The ALICE Silicon Drift Detector system

Beam test results of the irradiated Silicon Drift Detector for ALICE

The Silicon Drift Detectors will equip two of the six cylindrical layers of high precision position sensitive detectors in the ITS of the ALICE experiment at LHC. In this paper we report the beam test results of a SDD irradiated with 1 GeV electrons. The aim of this test was to verify the radiation tolerance of the device under an electron fluence equivalent to twice particle fluence expected d...

Detector Control System for the ALICE Time Projection Chamber

The Alice experiment is operated by a hierarchical structure of control layers. The various sub-detectors of the ALICE experiment are controlled by the Detector Control System (DCS). The topmost layer is the Experimental Control System (ECS) and controls the DCS, Data Acquisition (DAQ) and Trigger system (Figure 1). During normal operation the shift crew controls the detector at the ECS level. ...

The ALICE Pixel Detector Readout Chip Test System

The ALICE experiment will require some 1200 Readout Chips for the construction of the Silicon Pixel Detector [1] and it has been estimated that approximately 3000 units will require testing. This paper describes the system that was developed for this task.

Commissioning of the Silicon Drift Detectors of the ALICE experiment at the LHC

Silicon Drift Detectors (SDD) equip the two central layers of the Inner Tracking System of the ALICE experiment at the LHC. Main results of systematic studies of detector performance including noise, gain, drift speed and charge collection measurements will be reported. 1 ALICE experiment and SDD module Silicon Drift Detectors (SDD) [1] offer two-dimensional position reconstruction with a limit...
