| 6085.html | 2016-08-15 19:29 | Activity: Install a new copy of the daqd frame write software on h1fw0. This build of the frame writer includes some enhancements to help address stability. Issues and some expand diagnostic channels which may be put into the frame. | |
| 6084.html | 2016-08-15 17:21 | Activity: Install new ISS software to support testing of new outer loop chassis. Will require restart of all models to reallocate DAC chans. New binary IO card will be used. Fast chans added to commissioning frame. DAQ restart needed. Area of Activity: PSL front end software | 29139 |
| 6083.html | 2016-08-15 17:12 | Activity: Swap the CO2 laser on the TCSy table for a spare; align the new laser to the original beam path. The TCSy CO2 laser had a power drop from ~55W to ~40W. The RF driver was swapped and now the laser is only outputting ~15W, therefore we are now swapping the laser to return to ~55W operation. The TCSy table will be opened and a 50W Class IV CO2 laser will be operating, therefore this will require the LVEA to be in LASER HAZARD. | |
| 6082.html | 2016-08-15 15:59 | Activity: Start and run locally mounted turbo backed by pump cart and scroll pump at Vertex RGA * Bake RGA while isolated from Vertex volume and with calibration gas isolation valves open. Area of Activity: Vacuum, Vertex RGA, LVEA | |
| 6081.html | 2016-08-15 14:43 | Activity: Install new ISS servo. As planned at the moment install the new servo in the PSL racks. Extend the Photo Diode cable from the Ham chamber to the Rack. Connect the new servo to IO system. Make software changes as needed test. Area of Activity: PSL ISS outer loop Servo | |
| 6080.html | 2016-08-12 18:13 | Activity: Isolate and remove locally mounted turbo pump from RGA pump port * Install 1 1/2" O-ring valve in place of removed turbo * Pump out volume between pump port valve and O-ring valve - Close O-ring valve * Open 2 1/2" RGA isolation valve and expose RGA to Y-end volume * Energize RGA filament and start continuous scanning * Stop scanning at the end of the day and de-energize filament * Leave RGA exposed to Y-end volume (new "nominal" state). Area of Activity: Vacuum, RGA, Y-end | |
