  5. 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 (doable in beam or laser tests) • all channels are read • no zero suppression, large amount of data (~800 byte/chip) • no read-out threshold, all signals seen • 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. 14th CBM Collaboration Meeting -- Walter F.J.

  7. First Beam Time Summary • Lots of data to be analyzed • more persons involved now in analyzing time-stamped data • many new analysis techniques are needed • Joint beam tests with several detector systems are a very valuable exercise • Proper shielding of setup is key to success of a self-triggered FEE system 14th CBM Collaboration Meeting -- Walter F.J.
