mars area for Emittance exchange calculations.
Dear Raja,

Welcome to the MARS club! You can run the code on any of the UNIX or LINUX
Fermilab AFS machines or on a Beams Division cartoon cluster.
To get started, go to /afs/fnal/files/home/room1/mokhov/restricted/mars14
on AFS or to /home/mokhov/restricted/mars14 directory on cartoon and copy to
your area GNUmakefile, MARS.INP, m1402.f, marsmain.f, GEOM.INP, and
MARS.INP.exgeom files. To reproduce a sample problem of that in my directory
just say

make  (or gmake on UNIX AFS)
time ./rmars-bnab-fems-linux &   (last suffix is a OS system you are on).

In several seconds you will get MARS.OUT and MTUPLE, files which must
coincide with mine. You can also try an "extended geometry" option
replacing MARS.INP with MARS.INP.exgeom, a MTUPLE.EXG file is generated
then additionaly, ALTHOUGH THIS OPTION IS NOT RECOMMENDED FOR NEXT TWO MONTH
BECAUSE IT IS UNDER COMPLETE RE-BUILDING! One can generate numerous
histograms, stored in mars.hbook, for surface and volume detectors, as
described in MARS memos and comments. You can change CTRL 0  in MARS.INP to
CTRL 1  to activate  MARS GUI for geometry, track visualization and for
displaying histograms from mars.hbook. One can generate a TRACK.PLOT file by
placing TAPE 18 into the input sequence and running it for about 5 events.
Everything is quite self-explainatory. Be aware that MARS.OUT, mars.hbook
and all MTUPLE files are re-written at each run, therefore you should rename
those with the good statistics to something like MARS.OUT.1 and mars-1.hbook
if you need them.

Then, in a separate directory, you can create your MARS.INP and m1402.f
for your particular problem. As a guide, use the MARS manual from
the web page and MARS memos. The manual is not-up-to-date, a new one will
be ready soon. Visit "Secure MARS page" at http://www-ap.fnal.gov/MARS/ for
memos and a strongly recommended MCNP option for precise low-energy neutron
physics (available currently on cartoon and fnpc51). 

AN UPDATED MARS DECK TO CALCULATE PARTICLE YIELDS IN THE FEASIBILITY-2
CONFIGURATION IS ATTACHED TO THIS MESSAGE.

                     Good luck!
