Mon Nov 21 15:16:12 2022, Tega, Update, CDS, workstation upgrade
|
We are currently working on donatella workstation upgrade, which we are calling donatellaclone for now. After installing Debian 11, we install the
cds conda environment. This takes care of most of the requisite
packages except `dataviewer` and `burtgooey`. |
Thu Sep 29 03:43:20 2011, kiwamu, Update, ASC, wrong channel assignment on IPPOS
|
The channels for IPPOS had been assigned in a wrong way.
Because of this, C1:ASC-IP_POS_X_Calc corresponds to the actual vertical motion and C1:ASC-IP_POS_Y_Calc is for the horizontal motion.
We should fix the database file to get the correct vertical/horizontal corrdinate. |
Tue May 17 19:38:32 2011, kiwamu, Update, SUS, wrong connection on 1X5 
|
Today Steve was working around the 1X5 rack to strain relief the cable jungles and the jungle is now getting
less jungle.
During the work he disconnected and reconnected some cables. |
Fri Jan 23 16:33:27 2009, pete, Update, oplevs, x-arm oplev calibrations
|
ITMXpit 71 microrad/ct
ITMXyaw 77 microrad/ct
ETMXpit 430 microrad/ct
|
Mon Jul 18 17:07:12 2022, yuta, Update, LSC, x4.12 added to ETMX coil outputs to balance with ETMY
|
To balance the actuation on ETMX and ETMY, x4.12 was aded to C1:SUS-ETMX_(UL|UR|LR|LL|SD)COIL FM1.
OSEM damping filter gains, oplev loop gains, and alignment offsets were divided by this factor.
C1:LSC-ETMX_GAIN is now 1. |

|
We aligned and locked xarm for green.

Mon Aug 7 14:02:52 2023, Radhika, Update, AUX, xend AUX fully locking with Moku:Go  
|
Moku:Go used for full locking of green laser - OLTF to come
Picking up from where
Reuben left off, I used the Moku:Go in multi-instrument mode to replace the signal generator and uPDH
box entirely (Moku:Go setup shown in Attachments 1+2). The lock-in amplifier sourced the modulation for the PZT: 210.5 |

Thu Nov 15 21:52:48 2012, Den, Ayaka, Update, Green Locking, yarm locked 
|
We aligned and locked Y arm for green:
installed camera on PSL to monitor green transmission
aligned green path on the ETMY table to see the beam on the PSL
camera
misaligned ETMY and aligned ITMY to see reflected beam on REFL PD
installed green transmission PD on PSL
aligned |
Wed Dec 18 03:29:48 2013, Den, Update, LSC, yarm locked on mc
|
As a CM slow path test I locked free swinging yarm by actuating on MC length with bandwidth of 200 Hz. Crossover with AO is not stable so far.
I used xarm as an ool frequency noise sensor. MC2 violin mode is at 645 Hz, I have added a notch filter to LSC-MC2 bank. |
Sat May 17 14:48:06 2014, den, Update, PEM, yend sei isolation kit is set 
|
Yend seismometer isolation kit (elog 8461) hosts Guralp seismometer. I made a cable for inside
connection, assembled the kit and relocated the instrument from its previous position at the yend inside the kit.
Seismometer is connected to the readout box and running. |

Mon Apr 19 13:23:03 2010, josephb, Configuration, Computers, yum update fixed on control room machines
|
I went to Ottavia, and tried running yum update. It was having dependancy issues with mjpegtools, which was a rpmforge provided package.
In order to get it to update, I moved the rpmforge priority above (a lower number) that of epel ( epel -> 20 from 10, rpmforge -> 10 to 20).
This resolved the problem and the updates proceeded (all 434 of them). yum update on Ottavia now reports nothing needs to be done. |
Thu Mar 5 02:24:19 2009, rana, Configuration, Computers, yum.repos.d
|
I added the following repos which I found on allegra to megatron and then did a 'yum install sshfs' on both machines:
allegra:yum.repos.d>l
total 28 |
Tue May 5 09:22:46 2009, caryn, Update, PEM, zeros 
|
For several of the channels on the PEM ADCU, zeros are occuring at the same time. Does anyone know why that might happen or how to fix it? |
Thu Jun 7 12:49:50 2012, Jamie, Update, Computers, zita network configured
|
Added zita to the martian host table, and configured his network accordingly:
zita A 192.168.113.217
https://wiki-40m.ligo.caltech.edu/Martian_Host_Table
|
Tue Nov 12 21:50:01 2013, rana, Update, , zita network configured
|
I installed 'nfs-client' on zita (the StripTool terminal). It now has mounted all the shared disks, but still can't do StripTool since its
a 32-bit machine and our StripTool is 64. |
Wed Jun 6 22:25:05 2012, Jamie, Update, Computers, zita now running ubuntu 10.04
|
I'll finish the rest of the config to turn it into a full-fledged workstation tomorrow. |
Wed Nov 6 17:45:34 2019, gautam, Update, LSC, ~
|
Here is a comparison of the response of various DoFs in our various RFPD sensors for two different CARM offsets. Even in the case of the smaller CARM
offset of ~1kHz, we are several linewidths away from the resonance. Need to do some finesse modeling to make any meaningful statement about this - why
is the CARM response in REFL11 apparently smaller for the smaller CARM offset? |
