nXYTER: self-trigger vs. nXYTER: self-trigger vs. external-triggerexternal-trigger self-trigger Mode:

normal operation modenormal operation mode only channels with an amplitude above read-out threshold

are visible

external-trigger Mode: very tight timing requirementsvery tight timing requirements (doable in beam or laser

tests) all channels are readall channels are read no zero suppression, large amount of datano zero suppression, large amount of data (~800 byte/chip) no read-out threshold, all signals seenno read-out threshold, all signals seen useful for detector characterizationuseful 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.

First Beam Time SummaryFirst 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 exercisevery valuable exercise

Proper shielding of setup is key to success of a self-triggered FEE system

SummarySummary 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.
