Dear members of the physics working groups,


Happy New Year to all!


As we are moving forward with (more) realistic physics simulations and 
detector responses, please find below  information regarding the disc 
space available for your simulation efforts.

With questions, please contact any of the staff listed at the bottom of 
the attached email.


Best regards,

Volker

Dear all,

1) We have a disk space on ifarm, which we are using currently as a 
storage for different MC samples
     /work/eic/mc
(you should have a jlab account and be a part of the "eic" group)

    you could find there some samples for different sub-processes:
     a ) examples for minbias DIS or PHP ( LUND format)
           /work/eic/mc/PYTHIA_6.5/

      b)  also  examples in HEPMC format
              /work/eic/mc/HERWIG_6
              /work/eic/mc/PYTHIA_8/
     c)  BEAGLE, etc ..

Please, use this space, for your MC files ( please, do not forget to 
include also log file with beam parameters, cuts and cross section 
information).  At some point we want to move those files into a 
web-database interface such as a HEPSIM.

It would be also nice  to keep next to it a running version of the 
corresponding event generator ( with instructions how to run and/or 
control cards).

Please, also indicate  and/or provide a reader in case the output file 
format  is different from the currently supported (LUND,HEPMC, BEAGLE)


2) Just as a reminder,   we (JLEIC)  are colliding in horizontal ( X-Z) 
plane ( crossing angle a=50mrad )
protons :  (-sin(a), 0, cos(a) )
electrons: (0,0,-1)


3)   We would  like to suggest  to  use those beam energies  3, 5,  10, 
12 GeV for Electron beam
       and 200, 100, 40  for  the Proton/Ion beam.

CM energy   E e (GeV)    E p (GeV)       Lumi ( x10^33)
  21.9                  3                    40        2.3
  44.7                  5                   100   10.6
  63.3                   5                  200      9.3
  89.4                  10                 200     1.6
  98                      12                 200     0.71



Please,  send this info to the  other members of your group.
and let us  know if you have any questions!

Kind regards, Yulia, Markus, Dmitry
