Data Acquisition
The data acquisition available at the Laboratory for Detector Science is modeled after the CEBAF (Continuous Electron Beam Accelerator Facility) Online Data Acquisition (CODA) system. The system involves a single board computer (Readout Controller) controlling a VME backplane which transfers digitized data from the VME backplane to a Host Computer. The Readout Controller (ROC) runs the VxWorks operating system and the host computer runs the CentOS ( free Red Hat) operating system. Libraries to control the VME modules are cross-compiled on the Host computer and then downloaded to the ROC. The suite of software packages which comprise CODA are used to manage the transfer of data from the ROC to the host computer.
