B inclusive digi and sim files at high Luminosities (C.Jones)

Samples of high luminosity data sets are available, from the private Cambridge production I ran for the LHCb Upgrade meeting.

Samples at fixed luminosities of :-

  • L= 5x10^32
  • L= 8x10^32
  • L= 1x10^33
  • L= 2x10^33

are available. At each luminosty, 500 B inclusive SIM (Gauss v25r7) and DIGI (Boole v12r10) files are available (more are available and can be copied to castor if needed). The digi files where produced with spillover turned ON, so in addition 1500 min bias SIM events are also available.

The files are available in castor at

  > nsls /castor/cern.ch/user/j/jonrob/data/HighLumi/

I hope the files names are self explanatory... The SIM files containing 10000000 are the B inclusive signal files, whilst those containing 10000000-30000000 are the corresponding min bias spillover files.

Note : Due to a ROOT feature, the minimum bias file at L=2x10^33 was truncated at 1.9G, due to a legacy 2G file limit and a second file (the XXX_1.sim file) was started. This means the DIGI files at this setting have less than 500 events.

In addition, a POOL XML catalogue file is available, which can be used to provide transparent DIGI->SIM access, if needed.

Finally, DSTs could also be made available, if there is interest. However, these DSTs where produced with an untuned Brunel application (v30r14) with almost no changes from the vanilla version (A few tweeks to the seeding and RICH). So the quality of these data sets is unknown. First indications from the Upgrade Meeting are not horrible though...
