7-ch Si-Drift Detector Data-Acquisition System
Project Goal:Development and realization of a data-acquisition system (DAQ) for 7-ch Si-drift detector modules (SDD).Project Status:Finished in 2009 |
|
The PXI-based DAQ system is collecting and measuring electrical signals from the SDD and transducers and putting them to a computer for histograming and to safety circuits for user-friendly and safe usage, respectively. The system provides all necessary supply voltages and takes over device control. The master is formed by a versatile single-board computer for PXI-bus control with processor, on-board memory, hard disk, and PCIe Gigabit Ethernet controller for high-speed communication. An A/D converter board offers a 12-bit resolution and is operated at 1 MSps per SDD channel. An user-specific gate signal can be used for beamline-controlled data taking. The SDD module's ambient temperature, humidity and pressure are also monitored. |
