| 6174.html | 2016-09-20 17:00 | Activity: Bug fix to Time Dependence calculations; must pick off SIN/COS output of oscillators for excitation injected just upstream of DARM filter banks (which determines the actuation strength of the ETMY's). Change to h1calcs front-end model alone. Requires a DAQ restart. | 20853, 29852 |
| 6173.html | 2016-09-20 10:52 | Activity: h1fw2 has the rcg3.2 daqd code with additional EPICS diagnostics channels. These need to be added to the DAQ (H1EDCU_DAQ.ini). DAQ restart needed. | 29852 |
| 6172.html | 2016-09-20 10:31 | Activity: Remove old second loop ISS; rename outerloop to secondloop. Copy over QPD & REF. | 29854, 29852 |
| 6171.html | 2016-09-20 09:52 | Activity: clone h1fw1, run h1fw0 with the cloned disk to make the two frame writers identical. Will require NDS restarts as we swap between frame file systems. | 29852 |
| 6170.html | 2016-09-19 16:21 | Activity: Investigate clipping of PCal beams. This will require an aligned ETMx and the end station will be transitioned to Laser Hazard. | |
| 6169.html | 2016-09-19 14:46 | Activity: Install interlock to prevent pump from restarting after power outage. This is to mitigate a problem with the pump running backwards after brief power glitch. | |
| 6168.html | 2016-09-19 10:46 | Activity: reuse two spare filermodules for PWR-EOM data. install additional PWR filters. DAQ change to replace in commissioning frame the 2 spare with 3 pwr_eom at 2kHz. DAQ restart required. | 29797 |
| 6167.html | 2016-09-19 10:08 | Activity: Lower flow through the PSL HPO in an attempt to mitigate increased pointing noise (especially around 1kHz). | |
| 6166.html | 2016-09-19 09:38 | Activity: Update h0vaclx to remove PT140 gauge pair. This has been replaced by a BPG402 gauge. Requires DAQ restart. Will trip ITMX and HAM6 HV supply. | 29794, 29835, 29839, 29852 |
| 6165.html | 2016-09-16 14:47 | Activity: Replace a generic interface box (D1002932) with a whitened version of the generic interface box in order to improve the signal-to-noise ratio for the intensity monitors. The box sits under the PSL table, and therefore the person needs to enter the PSL booth. | |
| 6164.html | 2016-09-16 08:59 | Activity: Set h1brsex and h1brsey to autostart the Beckhoff PLCs, C# code and EPICS IOC. Test through restarts. | 29832 |
| 6163.html | 2016-09-16 08:32 | Activity: Host tour for vacuum/NEG pump vendor visitor to either EX or EY, which ever is less intrusive. Start around 9:45am and should last no longer than 15-20 min. | |
| 6162.html | 2016-09-15 17:20 | Activity: upgrade h1hwsex computer from U10.04 to U14.04 | |
| 6161.html | 2016-09-15 15:52 | Activity: Continue development on the MEDM to html converter. This is to improve the current screens and prepare more for presenting it at the EPICS meeting next week. This will likely involve minor outages of the screens that are reflected in realtime over lhocds (not the remote medm commands) which are used by the vacuum and facilities group. This will require remote access to CDS. | |
| 6160.html | 2016-09-15 14:45 | Activity: Edit h1susprocpi to save 64 channels to science frames at 2048 (32 BP_IN1 and DAMP_32 OUT). Edit PI_MASTER > IWAVE_PLL_BY_MODE to add EpicsIn 'State'. The latter will allow user input to set a state for each mode that guardian can then read to determine if mode should be handled by guardian or not. | 29739 |
| 6159.html | 2016-09-15 08:50 | Activity: Swap ion pump controllers. Remove ion pump controller from x-end and install at x-mid. Install removed controller from x-mid at x-end. | 29729 |
| 6158.html | 2016-09-14 14:17 | Activity: Fix the ISS arm power scaling for the third loop. Requires updated LSC and ISS front-end models. | 29701, 29732 |
| 6151.html | 2016-09-12 11:54 | Activity: GC core router will be rebooted and have transceivers swapped to upgrade from 1Gb to 10Gb connection with ESnet. Wireless and Internet connectivity will be disrupted during the short outage. CDS and LDAS internal networks will be unaffected, along with the phone system. | 29829 |
| 6105.html | 2016-08-19 14:44 | Activity: Pull EtherCAT End Station Chassis 3 at EY and EX. Will inspect cabling for the Demod readbacks for the green WFS. Fault Report 6024 | 29848 |
