Description
For the upgrade of the ALICE Inner Tracking System a dedicated Monolithic Active Pixel Sensor – the ALPIDE - has been developed. It is 3 cm x 1.5 cm in size, features a spatial resolution of ~5um, an event-time resolution of <3us. The sensor can be thinned down to only 50um, making it suitable for high-resolution beam telescopes even at low beam energies.
Over the past months, we have been successfully operating a 7-plane telescope setup consisting of ALPIDE sensors at the CERN PS. A track resolution at the Device Under Test of 2-3um, depending on the exact mechanical configuration, was reached.
In this contribution, we will present the setup and its performance, give an overview of key measurements performed, and outline prospects for future developments.
