Line 85: Line 91:
 Go into lab building, check pressures on Vacmon display. If pressure is higher than 100 torr in any of the lines, pump those lines only one at a time. Open valve a little, then come back to open fully. When all lines to be used are well below 100 torr, open all those valves. The final pressure should be 0.5 - 1.0 Torr in each line. The pump will normally bring all 6 lines down to .2-.3 Torr. The S1 and S2 lines leak the most during the day and will read the highest in the afternoon when you return, usually around 10 and 20 Torr. Note any unusual vacuum readings as they can indicate a leak beyond what is normal. Sometimes a line isn't pumped down the night before and can read higher than 30 Torr. Pump the highest ones down first as stated above. Go into lab building, check pressures on Vacmon display.

 Fill both chambers on the NIRO camera. Use the gloves and glasses provided on the shelf with the funnels and the thermos. It will normally take 1 liter of LN2 in the outer chamber and 1/2 liter in the inner chamber. Fill it until the LN2 bubbles out of the top. This camera is normally kept cool all the time, exceptions will be noted.\\ Fill both chambers on the NIRO camera. Use the gloves and glasses provided on the shelf with the funnels and the thermos.

-Clear the job queue on Cosmic Debris. Press the [END NIGHT] button on Cosmic Debris. This will close all the shutters, stow the active telescopes, close the telescope mirror covers, send the OPLE carts to the back switch, close the OPLE socket, and archive the accumulated data for the night. NOTE: The End Night Sequence will NOT close the dome slits so these will have to be closed manually after all of the telescope M1 mirror covers are closed. It will also not send inactive carts back. Update the configuration with any inactive scopes to make sure those carts can be sent back manually as well. The Cosmic Debris status window will indicate when the end night sequence is complete. You can close Cosmic Debris after you have sent out the Observing Report. * If you use the End Night sequence to stow the telescopes and close mirror covers, remember to do a visual check of all telescopes using the check list in step 6.4 below before turning off the power for the telescopes and closing the telescope GUIs.\\+Clear the job queue on Cosmic Debris.

 A list of observed targets and an Observing Report is now automatically generated as part of the End Night Sequence. Click [END NIGHT], then [REPORT] on Cosmic Debris to generate this automatic report email. The report will include the headings: PI name, Program, Observers, Baselines, Weather and Seeing data, and targets on which data was collected. Complete the Observers and Baselines entries, add comments to the bottom of the report and put your name at the end. Check with the observer for completeness of the target list. Some observers will send you comments of their own. Add those to the report. Cut and paste this into an email to CHARA Obs and send it. When the function works, you can also hit the SEND button at the bottom of the report to email this report to the CHARA OBS list.\\ A list of observed targets and an Observing Report is now automatically generated as part of the End Night Sequence.

-Unlock the tiptilt beams using the Tiptilt servo control GUI. Turn the telescope TVs to SPY1 so that you can watch the telescopes and domes stow. On the Control Tab of the telescope GUI, click [STOW]. This will send the telescope and dome to the stow position. When the telescopes reach an elevation above 50 degrees, you can begin closing the mirror covers. M1 CLOSE, M3 CLOSE, M5 CLOSE, M7 CLOSE, Finder CLOSE Note that W2 and E1? finder covers need a second click to close. Visually inspect the telescopes using SPY2 to make sure that the mirror covers close properly. Check the Telescope Monitor for mirror cover status. After the M1, M3 and finder mirror covers finish closing, close the dome slits by clicking [SLIT CLOSE] on the telescope control tab for each telescope dome that is open. Close the dome enclosures by clicking [CLOSE] on the cylinder GUI. Watch that each reads .000 or .001 when closed. Check that the telescopes moved to their stow positions in EL and AZ: EL 90.0 deg, AZ 55.9 deg for E1 and E2, EL 90.0 deg, AZ 99.3 deg for W1 and W2, EL 90.0 deg, AZ 82.0 deg for S1 and S2. Turn off the power for [TEL AZ], [TEL EL] and [TIP/TILT] for the active scopes using the Power GUI. Visually check all telescopes in the spycams to make sure all covers and slits are closed. Leave the telescope GUIs open until the End Night Sequence is finished. (Cosmic Debris will turn on the TVs and the SpyCams during the End Night Sequence.)
