Hall C 12GeV Upgrade

NEWS ABOUT SHMS DESIGN

Single arm SHMS Monte Carlo has be updated

Note that for simulations for upcoming 12 GeV PACs, one should assume the "standard" 10 cm, 20 cm, and 30 cm cryotargets will be available. Please note that the total beam current available for Hall C and Hall A together will be 85 micro-amps (11 GeV equivalent).

CURRENT SHMS STUDIES AND R&D

• Hall C 12 GeV experiments and requirements    
  To date, the 12 GeV PAC has met six times and fully approved 15 experiments, 11 of which are graded, for Hall C.  Experiment proposals submitted to PAC30 (2006), the proposals submitted to PAC32 (2007) , and the proposals submitted to PAC34 (2009)

• Hall C 12 GeV Document Database (including official figures, password required) The document database contains all documentation associated with the Hall C 12 GeV upgrade including detector and SHMS R&D work. The Hall C Public Document Databaselists public interest Hall C and 12 GeV documents. 

• SHMS Beam Envelope 
  The beam sizes at different z-locations in the SHMS detector hut for the design of the SHMS detectors. The beam sizes are taken into account in the construction of the latter. 

• SHMS Collimator 
  The slit system will consist of a permanent, remotely controlled collimator/sieve slit box in front of Q1, and a special calibration sieve slit that can be temporarily inserted by hand before the horizontal bender. 

• SHMS Horizontal Bender 
  Information about the prototype test performed in 2006 and the results of the simulation. The test results show that radiative heating is less than 1W, and so with in the design tolerance. 

• SHMS Shielding Design 
  Report on the contribution of backgrounds at 12 GeV in Hall C and the SHMS shield house design. The shield house will consist of separate detector and electronics huts, which will be made from concrete, lead, and boron in order to protect the experimental equipment from different types of background radiation.
