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
- SAF003 training: Working Safely at Jefferson Lab During Elevated MedCon Levels
- ESH-20-102494-OSP: COVID-19 Pandemic Controls (READ NOW, sign copy in CH when you arrive.)
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:
Recommended Mailing Lists
Recommended Mailing Lists JLab runs many Mailing Lists to communicate with its Staff and Users. Most are available for general sign-up by clicking on the relevant link and following the instructions.
There are a few Mailing Lists that Hall C Users are strongly encouraged to subscribe to:
There are also experiment specific Mailing Lists. Contact the Experiment Coordinator if you do not see yours here:
Basic Equipment in Hall C
Beam Energy
Beam Current Monitoring (BCM)
Beamline
SHMS Magnets
For the Fall 2017 run, see intructions at https://hallcweb.jlab.org/wiki/index.php/How-to
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 |
Dipole | Current = 3450*p/11 |
