sPHENIX discussion of electronics

[Martin Purschke <purschke AT bnl.gov>]

Dear all,

I'd like to submit the following abstract for the real-time.

Please send me you suggestions you have to improve it.

Thanks,

        Martin

> named "sPHENIX", will be based on the former BaBar magnet and will
> include, in addition to the existing PHENIX Silicon Vertex Tracker in
> a modified configuration and additional tracking detectors, hadronic
> calorimeters and a new electromagnetic calorimeter.

> The calorimeters are read out with silicon photomultipliers and
> waveform digitizing electronics. The digitized waveforms are read out
> with custom PCIe boards that allow multiple streams with bandwidths of
> up to 5GBit/s. Focusing on the calorimeters, we will describe the
> goals and design of the sPHENIX experiment, the design of the
> digitizers, and the results we got with current prototypes. By the time
> of the conference, we will have data from a test beam at FermiLab that will
> test the readout under beam conditions.
> 
> We will also detail the design of the FPGA-based readout cards, and
> how we implement the so-called "multi-event buffering" in the
> front-end which has traditionally enabled PHENIX to take data at rates
> rivaling or exceeding the LHC experiments.
