Calibration of the Prompt L0 Trigger of the Silicon Pixel Detector for the ALICE Experiment

The ALICE Silicon Pixel Detector (SPD) is the innermost detector of the ALICE experiment at LHC. It includes 1200 front-end chips, with a total of ~107 pixel channels. The pixel size is 50 x 425 μm2. Each front-end chip transmits a Fast-OR signal upon registration of at least one hit in its pixel ma...

description The ALICE Silicon Pixel Detector (SPD) is the innermost detector of the ALICE experiment at LHC. It includes 1200 front-end chips, with a total of ~107 pixel channels. The pixel size is 50 x 425 μm2. Each front-end chip transmits a Fast-OR signal upon registration of at least one hit in its pixel matrix. The signals are extracted every 100 ns and processed by the Pixel Trigger (PIT) system, to generate trigger primitives. Results are then sent within a latency of 800 ns to the Central Trigger Processor (CTP) to be included in the first Level 0 trigger decision. This paper describes the commissioning of the PIT, the tuning procedure of the front-end chips Fast-OR circuit, and the results of operation with cosmic muons and in tests with LHC beam.
