Charged Particle Tracking with the Timepix ASIC

Understand

A prototype particle tracking telescope has been constructed using Timepix and Medipix ASIC hybrid pixel assemblies as the six sensing planes.

• Each telescope plane consisted of one 1.4 cm2 assembly, providing a 256x256 array of 55 micron square pixels.
• The telescope achieved a pointing resolution of 2.3 micron at the position of the device under test.
• During a beam test in 2009 the telescope was used to evaluate in detail the performance of two Timepix hybrid pixel assemblies; a standard planar 300 micron thick sensor, and 285 micron thick double sided 3D sensor.
