Operated reliable when taking data in test beams at DESY:2009: February – March, July, September2010: September, DecemberIn September 2010 the system operated with:7680 channels (60 Front End cards)3 RCUs, 2 DRORCsProblem: broken amplifiers on FEC, caused by discharges in GEM?Next testbeam: june 2011, with test of input protection on amplifiers

Development in Lund

DAQ-SALTRO16Same as for EUDET/LCTPCWhich has:no common DAQ interfaceno common TLU/DBOX trigger

Modifications needed forNew ”Front End Card”New backplanesMCM instead of FEC

Time scale: h/w & s/w september 2013

7

Control? implement a common server that can communicate with the DAQ process on one side, as the local server do, and with a common control on the other side.Event data transfer? Currently as local storage and sending raw binary data over network.

COMMON DAQ INTERFACE? COMBINED RUNNING?

LUND PART COMMON PART

Trigger systemDBOX – TLU trigger? to be fully implemented if any combined running(DBOX = local distribution of trigger/busy/reset/clock)Common DAQEUDAQ:?Some work was done to integrate DAQ process with EUDAQ, but lack of time/manpower and problem with ALICE C-code together with EUDAQ C++ code interrupted it.

Interface to common DAQ:Should not need to intregrate common daq code into the standalone daq core, to avoid code ”incompatibility”, e.g.:Control:CommonServer to convert common commands to local commandsData: address/port/format/handshake (library routine?) to send data over networkLocal DAQ:Should be possible to easily swap to local running and setup.

Development in Brussel/DESY

Implement DRORC in microTCA:Advanced Mezzanine Card (AMC)connect ed to RCU/MCM/FEC system

Development steps:Learn microTCAMake simple AMC as testNew DRORC

Two streams to/from DRORC:*Setup/Control *Data -> DAQ system: existing or new?

Common DAQ?Time scale of microTCA?
