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 position (i.e. 2) means OUT (the beam pass trough the TED);- Dump (i.e.3) means IN (the TED dumps the beam).
