- Beginning of shift
- Arrive at NM4 at least five minutes before the start time of your shift. Take over the status and the plan of the target system from the outgoing shifter.
- If the Shift Leader is absent, call MCR (x3721) and say something like "This is <YOUR NAME> at SpinQuest (NM4), and we are starting a new shift." The MCR person will thank you.
- If the Shift Leader is absent, complete the "Beginning of Shift" form in the ECL elog.
- Complete the Target Operator Shift Report : ← copy this table to your ECL elog entry and fill it out.

- Power Outages can be very hard for the cryogenic system to recover from. If you are aware about an upcoming power outage, or having an outage or even a power flicker,
then let the Target Expert know immediately.
- Frequent checks:
- Is the Internal Vacuum Chamber (IVC) good and at pressure below 10-6 Torr (spikes above 10-5 Torr for a few seconds during filling are OK, but if it takes longer than a few minutes to come back down, call the Target Expert.
- Is the Liquefier producing normally without any alarms (RED lights indicating alarms on the QT screen) and are the cold head compressors all running (green light)? If there is an alarm or the coldhead indicators are RED, then call the Target Expert.
- Check whether the magnet is ramped up. Is there any sign of a target magnet quench? If it is and at some point you see the magnet pressure shoot up to 9 psi in a few seconds, call the Target Expert immediately. The magnet control VI will also indicate a quench.
- What are the LCW temperatures? If
- Every hour
- Confirm that all computers/programs are running (not got stuck), including the QT HMI screen, the PDP screen, the target computer, the microwave+lifter computer, "uva-nuc-01" and "uva-nuc-02".
- Check all strip charts and communicate with the Target Expert immediately if you notice anything unusual: especially IVC, LCW flow, LCW pressure, LCW temperature, LCW temperatures on QT compressors
- On-demand
- Manipulate the Microwave Control system in case of the "Production" mode.
- Respond to all target-related alarms, as instructed in this page.
- End of shift
- Hand over details to the incoming shifter.
