6. 9 October 2009 14th CBM Collaboration Meeting -- Walter F.J. Müller, GSI 6 nXYTER: self-trigger vs. external-trigger self-trigger Mode:  normal operation mode  only channels with an amplitude above read-out threshold are visible external-trigger Mode:  very tight timing requirements  very tight timing requirements (doable in beam or laser tests)  all channels are read  no zero suppression, large amount of data  no zero suppression, large amount of data (~800 byte/chip)  no read-out threshold, all signals seen  useful for detector characterization  useful for detector characterization (e.g. response functions) During September 2009 beam both modes were used  in general most of setup in self-trigger mode, and one selected detector in external-trigger mode.

38. 9 October 2009 14th CBM Collaboration Meeting -- Walter F.J. Müller, GSI 38 Summary Very successful beam test:  yes, we can  yes, we can build small systems with self-triggered FEE and operate the detectors Many lessons learned in the past 12 month  Firmware and Software in transition to V2.0 Hopefully soon also end of hardware shortage  Feb1nx Rev D designed, PCB in production  additional ROC manufactured in India Next step: turn all the experience into a straw-man design of the real CBM FEE/DAQ system.
