0074
0075 Tracker:
0076 * T15: Phase2 tilted tracker (v6.1.6) w/ phase 2 pixel (v6.1.3) (Active geometry: same as T14. Material Budget: major update in IT, gathering info from recent Mechanical designs.)
0077 * T21: Phase2 tilted tracker. Outer Tracker (v8.0.0): TBPS update in Layer 1 (facilitate IT insertion) + In all TEDD, update sensors Z inter-spacing. Inner Tracker: (v6.1.5) from previous T17
0078 (TFPX: Changed sensors spacing within all double-disks + Increased distance between Disks 6 and 7 + TBPX portcards between Disks 6 and 7.)
0079 * T24: Phase2 tilted tracker. Tracker detector description itself is identical to T21 (OT800 IT615). Change of paradigm, entire description reworked to be compatible with DD4hep library.
0080 * T25: Phase2 tilted tracker. Outer Tracker (v8.0.0): same as T24/T21. Inner Tracker (v7.0.2): Based on (v6.1.5) (T24/T21), but with 3D sensors in TBPX L1. Compatible with DD4hep library.
0081 * T26: Phase2 tilted tracker. Outer Tracker (v8.0.0): same as T24/T21. Inner Tracker (v7.0.3): Based on (v6.1.5) (T24/T21), but with 3D sensors in TBPX L1 and 50x50 pixel aspect ratio in TFPX and TEPX. Compatible with DD4hep library.
