Working geometry for 2014 run studies. Changes will be announced on the hps-software list; you should rerun SLIC on all your data after any change since old data may not work with up-to-date versions of readout sim/analysis/reconstruction.
- SVT rotated 30.52 mrad around target; single sensors for layers 1-3, double sensors with double readout (unganged) for layers 4-6
- ECal flange face at z=1318 mm and photon hole aligned at 30.52 mrad from target
- Front face of ECal crystals is z=1393 mm; ECal aligned so the 30.52 mrad photon beam intersects centerline of ECal at its front face
- All dead material defined using Geant4 primitives: SVT vacuum chamber, ECal flange and vacuum chamber (with honeycomb)
- Uniform magnetic field extending from z=-8.28 to 99.72 cm
- Vacuum (zero density) planes at z=15 cm, same shape as standard SVT layers; hits are saved for charged particles passing through these planes (for use in recoil electron studies)
- Vacuum (zero density) planes at magnetic field boundaries; hits are saved for all particles passing through these planes
- Vacuum (zero density) planes just downstream of the ECal flange; hits are saved for all particles passing through these planes

EngRun2015-Nominal-v3
Engineering run geometry with surveyed SVT and ECAL. Identical to HPS-EngRun2015-Nominal-v2, except:
- Top ECAL shifted up by 2.7 mm
- Bottom ECAL shifted down by 0.9 mm
HPS-EngRun2015-[SVTPosition]-v2
Engineering run geometry with surveyed SVT.
- Based on HPS-EngRun2015-v1
- Includes first pass of SVT survey.
HPS-EngRun2015-[SVTPosition]-v1
Engineering run geometry. Replaces the v0. The SVTPosition is either "Nominal" (+/- 1.5 mm to active sensor) or "Open" (+/~ 7mm to active sensor).
- Based on HPS-EngRun2015-v0
- Fixed bug in local sensor coordinate system.
HPS-EngRun2015-[SVTPosition]-v0
First version of engineering run geometry. The SVTPosition is either "Nominal" (+/- 1.5 mm to active sensor) or "Open" (+/~ 7mm to active sensor).
...
- Based on HPS-Proposal2014-v7
- Added the ECAL crystal support structure in front of the crystals.
- v9
- B-field is box dipole of By=-0.25T (applicable for 1.1 GeV)
HPS-ECalCommissioning-V3 (with and w/o fieldmap)
Official geometry for the Decembers 2014 ECal commissioning run
- As designed ECAL with asymmetric top/bottom gaps
- no SVT!
- B-field of -0.33T (in y)Added the ECAL cooling plates and pipes.
HPS-TestRun-v3
Official geometry for 2012 test run as-built.
...
- ALWAYS create a new detector when you make changes to the geometry
- make a subdirectory of hps-detectors/detectors; name of the subdirectory is the name of the detector
- add name of the detector to detectors/taglist.txt
- copy from another detector: compact.xml, detector.properties, SamplingFractions
- in compact.xml: change name and comment in <info> block
- in detector.properties: change name, change ConditionsReader if necessary (TestRunConditionsReader for 2012 test run, HpsConditionsReader for 2014 run) - both of these lines are required
- Create the LCDD file for use in slic: see below
Converting the compact.xml file to LCDD
...
Note that in these examples 3.4.0-SNAPSHOT will need to be appropriately modified.
The following will directly create the lcdd file:

java -cp distribution/target/hps-distribution-3.4.0-SNAPSHOT-bin.jar org.hps.detector.DetectorConverter -f lcdd -i compact.xml -o detectorName.lcdd

Note that it is easiest to run this command from the HPS detector-data directory, as the gdml directory, needed by most recent detectors, will be found automatically. You also need to specify the run number using -r <runNumber> to have the detector added to the conditions database |

The LCDD file can be viewed directly using SLIC:
