Ongoing tasks/projects, open issues

See:

Geometry and mis-alignment for simulation

Last update: 16th April 2009

It was agreed that, ultimately, the 2008 simulation should simulate a realistic detector based on the surveyed detector, not the ideal ("Optimisation TDR") detector simulated in DC06
See here for the various issues

Overlap checking can be done in Gauss for what Geant4 sees with special tool DAVID and DAWN. The list of the overlaps identified with Gauss v37r0(DDDBtag = "head-20090330") has been produced by Marco Pappagallo and can be found here.

Conditions for simulation

Last update: 16th April 2009

The simulation (and reconstruction of simulated data) will get a copy of the necessary online conditions from a SIMCOND database.

See here for the various issues

Marco Cl. has provided versions of SIMCOND containing the existing ONLINE data structure, and the conditions included in the latest LHCBCOND tags. Not all alignment conditions are included since they cannot be taken into account correctly by Gauss: in particular no alignment different from zero is set for ST and OT. There will also be a version corresponding to the nominal positions (not the survey) for which the VELO already exist. SIMCOND contains the magnet variables from online and has values for full field up and down and for magnet off. All directory in ONLINE will be copied to SIMCOND once they are available: we will then need to decide what values are set in the variable and the corresponding tags for productions.

The global tags in SIMCOND begin systematically with sim and the date YYYYNN (higher that that of the DDDB tag they are related to (ie. the corresponding geometry to which they apply)

Global tags have then a field used to identify specific values for following variables:

  • perfect or misaligned (including survey) geometry
  • setting for magnetic field
  • motor position for VELO

Beam conditions (including beam energy, bunch filling schema, crossing angle, beta*, beam size, luminosity) are instead set at initialization of Gauss as properties and stored in a DataObject in the /Gen tree. This corresponds to the conditions the simulation is run with. In fact Boole and Brunel should then be configured appropriately based on the SIMCOND tag chosen (eg. number of spillover events unless spillover is moved to Gauss, and field on/off). A dedicated configurable that will provide a translation from a given tag to the configurables of the applications will be available and the translation map distributed externally with the CondDB.

List of available global tags and corresponding variables settings:

Global tag with DDDB Velo alignment Velo motor position Magnetic field

Samples for validation

Last update: 23rd January 2009

A set of samples are necessary for validating a new production version, new versions of Geant4 and of generators. The production of these samples should become automated and the results published on a dedicated web page. This samples are produced by the production system, so that the all chain is exercised. It should also be investigated if the Data Quality/Monitoring infrastructure is suitable for this. Finally a new facility called QMTests is available within the Gaudi context, its suitability for this should also be investigated.

Two different macro-sets are produced depending on what need to be validated:

  • particle-gun, min bias and inclusive samples (sim+digi)
  • physics samples (dst files)

The list of sample to be produced, status of requests and productionIDs for them can be found here.

  • Work in progress, under construction When using _HP physics list G4 uses NDL cross section data and a long set of warning is issued as for many atoms only neutron cross sections of the natural composition exists and specific atom isotopes are instead used in the LHCb material list.
  • Work in progress, under construction Gauss stops when using a different PDF for Lamdba studies, reported by Raluca, WRONG LHAPDF set number = 20650 given! STOP EXE!, Patrick, Gloria, Raluca investigating. Could be that either chosen PDF is not distributed with Gauss if running remotely or available only in newer version of lhapdf.

  • Warning, important Crashes with Hijing from MagneticField integrator (G4exception not caught) when extending geometry upstream reported by Plamen, bug #48701, probably the same as #50862 (need to check few log files in production, just many more particles going into that direction).
  • Work in progress, under construction Crashes when using QGSP_BERT_HP for low energy muon background, reported by Alessia. Gloria looked into it and could not reproduce it with Gauss v37r2. Alessia has been informed with instructions on how to run it.

  • Work in progress, under construction Gauss stops when using a different PDF for Lamdba studies, reported by Raluca, WRONG LHAPDF set number =       20650 given! STOP EXE!, Patrick, Gloria, Raluca investigating. Could be that either chosen PDF is not distributed with Gauss if running remotely or available only in newer version of lhapdf.

When using HP NDL data is used and a long set of warning is issued as for many atoms only neutron cross sections of the natural composition exists and specific atom isotopes are instead used in the LHCb material list.

Marco Cl. has provided a first version of SIMCOND containing the existing ONLINE data structure, and the conditions included in the latest LHCBCOND tags. Not all alignment conditions are included since they cannot be taken into account correctly by Gauss: in particular no alignment different from zero is set for ST and OT. There will also be a version corresponding to the nominal positions (not the survey) for which the VELO already exist.

This corresponds to the conditions the simulation is run with. In fact Boole and Brunel should then be configured appropriately based on the SIMCOND tag chosen (eg. number of spillover events or field on/off). A dedicated configurable that will provide a translation from a given tag to the configurables of the applications will be available and the translation map distributed externally with the CondDB.

Beam conditions (including beam energy, bunch filling schema, crossing angle, beta*, beam size, luminosity) are instead set at initialization of Gauss as properties and stored in a DataObject in the /Gen tree.

In fact Boole and Brunel should then be configured appropriately based on the SIMCOND tag chosen (eg. number of spillover events unless spillover is moved to Gauss, and field on/off). A dedicated configurable that will provide a translation from a given tag to the configurables of the applications will be available and the translation map distributed externally with the CondDB.

Marco Cl. has provided a first version of SIMCOND containing the existing ONLINE data structure, and the conditions included in the latest LHCBCOND tags. Not all alignment conditions are included since they cannot be taken into account correctly by Gauss: in particular no alignment different from zero is set for ST and OT. There will also be a version corresponding to the nominal positions (not the survey) for which the VELO already exist. SIMCOND contains the magnet variables from online and has values for full field up and down and for magnet off. All directory in ONLINE will be copied to SIMCOND once they are available: we will then need to decide what values are set in the variable and the corresponding tags for productions.

The global tags in SIMCOND begin systematically with sim and the DDDB YYYYNN tag they relate to (ie. the corresponding geometry to which they apply)

Global tags have then a field used to identify specific values for following variables:

  • perfect or misaligned (including survey) geometry
  • setting for magnetic field
  • motor position for VELO
  • beam conditions (including beam energy, bunch filling schema, crossing angle, beta*, beam size, luminosity
This corresponds to the conditions the simulation is run with. In fact Boole and Brunel should then be configured appropriately based on the SIMCOND tag chosen (eg. number of spillover events or field on/off). A dedicated configurable that will provide a translation from a given tag to the configurables of the applications will be available and the translation map distributed externally with the CondDB.

Samples for validation

Last update: 7th July 2008

A set of samples are necessary for validating a new production version and new versions of Geant4. The production of these samples should become automated and the results published on a dedicated web page. It should be investigated with Stuart if this should make use of the production system or a dedicated set of Ganga scripts. It should also be investigated if the Data Quality/Monitoring infrastructure is suitable for this. Finally a new facility called QMTests is available within the Gaudi context, its suitability for this should also be investigated.

The list of sample to be produced is below:

  • LHEP parameterised modeling of hadronic interactions (G4)
  • QGSP modeling using Quark Gluon String model for high energy hadronic interactions of protons, neutrons, pions, and Kaons. The high energy interaction creates an exited nucleus, which is passed to the precompound model modeling the nuclear de-excitation. (G4)
  • EM option1 EM processes using parameters optimised for better CPU performance at the cost slightly less precise physics (G4)
  • EM standard EM processes with default setting using standard parameters tuned for best physics performance (G4)
  • DRay off production cuts as follow: e- 10 km, e+ 5 mm, gamma 10 mm (G4)
  • DRay on production cuts as follow: e- 5 mm, e+ 5 mm, gamma 5 mm (G4)
  • KineHT tracking cuts (kinetic E) as follow: hadrons/mu+/mu- 10 MeV, e+/e-/gamma 1 MeV, others none (Gauss)
  • KineLT tracking cuts (kinetic E) as follow: hadrons/mu+/mu- 1 MeV, e+/e-/gamma 0.1 MeV, others none (Gauss)

Simulation in LHCb

Introduction

Gauss is the LHCb Simulation software, built on the Gaudi Framework.
It consist of a first phase where the events are generated (e.g. pp collisions at 14 TeV) and a second phase where the particles are propagated trough the LHCb detectors.

Coordinators

The Gauss release manager is Gloria Corti. The list of topics and coordinators/contacts is here.

Gauss Web

The main Gauss web page containing release information and links to user guides and tutorials, is here.
