Abstract
An integrated portable USB based readout interface for the ATLAS semiconductor trackers (SCT) has been built. The ATLAS SCT modules are large area silicon strip detectors designed for tracking of high-energy charged particles resulting in collisions on Large Hadron Collider (LHC) in CERN. These modules can be also used on small accelerators for medical or industry applications where a compact and configurable readout interface would be useful. A complete custom made PC-host software tool was written for Windows platform for control and DAQ with build-in online visualization. The new constructed interface provides integrated power, control and DAQ and configurable communication between the detector module and the controlling PC. The interface is based on the Field Programmable Gate Array (FPGA) and the high speed USB 2.0 standard. This design permits to operate the modules under high particle fluence while minimizing the dead time of the whole detection system. Utilization of the programmable device simplifies the operation and permits future expansion of the functionality without any hardware changes. The device includes the high voltage source for detector bias up to 500 V and it is equipped with number of devices for monitoring the operation and conditions of measurement (temperature, humidity, voltage). These features are particularly useful as the strip detector must be operated in a well controlled environment. The operation of the interface will be demonstrated on data measured with different particles from radiation sources.
