• Status of Central Barrel– SPD– SDD– SSD– Thermal shields
• Status of RB24 & RB26 side– Support cones– Cables, cooling tubes, and ducts– Patch panels, cable trays, and Shoe boxes– ITSAMS system
• Material Definitions• Service code
– Step manager– Module decoding routines– Simplified geometry for fast display

• Sensitive volume must have thin direction in Direction• Z direction || to ALICE Global Z direction• Must follow ALICE naming and numbering conventions• Sensitive volume name ITS1, ITS2, ITS3, ITS4, ITS5, & ITS6.• Note, layer, Ladder, and Detector numbering schema not
allowed (does not follow ALICE standards).• Follow hardware conventions when ever possible
– Avoid inversion– Use measured positions when known
• Make Detectors repositionable independent of other non-sensitive objects
• Make volume/object names meaningful• Note, location of non-sensitive material known to about 1mm
absolute only.
