SRS idea

16/04/2012 Hans.Muller@Cern.ch

- choose the frontend ( ASIC, hybrid) that fits your detector- provide a common readout backend with standard DAQ SW- start from minimal systems - > scale to large systems if needed

SRS chip-link: HDMI cheap, v. high quality , 3Gbit/s, power, works very well

Project*: re-map SRS in ATCA

HDMI connectors

Equivalent of SRS ADC card

1.) higher channel integration => reduce cost/channel for large systems2.) certified crate standard 3.) replace DTC cables by backplane

Conclusions

16/04/2012

SRS : a (first?) complete & open solution for the readout of MPGD detectors Chiplink concept proven: so far 3 types of SRS frontend hybrids Portable Minicrates for the Desktop and Laboratory SRS developers contribute on all fronts to make the system complete Eurocrates for scalable systems up to very large size Rack-based systems SRU box for the readout of 40 FEC cards to one link (10 GBE) Up-scaling of small systems : keep the crate-based electronics, same SW Tens of 2011 SRS systems already deployed in various Labs 2012 SRS demand ( ¼ Million Eu ) exceeds by large the first 2012 production First semi-commercial production of SRS in 2012 expected with impatience CERN-store adopted sales and logistics of SRS “as is” Fully commercial SRS pardigm under negotiation Commercial ATCA crate standard very promising for “new look and feel ” of SRS Novel ideas for SRS cards with MPGD-specific functionality (trigger, HV, UV pulsing) Sponsors, Developers, manpower, more Ideas, Welcome
