GTK
The Gigatracker (GTK) is designed to track the incoming beam particles. Further information can be found below:
Aim: measure time, direction, and momentum of all the beam tracks (~ 109/sec)
Three stations in vacuum of Si-pixel (300x300) mm, 200 mm thick, p-in-n
Station schematic
- 18000 pixel/station- dimensions: (60x27) mm2
- 10 ASIC chips bump-bonded to the sensor
Performances:
- Time resolution: 200 ps/station (rms)
- Angle resolution: 14 mrad (rms)
- Momentum resolution: 0.2%
