Results of a Real-Time Data Acquisition System under WindowsXP for the TRIC Experiment * — •Deepak Samuel — Helmholtz Institut für Strahlen- und Kernphysik
For the Time Reversal Invariance Experiment at COSY (TRIC) in Jülich the polarization correlation Ay,xz is to be measured to an accuracy of 10−7. This requires the development of a robust, fast, reliable, and flexible real-time operating system. WindowsXP was chosen because of its proven productivity with Venturcom’s Real-Time Kernel for fast interrupt handling. Interrupts are identified and executed within about 6 µ s and a CAMAC module is read or written to within 1 µ s. The implementation of the real-time kernel, the interrupt handling, the synchronization with WindowsXP and the organization of the data acquisition under Windows as well as the interplay with the No-dqlive No-dqdisplay of the data with ORIGIN graphing software will be discussed. *Work supported by the FZ Jülich and the BMBF
