| DPMJET
Event Generator USERDUMP |
17/11/06 | The common
mgread routine could not dump the source particles.
Subscript
out of range on file line 117, procedure mgread.f/vxread. |
In mgread, the parameter MXPR has
to be increased: PARAMETER ( MXPR = 300 ) because dpmjet can generate more than 300 particles x event at 7+7 Tev |

DPMJET
Event Generator
|
7/11/06 | source particles multiplicity of p-p collisions at 7 Tev. Comparisons with different source of secondaries (DTUJET, DPMJET), we found some inconsistencies | We did not run the right event
generator dpmjet but the default one in the FLUKA
v3.1 which is not adapted to high energy physics. For calling DPMJET: $FLUPRO/flutil/ldpm3qmd -o executable name -m fluka source_routine name.o a source routine has to be developed for specificyng the parameters of the beams, and the SOURCE card is then also impacted. a output fortran file fort.19 is generated at the end of the FLUKA runs and tells that DPMJET was correctly run. |

The source was located on the
border between 2 regions: this can not be handled by
FLUKA. For a pointlike source description, the solution is to extent the region, so the source is located inside the region. For source positions distributed according to Gaussian distributions in x, y and z, a check has to be implemented inside the source routine to avoid any occurrence of a primary on a border between 2 regions. |
