Primitive Banks

• HARDWARE
• Data from detectors
• TRIGGER TRIGGER_PHASE
• Trigger latch word, and live time of trigger
  supervisor
• Data in TRIGGER, and run number, phase
• EVENTID
• Run number, Event number, Timestamp, etc.

Reconstructed HYCALCLUSTER
Variable Comment Value
E Clusters energy (GeV) Sum of cluster cells energies
time Clusters time (ns)
x x position reconstructed with wiEi
y y position reconstructed with wiEi
z Distance target to hycal
x1 x position reconstructed with wialn(Ei/Et)
y1 y position reconstructed with wialn(Ei/Et)

9
Reconstructed PFLUX

• PFLUX is reconstructed from TRIGGER RIGHTTIME
  banks. It stores the status of the events.
  0good, 1bad.

10
Non-event banks

• SCALER bank and EPICS bank store the data of slow
  controls, which have not been acquired event by
  event, i.e. BPM, Beam position, Beam current,
  Temperature, etc.

Summary

• This is a document to interpret the configuration
  of data in PrimEx.
• The document will be sent to everyone soon.
• Comments and feedbacks are welcome.
