Arrangement

How many Muon Stations per Sector?All fully assembled?All connected?

Main Sector

5 Neighbors

Due to Crate limitations no next wheel neighbor connection between sideways sectors

Readout

● Spy Readout– As it was during Testbeam– Full access to all data– Slow readout - to accelerate

● Implement 16bit accesses to JTAG● Decrease bit counter accesses● Accelerate JTAG frequency (???)● Check VME Controller Driver

– Flexible timing

We hope for a 1kHz readout

● Standard DAQ Readout– DAQ interfaces ready– Tests with FED-Kit soon– Access only to DAQ data– Requires a fully functioning TTC!– Timing given by the full system

● With this solution one faces all Trigger Synchronization problems of the final system!

Software

● S/W for Readout– Spy readout software exists

● minor overhaul necessary– DAQ readout should be written anyways for DCC test

● S/W for the Trigger Chain– Theoretically a Control S/W should exist for every Chain Member– Individual Control everywhere
