  • New TF3Chip class added to handle chip creation (inspired by the Alpide class). The chip is now 300 um thick. Final real ASIC dimensions are now used
  • Modules are now composed of 6x2 chips. Chips are separated by a 200 um gap. Modules along the stave are separated by a 200 um gap.
  • The iTOF and oTOF length is updated taking into account the new mechanical constraints
  • The stave service volume now carries all the remaining material budget (expected 2% X0 from services) -> in the next update this will be separated from the sensitive stave module
  • Overlaps were checked both with the deterministic and MC methods: no overlaps were detected with the default configurations.
  • Layer radius, length, and segmentation parameters (number of staves + tilt angle) are now configurable, enabling optimization studies on the detector layout
  • The default chip segmentation now includes the end of column passive region
