Hall C 12GeV Upgrade

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 Database lists 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.
