Experiment E12-06-110 (A1n) and E12-06-121 (d2n) are scheduled to run from Dec. 3, 2019 to May 6, 2020, with breaks for the X'mas shutdown and the target rotation.
 +
These two experiments focus on studies of the nucleon spin structure.

The ~2000 channels of drift chamber signals are discriminated and the times of hits on wires are recorded in fastbus crates located in each of the spectrometer huts.  These times are digitized with Lecroy 1877 multihit TDC's with a resolution of 0.5ns.

Common Hall C Training Requirements

NOTE: These are the commonly required training to access and run shifts in Hall C.

The formal requirements will be outlined in the Run Safety Documentation for your particular experiment.

Contact a spokesperson and/or the RC if you have questions.

  • Annual Security Awareness (GEN034) • Expires: Annually (January)
  • Physics Division Work Governance (SAF116kd) • Expires: Annually (January)
  • General Access RWP (SAF801kd) • Expires: Annually (December)
  • Oxygen Deficiency Training (SAF103) • Expires: Annually (24 months from date taken)
  • ES&H Orientation (SAF100) • Expires: Annually (24 months from date taken)
  • RadWorker 1 Written Test (SAF801T) • Expires: Annually (24 months from date taken)Must be taken on-site -- register well in advance if the Lab is still in a MedCon status!
  • Hall C Walkthrough (SAF112) • Expires: Never • Must be done at JLab during a down. Schedule in advance!

These are also required as long as JLab is in an elevated MedCon status due to the COVID-19 pandemic

Many courses are Web based and can be found on the JLab Training Page.

You can check your training status online.

Also, don't forget to register your visit at least 7 days prior to your trip:

The formulas and program should be kept in sync with the repository.

  • Formulas used for setting current of SHMS magnets during KPP
Magnet Formula
HB Current = 330.05*p - 3.1784*p^2 + 0.4018*p^3
Q1 Current = 222.4*p - 7.709*p^2 + 0.6684*p^3
Q2 Current = 3661*p/11
Q3 Current = 2434*p/11
