Abstract
| The upgrade of the ALICE Inner Tracking System uses a newly developed monolithic active pixel sensor (ALPIDE) which will populate seven tracking layers surrounding the interaction point. Chips communicate with the readout electronics using a 1.2 Gb/s data link and a 40 Mb/s bidirectional control link. Event data are transmitted to the readout electronics over microstrips on a Flexible Printed Circuit and a 6 m long twinaxial cable. This paper outlines the characterisation effort for assessing the Data Transmission Unit performance of single sensors and prototypes of the detector modules. It describes the different prototypes used, the test system and procedures, and results of laboratory and irradiation tests. |
