DAQ Test Beam Summary
The whole chain worked
1st successful proof of concept
Radek saw the very first spill in the online monitor !
we had only about 7 hours beam over 3 days, and took data
already on day one.
everything worked 'in principle'
Good basis to get all the details right
sure we had some 'surprises' and 'undocumented features'
can all be addressed now based on real experience

Towards the
real thing
17 October 2008
12th CBM Collaboration Meeting -- Walter F.J. Müller, GSI
22
Design of the CBM readout chain
'Starter Kits' and '1st round demonstrators' use existing
or pre-prototype read-out ASIC's, prime objective is fast
availability to support tests of concepts and building
blocks.
Key aspects for final CBM readout chain
scalability to full CBM detector size and data rates
provide interface to FLES (First Level Event Selector)
adapt to radiation environment
17 October 2008
determine where COTS components can be used
minimize functionality in exposed areas (on detector)
put complex logic into unexposed or shielded areas
