SCT Trigger/Logic Card SCT is developing a new trigger/logic card which might be of interest to other subsystems What is it? What will it do? What to do if you want one (or two or…) ? 13/04/2010 Dave Robinson ATLAS Run Meeting

Dave Robinson ATLAS Run Meeting What is it? Digital Atlas VmeElectronics (DAVE) card 6U VME Hardware writeable by VME and USB Can also be used on the bench with a power supply Design/Production/firmware by UCL and Cambridge Matt Warren, Martin Postranecky(TIM engineers) Maurice Goodrick(BOC) 13/04/2010 Dave Robinson ATLAS Run Meeting

Dave Robinson ATLAS Run Meeting What will it do? “NIM crate” in a vme card Generic NIM-like logic operations on NIM/TTL signals Mini CTP Programmable random gate generator Trigger rates up to 100kHz Simple and complex dead-times Minimum X clocks between triggers Minimum X triggers in Y clocks Readout of trigger history on interrupt 5-10seconds history at 100kHz rate 13/04/2010 Dave Robinson ATLAS Run Meeting

What to do if you want one? Contact me by 19th April Requests for small iterations in functionality might be possible, but functionality frozen by week starting 19th April Delivery expected late summer 2010 A small financial contribution might be expected from non-ID subsystems Existing orders: SCT (3) Pixels (2) TRT (2) Thilo (2) 13/04/2010 Dave Robinson ATLAS Run Meeting
