Collimators positions display on DIP - TCDD - TCDIH - TCDIV - TCLA - TCLIB - TCP - TCSG - TCTH - TCTVA - TDI Distance in millimetre with respect to the beam orbit which coincides with the collimator centre; For the coordinates system please refer to the following slides. Collimators apertures : - for all collimators except TDI: min gap ~ 1mm; gap max ~ 60mm; - for TDI: min gap ~ 3mm; gap max ~ 120mm.

Collimators positions display on DIP - TCDQP Remark: The TCDQ has only 1 jaw Distance in millimetre with respect to the beam orbit which coincides with the collimator centre; For the coordinates system please refer to the following slides.

Beam aborbers positions display on DIP - TED UnknowPosition=0 Installation=1 Beam=2 Dump=3 Transport=4 UndefinedPosition=5 - Beam position (i.e. 2) means OUT (the beam pass trough the TED); - Dump (i.e.3) means IN (the TED dumps the beam).
