idea16/04/[email protected] 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

reduce cost/channel for large systems2.) certified crate standard

SRS MinicrateConclusions16/04/[email protected] : a
(first?) complete & open solution for the readout of MPGD
detectorsChiplink concept proven: so far 3 types of SRS frontend
hybrids Portable Minicrates for the Desktop and LaboratorySRS
developers contribute on all fronts to make the system
completeEurocrates for scalable systems up to very large size
Rack-based systemsSRU 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 Labs2012 SRS demand ( Million Eu ) exceeds by large the
first 2012 production First semi-commercial production of SRS in
2012 expected with impatienceCERN-store adopted sales and logistics
of SRS as isFully commercial SRS pardigm under
negotiationCommercial ATCA crate standard very promising for new
look and feel of SRSNovel ideas for SRS cards with MPGD-specific
