| 6119.html | 2016-08-23 22:37 | Activity: GC core router will be removed and replaced. Wireless and Internet connectivity will be disrupted during the short outage. CDS and LDAS internal networks will be unaffected, along with the phone system. * New equipment will be racked ahead of time (non-disruptive) * New cabling will be run ahead of time as needed * Cisco 6504 will be left on (for ease of rollback) * External optical taps will be removed (too lossy at 10Gb) * External and internal connections from the Cisco will be moved to the new routers * Internal links will be brought up and internal traffic will be checked (flows between wireless/wired) * External link will be brought up and routing tables will be checked. Area of Activity: GC core router and Internet connection | ||

| 6112.html | 2016-08-22 16:11 | Activity: Replace broken water cooled power meter in HPO. The power meter did not survive the June power outage. This is the power meter in the HPO's external shutter assembly; power meter can be swapped in situ, external shutter assembly removal is not required. The PSL and its chillers will have to be shut down for this work. | 29270 | |
| 6111.html | 2016-08-22 16:02 | Activity: Energize RGA and take post-bake scans to assess effectiveness of recent bake * Combine RGA volume to Vertex Vacuum Volume if applicable * Decouple locally mounted turbo pump from RGA and install 1 1/2" O-ring valve in place of turbo (requires venting one side of metal valve which isolates turbo from Vertex Vacuum Volume * Pump to rough vacuum volume between newly installed O-ring valve and existing metal valve * Shut down pump cart | 29194, 29196 | |
| 6110.html | 2016-08-22 15:53 | Activity: Take Asahi Shinbun staff to the site tour. We'll enter LVEA in the morning and will stay there for less than an hour. | ||
| 6109.html | 2016-08-22 15:46 | Activity: Tour PNNL and visiting physicists through site and LVEA. We expect to be in the LVEA for 30min starting approximately 10am, on Tue 23rd. | ||
| 6108.html | 2016-08-22 15:22 | Activity: Change pre-filters on AHU-2. | ||
| 6107.html | 2016-08-22 15:17 | Activity: Flow test and zero count all dust monitors in LVEA, Diode Room, Optics Lab and both end stations. Have already tested the PSL dust monitors. Do Not need to get into the PSL enclosure. | ||
| 6106.html | 2016-08-22 14:18 | Activity: Install conduit from mechanical room to air handler rooms, pull control wiring and install electric actuators at AHU 1,2,& 3. | ||
| 6105.html | 2016-08-19 21:44 | 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 | ||
| 6104.html | 2016-08-19 20:12 | Activity: Install 200 kHz pole optional daughter board into IMC PDH Common Mode Servo Board (D040180). See LHO aLOG 28363. Should not take more than an hour. | 29250 | |
| 6103.html | 2016-08-19 18:05 | Activity: Valve in 500 L/s ion pump and valve out turbo pump. Pressure is currently at 1.1e-6 Torr (new gauge). Pressure will initially rise; after pressure reduction is observed, we will power down turbo and backing scroll pump. | 29206 | |
| 6102.html | 2016-08-19 16:28 | Activity: upgrade h1dmt0 to SL7, as requested by John Zweizig | ||
| 6101.html | 2016-08-19 13:55 | Activity: Replace Beckhoff temperature module 3202. One channel has been failed since installation. This is the link chassis so all of the Beckhoff will be disconnected. | 29200 | |
| 6100.html | 2016-08-19 12:03 | Activity: Make corrections to the FSS front end model. The corrections are related to the temperature readouts for the reference cavity. Currently these do not reflect the hardware in place. This work will require a restart of the FSS front end model and a DAQ reboot. | 29229, 29197 | |

| 6093.html | 2016-08-17 15:45 | Activity: Swap CO2 laser RF driver on TCSx table and measure the output power of the TCSx CO2 laser. We want to test if we have a bad RF driver from the TCSy laser, and the best way to do that is install the RF driver into a working system and see if the output power changes. Once complete we will reinstall the original TCSx RF driver to return the TCSx CO2 laser to normal operation. Risk to the TCSx CO2 laser is low. | 29174 |
