shutter. (Steve looked up the PMC trans and Guralp DQ channels, and confirmed the temporal coincidence of the events.)
- We shut off all of the sorensens so that electronics were not being driven asymmetrically.
- Steve and I secured the vacuum system for computer reboots, as referred to in Steve's elog. Some combination of Jenne, Rana and Manasa shut down the control room computers, and turned off the watchdogs.
- Manasa and I moved Chiara inside, next to Mafalda, along with its backup HDs. It has been labeled.
- Booted up control room machines, they came up happy.
- FB and front-ends didn't need reboot, for some lucky reason. Watchdogs came back happily, oplev spots didn't move noticeably.
The IFO is still down, as the PMC won't lock without the rack power, and we haven't pinned down the shorting mechanism. We don't want the replacement sorensen to immediately blow when plugged in.
|
Smoking Sorensen could have triggered the smoke alarm!
Yesterday I called CIT Fire Protection Services very first to deactivate the sensors temporarily. The smoke alarm was turned back on right after the particle count dropped.
Their phone number is posted at the entry doors 104M and 104W as shown below.
