CLICdp: Event Display

Detector Sketches

Summary

Implemented DrawDetectorDD4hep.cc /.h + extended/corrected drivers Difficulties:

– Understand code + its structure – Interpretation of given geometry parameters – Generalization ←→ no hard coding

Result:

– No GEAR needed for drawing – Code is detector-independent (CLIC & ILD) – Compact and documented code

CLIC_o2_v01.xml

SIM1_CLIC_o2_v01_500GeV.slcio

ILD_o1_v05.xml

Detailled Geometry

ILD's VXD drawn as a set of CEDTubes (l.) or CEDGeoBoxes (r.)

Constraint:

– detElement == tracker && has ZplanarData::Layer

6

VisAttributes & Color Conversion

7

Parameter Interpretations

• 1. ZdiskPetalsData::layer →

CEDGeoTube

Example: CLIC Tracker Endcaps

→

• 2. Interpretation of phi0:

ILD's SIT

8

Other „Touched“ Drivers

(all labeled in src code)

SEcal04_Barrel.cpp:

• added phi0 and outersymmetry to returned extension
• consistency changes in calculated LayerCalorimeterData parameters

Scoil02_geo.cpp & Solenoid_o1_v01_geo.cpp:

• solenoid described as set of LayeredCalorimeterData::Layer 's
• cellsize0 := <z> = 0, cellsize1 := dz/2

ZplanarTracker_geo.cpp:

• added/set visAttribute to volume (<=> visAttr. of CLIC's vertex barrel)

TrackerBarrel_o1_v01_geo.cpp

• zHalfSensitive = right most position of sensor + its half width

(consistency with existing drawing)

VXD04_geo.cpp:

• offsetSensitive → 0.5 offsetSensitive (better fit of tracks)

Bugs (?):

1) Comments in xml-steering files ignored 2) CEDGeoTube artefacts for phi0 < 0, deltaPhi < 0 is fine 3) Cuts in CEDViewer do not always work as expected (still investigating)

10

ToDo's:

1) Find/Implement visAttributes for SET/SIT (ILD) 2) Commit + Push (How?) 3) Proceed
