** Use HMS pion collimator and SHMS collimator.

** Start with 30uA on lower 6% Carbon, after a 2 hr run, increase to 40 uA and after another 2 hr run move to the upper 6% Carbon and ask for 50 uA.

** Keep track of good coincidence physics events (with tight PID cuts and coincidence time cut) such that we have 10000 events for LH2 and Carbon

Current/Running Experiments

EMC and X>1 Experiments (E12-10-008/E12-06-105)

The inclusive electron scattering cross-section will be measured for several light to medium heavy nuclei over a broad range of x (0.1 < x < 1) and at x greater than one (x > 1).

12 GeV Data Summaries

Pages summarising measured data for various purposes in the 12 GeV era are listed below -

Note that this is a work in progress as of the 23rd of January 2023.

Hall C

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:

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:

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

SHMS Survey Data

SHMS Collimator/Sieve

  • The SHMS collimator/sieve assembly is located between the Horizontal Bender and the first quadrupole.
  • The SHMS collimator/sieve are made of Mi-TechTM Tungsten HD-17 (Density 17 g/cc. 90% W, 6% Ni, 4% Cu).
  • The SHMS collimator is a flared octagonal aperture with thickness of 2.5 inches.
  • There are two SHMS sieves. Each with thickness of 1.25 inches.
  • The sieves have the same hole pattern but one sieve has the hole pattern horizontally shifted by half the hole spacing.
  • Drawings of the collimator and two sieves.
  • The drawings show details of the sieve hole patterns and the collimator shape.

HMS Collimator/Sieve

  • The HMS collimators/sieve assembly is located in 166.4 cm from the target in front of the first quadrupole.
  • The HMS collimators/sieve are made of Mi-TechTM Tungsten HD-17 (Density 17 g/cc. 90% W, 6% Ni, 4% Cu).
  • The HMS collimators are both a flared octagonal aperture with thickness of 2.5 inches.
  • There are two HMS collimators which are designated as the "larger" and "small" collimators.
  • Drawing of the small collimator. It is labelled as the "top" collimator in the drawing. The "center" collimator is the drawing was replaced by the present day large collimator.
  • Could not find a drawing of the present day large collimator.
    • The dimensions are front (back) opening in the horzontal direction are 4.575cm (4.759cm) along top of octagon and 9.150cm (9.518cm) at the vertical middle of the octagon.
    • The dimensions are front (back) opening in the vertical direction are 11.646cm (12.114cm) along side of octagon and 23.292cm (24.228cm) at the horizontal middle of the octagon.
  • The HMS sieve has thickness of 1.25 inches.
  • Drawings of the sieve.
