Work Permit Summary for 2016 October 4
Work Permit Date Description alog
6215.html 2016-10-04 15:43 Activity: Replace QPD library block parts with the newer version that is already in use for the Transmon QPDs. This will allow proper lowpassing of our normalization signals. 30214
6214.html 2016-10-04 10:11 Activity: add more memory to h1nds0. co-ordinate with Guardian reboot. 30205
6213.html 2016-10-04 09:03 Activity: Look at Fast I monitors for ETMY to see why we have 4000ct offset. May be missing one leg of differential input. Per FRS 6114  
6212.html 2016-10-04 08:32 Activity: Replace HV Kepco power supplies with new ME Industries high voltage power supply for the ITM ESD LN Driver.  
6211.html 2016-10-03 14:46 Activity: Replace binary card in SEIEY IO chassis. This is to address STS-2 remote centering not functioning. Front end and IO chassis will need to be restarted (FRS 4683). 30207
6210.html 2016-10-03 11:01 Activity: Remote access (ssh) to the Seismon computer in order to investigate on some issues with the Seismon code (missing EQs).  
6209.html 2016-10-03 10:41 Activity: Give tour to several professors from Beijing Normal University. completed on Tuesday, Oct. 4, 2016
6208.html 2016-10-03 10:33 Activity: Minor guardian bugfix upgrade 30180
6207.html 2016-10-03 08:54 Activity: Investigate elevated noise on various CPSs: Cycle ISI state, power cycle satellite racks, unplug/replug cards, etc to reduce noise in sensors, ITMX, BS, ETMY 30174
6206.html 2016-10-03 08:41 Activity: Update the calibration code on the DMT to gstlal-calibration-1.0.3-1 and restart hoft generation. 30202
6205.html 2016-10-03 08:22 Activity: Crane scissor lift out of trapped corner near BSC 4 and meat locker and LTS containers. The scissor lift will be placed near the 3 IFO storage racks in the west bay. This exercise will require a laser safe condition in the LVEA.  
6204.html 2016-10-03 07:49 Activity: Remove the socks and HEPA filters from the BSC cleanrooms over HAM1/2, HAM3, HAM4, and between the arms near the 3IFO storage area for cleaning. Vacuum and/or wipe roofs of the cleanrooms.  
6203.html 2016-09-30 13:56 Activity: Drive photographer for Science magazine down x-arm to site for photo oportunities done
6202.html 2016-09-30 11:50 Activity: Install a new build of the daqd fw on h1fw2. This is continued testing on the build of daqd that will be in the next tagged release. We want to test on h1fw2 as it receives the full data stream, but does not write its results out to ldas, so is a low risk site for testing on the production system.  
6201.html 2016-09-30 11:26 Activity: Remove Symantec Antivirus on Beckhoff computers h1ecatc1 & h1ecaty1  
6200.html 2016-09-30 10:46 Activity: Science Magazine photographer Bill Douthitt will be on site Friday Sep 30 to scout the site for locations to shoot for an end-of-year article on GWs and LIGO. He will shoot at dawn and dusk, potentially Sat Oct 1 - Mon Oct 3. Amber will chaperon on Friday, but Douthitt will potentially shoot dusk/dawn on the weekend from outside, without accompaniment, if we are satisfied he understands our constraints.  
6199.html 2016-09-29 13:40 Activity: increase h1nds0 memory to 48GB to be the same as h1nds1. 30071
6198.html 2016-09-29 08:52 Activity: Re-terminate bad pin on DB37 binary connector for the AS-C QPD whitening Chassis.  
6197.html 2016-09-29 08:51 Activity: Replace faulty power switch on h1lsc0 IO chassis. Front end and IO chassis will need to be powered down.
