A major upgrade of NOTCam has been planned for some time and we are finally able to start in November 2007. This includes:
---------------------------------------------------------------------------
Tue 20/11 Make sure that the old NOTCam BIAS still runs on the
elizabeth computer in the SB (JC)
Wed 21/11 Don't fill NOTCam with LN2 this morning! (TP)
Turn off the PTR as early as possible (TP)
Empty LN2 tank: alt 30 and rot-pos -40 to -90 (TP)
Dismount NOTCam (PB)
Dismount the PTR rotary valve (PB)
Pack both rotary valves and bring to SLO (PB, TP)
Thu 22/11 Clean up in the "clean room" (PB)
Transport NOTCam to SB (PB, JT)
Connect to network in SB to monitor temperatures (PB)
Fri 23/11 Ship both rotary valves to Japan (PA, AD)
Calculate the dew point based on the humidity,
See Temp v Humidity graph at bottom of page.
e.g. If Ambient temp = 20oC and RH = 26% then
the detector needs to be warmer than 0oC
to open.
Prepare bearings with new MOS-2 spray (CP)
Open NOTCam if detector(!) is warm enough (CP)
Sat 24/11 Open NOTCam if detector is warm enough now (CP)
Set the charcoal getter to baking (CP)
Examine interior of vessel for metallic dust (CP)
Measure dimensions of the large vessel O-ring (CP)
Exchange of bearings (CP)
Test all new bearings (CP)
Sun 25/11 Take out the engineering grade array (GC)
Exchange PCB and test electronics (GC)
Install the bare multiplexer (GC)
Test NOTCam warm with new PCB and multiplexer (GC)
Use elizabeth computer in SB with old NOTCam BIAS (GC, AD)
If all OK, install Eng. Grade array (GC)
Warm test of Eng. Grade array (GC, AD)
Clean NOTCam inside (AD)
Remove the metallic dust grain on the WF camera (AD)
Measure available space in stop wheel entries (AD)
Tue 27/11 Deadline to close NOTCam and set to pumping (GC, PB)
Connect network for pressure/temp monitoring (GC)
Wed 28/11 Transport to dome and continue pumping (PB, JC)
Connect temperature monitoring (JC)
Make sure there are 3 full LN2 bottles for tomorrow (PB)
Thu 29/11 Start filling (from warm!) with LN2 and keep on filling (PB)
NB! Open side ports. Will need ~ 100 liters.
Get more LN2 (PB)
Fri 30/11 Fill LN2! Note! We have no PTR running! (PB)
Start the temp. email alerts when cold enough (AD)
Sat 1/12 Fill LN2 in NOTCam (CP)
Pump ALFOSC (CP)
Sun 2/12 Fill LN2 in NOTCam (CP)
Fill ALFOSC (CP)
Mon 3/12 Dismount SOFIN (II?, CP)
Mount NOTCam early (CP)
Daytime tests, darks, detector QC, alignment (AD, GC)
The result of these tests determine which path to follow:
1) If PCB OK, continue with night time observing (AD, CV)
At the end of the night empty NOTCam of LN2 (AD, CV)
NOTCam will be opened for installation of Science Array
2) If PCB not OK, empty NOTCam of LN2 and dismount it (AD, CV)
Mount ALFOSC and do service observations (CV, AD)
NOTCam will be opened to go back to old PCB
Tue 4/12 If not already done, dismount NOTCam (PB, GC)
Transport NOTCam to the SB (PB, GC)
If not already done, mount ALFOSC (PB, HU)
From here and onwards the schedule follows different paths.
--------------------------------------------------------------------------
Plan A: If the tests on 3/12 showed that the new PCB worked well and cured
the dark current problem, and there are no new problems related to it, then
we want to install the Science Array and have NOTCam cold for the tech night
13/12.
Fri 7/12 NOTCam should now be warm enough to open it (GC, PB)
Set the charcoal getter to baking (GC, PB)
Install the Science Array (GC)
DETNAME and CCDNAME will not be changed today, so set
COMMENT1='DETNAME=9-405R-A1 #244 CCDNAME=SWIR3' (AD)
Warm tests of the Science Array (GC, AD)
Close NOTCam and set to pumping (GC, PB)
Connect to network for pressure/temp monitoring (GC)
Change output database for the QC to Science Array (AD)
Mon 10/12 Transport NOTCam back to the dome (CP, PB)
Continue pumping and connect temp monitoring (CP)
Arrange to have 3 full bottles of LN2 for tomorrow (PB)
Tue 11/12 Check that vacuum is OK (PB)
Fill slowly (!) with LN2 (open sideport!), start early (PB)
Continue filling all day, takes ~ 100 liters (PB)
Get more LN2 (PB)
Wed 12/12 Fill NOTCam as often as needed (CP, TA)
Thu 13/12 Dismount ALFOSC and mount NOTCam (PB)
Fill NOTCam with LN2 (PB)
Change database to qc_notcam*_sci in analysing scripts (AD)
Set COMMENT1='DETNAME=9-405R-A1 #244 CCDNAME=SWIR3' (AD)
Daytime tests, alignment, detector QC, lamp QE (AD)
The result of these tests will decide:
1) If OK, continue with night time commissioning (AD)
2) If not OK, dismount NOTCam and let it warm up (AD)
Mount ALFOSC instead (AD)
If Science Array is OK, keep NOTCam cold by filling with LN2 every
day until we get the PTR rotary valve back! If not, plan C (see below)
must be followed to get the eng. grade array back in and NOTCam cold
before the January 17th visitor run.
Fri 14/12 Dismount NOTCam and mount ALFOSC (PB)
Mon 17/12 Mount PTR rotary valve when it arrives (PB)
Start the PTR and check that it works (PB)
Keep NOTCam cold trough Christmas and New Year!
Tue 8/1 Set DETNAME='9-405R-A1 #244'/CCDNAME='SWIR3' fits headers (JC)
Put new readnoise and gain values in NOT2MEF (JC)
Put new rotation centre values in NOT2MEF (JC)
---------------------------------------------------------------------------
Plan C: If the Science Array failed and we have to go back to the Eng. Grade
Array (but with the new PCB).
Fri 14/12 Let NOTCam warm up (PB)
Mon 7/1 Transport NOTCam to the SB (PB, CP)
Open NOTCam in the clean room (PB, CP)
Set the charcoal getter to baking (CP)
Tue 8/1 Change back to the engineering grade array (GC)
Set DETNAME='8-344R-#1 #131'/CCDNAME='SWIR1' fits headers (JC)
Close NOTCam and set to pump (CP, GC)
Connect to network for monitoring (CP)
Thu 10/1 Transport NOTCam to the dome (CP, PB)
Set to pumping and connect network for monitoring (CP, PB)
Fri 11/1 If vacuum is OK, start the PTR (PB)
Mon 14/1 Fill NOTCam with LN2 and keep refilling (PB)
---------------------------------------------------------------------------
In all cases continue as follows:
Tue 15/1 Fill NOTCam with LN2 (PB)
Wed 16/1 Mount NOTCam for tech night (PB)
Tech night tests (AD)
Update all documentation (AD)
Thu 17/1 First visitor run after upgrade (AD)
