Verification of the Simulation

Our verification effort is being led by Lei Wang (UMD), using code that was developed by Armand Zylberstejn (Saclay). For a description of the code used for the verification, click here.

Plots used for the certification of D0gstar are located here.

Plots for the certification of D0Sim are located here.

Plots to check that the reconstruction is still working for the MC are located here.

Descriptions of the changes by version:

Version
Changes
 Known Problems
  d0gstar/simpp d0sim  
head (test)      
t05.06.00 - Geometry changes: Solenoid, CC cryostat, some corrections in different TZ files which caused errors in the log file (mainly doubly defined volumes), some material definitions are corrected, modified SMT, layer 0 - New switch for geometry selection (Run1, Run2a, Run2b) - layer zero added - Bug removed for particles decaying at rest (caused long computing time of some events) - re-written GUSTEP - Bremsstrahlungs photons are stored in MC-Kine chunk (above 0.1 GeV) - Some other minor bugs and glitches removed the code is there, but the tz files are not yet. so, can not actually use for layer zero simulation yet
t05.05.00   smtdigi including Run II b layer zero rcp problem fixed calorimeter d0sim is sick
t05.03.00   smtdigi including Run II b layer zero new smtdigi had a bad rcp file. noise in smt effectively turned off; calorimeter d0sim is sick
t04.06.00 abandon all changes described in p15 branch. synch to p14.08.00 abandoned all changes described in p15 branch. synch to p14.08.00  
p17.03.XX moved outer radius of CFT a bit   still undertest; calorimeter d0sim is sick :

p17.02.XX     DO NOT USE :

d0gstar geometry in cft incompatible with that in d0sim
p17.01.XX    

DO NOT USE:

compiler problem causes it to hang when hadrons are run
p17.00.01 synched to p14.08.00; synched to p14.08.00;

DO NOT USE:

compiler problem causes it to hang when hadrons are run
p17.00.00    

DO NOT USE:
p16    

DO NOT USE:
Abandon P15 Branch. Do not use it! Pick up changes listed below for p15 branch in header (test) Branch (Nov 2003)
p15.07.00( when rebuilt after 5 nov 03) put in fix for cal unpack bug (fix went into p13/p14 at p13.08.00, but they forgot to put into p15, test until now  

DO NOT USE:

cal and SFT may still be sick
p15.06 no changes new CFT geometry file in geometry_db (not! in geant)

DO NOT USE:

calorimeter sick! SFT sick?
p15.05 no changes no changes

DO NOT USE:

calorimeter sick! SFT sick?

p15.04

1)add change to gufld needed to match change in mag_field

2) fix from Daniela for wmpd.tz (WAMUS scint hits in top octant were accidentally disallowed)

1) allow SAM access

2) update copy_to_rundata.sh so that it copies cal_nlc_146225.coef

DO NOT USE:

calorimeter sick! SFT sick?
p15.03

Major changes in magnetic field (click here)

Major updates in simpp (S)

allow SAM access

 

 sftdigi added new code to handle fibers outside of GEANT volume. DO NOT USE: crashes and problem in WAMUS scintillator.
switch compilers from kcc to gcc
p14.09.00 outermost radius of CFT moved a bit   note that we are still working on changing the geometry used by the track reconstruction to reflect the changes that went into d0gstar. We will not freeze this release until this is done. However, this has a neglible effect on the output.
p14.08.00 non-trivial change to D0gstar geometry. The geometry of the beam pipe was altered by Sahal Yacoob. Some copper cables were added to the SMT by Sudeshna Banerjee see D0 note 4498, 4799, and 4511 Some small scintillator counters were added to the bottom of the muon system and the chamber alignment was made more realistic, see d0note 4088.
  • Some code in spacegeom, geometry_system, and cft_geometry was updated to allow faster digitization of CFT hits.
  • Update the charge sharing and cross talk in SMT according to D0 note 4468
  • change geometry_db to rotate CFT so number scheme is same in MC and data. this is necessary for d0raw2sim overlay and subsequent analysis.
DO NOT USE. Geometry in d0gstar not compatible with d0sim
p14.07.00 no changes   none
p14.06 no changes add special link option to pileup so reads pileup events in order from pileup file. have to recompile to get this option. exe did not compile because the strange way simpp handles libraries lost the eventflags library
p14.04 no changes    
p14.03   1) sft digi routine were changed. something about the position of some fibers being wrong, and about returning fiber position instead of average doublet position.  
p13.08.00   1) calorimeter unpacking bug fixed.  
p13.06.01     DO NOT USE: calorimeter packing/unpacking bug

p13.05.00

     DO NOT USE: calorimeter packing/unpacking bug affects small energy deposits. Details on the bug can be found here.
