• 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.
    Note: Submit this ECL elog entry at the end of your shift, as you cannot edit an ECL entry after posting/submitting.
  • Confirm that the "Active Alarm for Target Operator" page is functioning on "uva-nuc-02", as instructed in this page.
  • It is advisable to check the outside weather forecast (https://weather.com/weather/today) and communicates communicate with the Target Expert and the Run Coordinator if there is an extreme temperature prediction.
  • 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: 
  •  IMPORTANT!!!  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, then check the controller's front panel from the camera cameras (on CCP machine): the following image shows when the turbo-pump is working normally.

    and see whether you are seeing a blinking green light or any error message with the RED light (see the following imageimages), then mention it in the discord and immediately follow the steps on this page IVC and also call the Target Expert on Shift.
    
    On 09 Jun 2024 the high-cube pump was installed at NM3 and a camera was also arranged. So, check that camera and follow the instructions on How to restart the high-cube pump
    if you see the red light with an error message (see the sample image below)

  • 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 F:NM4LCWT1 goes above 100F or any of the QT[1-5]A and QT[1-5]B start to average over 105F (a few fluctuations over this are ok) then let the Target Expert know108F  then call MCR to ramp-down the KMag if it's ON.
    Go to https://e906-gat1.fnal.gov/data-summary/e1039/target-allv2.php and select F:NM4LCWT1 ,and F:NM4LCWT2
    Direct link to the LCW temperatures from the cold-head compressors: (see the bottom plots on this page) https://e906-gat1.fnal.gov/data-summary/e1039/target-par-preset/target-helper-2.php
    Follow the instructions on How to clear the coldhead compressor LCW temperature alarm
    Note: Running K-Mag affects these coldheads, so make sure to coordinate with the Shift Leader to ramp-down K-Mag if coldhead outlet LCW temperatures are approaching 100 F.
    
• 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.
  • Ensure to submit your completed Target Operator Shift Report
  • If the Shift Leader is absent, complete the "End of Shift" form in the ECL.
