Experimental Hall C
----------------------
  • SIMC is a fortran based program simulating acceptance functions from the SOS and HMS in Hall C. It is currently set up to simulate the following processes : 


    • 1. Elastic/Quasielastic (e,e'p) from Hydrogen, Deuterium, Carbon, Iron, and Gold. All other targets are easily added if you provide a spectral function. 

    2. (e,e'$\pi$) from Hydrogen, Deuterium, and Helium-3. Other nuclei can be added relatively easily, with a user provided momentum distribution.

    3. (e,e'K) from Hydrogen, Deuterium, and Helium-3. You can also generate bound hypernuclear final states. Other nuclei can be added relatively easily, in basically the same way as for pion production.

    4. The phase space option can be implemented fairly easily.

    SIMC takes in account energy loss, radiative corrections, multiple scattering and particle decay. The detailed model of the magnets include target/HRS offsets, model of the magnetic elements, apertures at front, back and middle of the magnet as well as beam pipes and collimators and cuts based on detector active areas where appropriate. 
     

  • The standard version of SIMC include an implementation of the HRS from Hall A via the selection of the electron_arm and hadron_arm. Choose 1/2/3/4 for HMS/SOS/HRS-R/HRS-L.

  • A preliminary version of SIMC including a model of the SHMS is under development. Contact  Mark Jones  for more informations.
  • Preliminary version of SIMC including a model of MAD spectrometer is under development. Contact  Zein-Eddine Meziani for more informations.
  • SIMC as it is  can be run on  ALPHA,  SUN  and  HP. A few tweaks to the MakeFile may be necessary if the libraries have changed around. It can be made to operate with Linux using the ABSOFT compiler, this may require a few tweak to the code. John is working on putting the information on those change together
