- Cover the IGRINS entrance window
- If the calibration unit is still on the cryostat, close the calibration unit slide window
- Otherwise, place the metal cover over the cryostat entrance window
- On the ICC shutdown the DTP, QLP, and SCP. It is useful to keep the HKP running for temperature monitoring and logging.
- Home the calibration motors:
- Open a terminal window and type “cd ~/igrins_admin”
- Close the HKP
- Type “python mtini.py”, it will ask to close HKP.
- Follow the commands of that program to home each motorRestart the HKP after completionhome the motors (select "0" to initialize then "5" to exit).
- Detector Shutdown:
- Using “Remote Desktop Connection” log onto each of the three detector computers to shutdown the detectors and Jade2 cards.
- IP Addresses for each computer are listed here:
- SVC: 192.168.2.4
- H: 192.168.2.5
- K: 192.168.2.6
- When logged into Windows navigate to the “HXRG Testing Software” window.
- In the top left panel, press the “RESET ASIC” button. This will grey out most of the other options on the panel.
- In the top left panel, uncheck the “ASIC Main Power” box to power down the detector.
- Close the “HXRG Testing Software” window
- Navigate to the “HalServiceApp” window.
- Press the “Stop” button.
- Close the “HalServiceApp” window.
- Using the Windows Start menu shut down the computer. Answer the question regarding shutdown.
- IP Addresses for each computer are listed here:
- Using “Remote Desktop Connection” log onto each of the three detector computers to shutdown the detectors and Jade2 cards.
- Computer Shutdown:
- The IGRINS DSC will normally be left running at all times, but if you need to shut it down:
- On the ICC, open a “Remote Desktop Connection” to 192.168.2.1
- Once logged into the DSC, shut down the DSC with the normal Mac OSX shutdown command.
- Unless necessary, leave the ICC and HKP running to maintain temperature logging during warmup. Otherwise, shutdown the ICC using the normal Mac OSX shutdown command
- The IGRINS DSC will normally be left running at all times, but if you need to shut it down:
- Instrument Disconnect:
- Turn off the helium compressor by flipping the white and yellow switches to the off position. This will stop cooling IGRINS.
- Wait at least one minute to release latent heat from the helium and then turn off the recirculating water chiller and the coolant booster pump.
- Remove the He flex lines and cover the ends with dust caps.
- Remove all electrical connections from the calibration unit
- Three Ethernet motor controllers
- Two locking power cables
- One locking circular connector
- MAKE SURE THAT THE JADE2 CARDS HAVE BEEN TURNED OFF IN SOFTWARE BEFORE PROCEEDING!
- Remove the Ethernet and power cables from each of the Jade2 cards.
- Turn off the main power to the electronics box and secure all remaining cables to the box.
- Remove the orange IGRINS fiber connection from the network switch in the electronics box.
- The calibration unit may be removed or left on the cryostat at this time.
- The shutdown procedure is now complete and IGRINS can be stored. Refer to the other notes on opening in the lab and transport.
