      • Set SHMS to 6.79 degrees, with all magnets ramped to zero
      • Jay Benesch will execute his beam deflection test plan
      • Shift workers will need to ramp SHMS magnets as directed by Jay (use -3.007 GeV/c settings)
    • 4.9 GeV
      • Set SHMS to 6.00 degrees, with all magnets ramped to zero
      • Jay Benesch will execute his beam deflection test plan
      • Shift workers will need to ramp SHMS magnets as directed by Jay (use -4.565 GeV/c settings)
  • Beam checkout
  • Items to be done as soon as possible at 3.8 GeV AND 4.9 GeV

SIDIS pt experiment E12-09-017 Fall 2018

SIDIS CSV experiment E12-09-002

CSV Fall 2018 Run Plan

Past run plans

Hall C Links

Hall C

Hall C is one of four experimental halls at JLab.

Hall C Computing.

Hall C in the Press.

Basic Equipment in Hall C

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

Scattering Chamber

  • The scattering chamber window on the SHMS side is 0.020 inches thick 2024-T4 aluminum.

SHMS Entrance Window and Vacuum vessel

  • The Horizontal Bender entrance window is 0.010 inches thick 2024-T3 aluminum.
  • The dipole exit window is 0.020 inches thick 5056 aluminum.

Target

Spring 2017 KKP run

Fall 2017 run

  • Logbook entry on the Fall target configuration which has links to file describing the targets and their thicknesses and a file with the mechanical drawing of the target ladder.
  • BeO target was replaced by the "halo" cylinder target. Logbook entry with drawing of "halo" cylinder target.
  • Drawing of target ladder with cryo cells and solid target ladder.
  • Drawing of cryotarget cell with 2.5inch diameter and 10 cm long (after using insert entrance window). Used for separate LH2 and LD2 cells in ladder.
  • Drawing of cryotarget with 1.6 inch diameter for 4cm cell.
  • Drawing of cryotarget with 1.6 inch diameter for 10cm cell.
