Front End Electronics
Hardware is based on ALICE TPC readout electronics
Standalone DAQ with ALICE drivers/libraries
Operated reliable when taking data in test beams at DESY:
2009: February – March, July, September
2010: September, December
In September 2010 the system operated with:
7680 channels (60 Front End cards)
3 RCUs, 2 DRORCs
Problem: broken amplifiers on FEC, caused by discharges in GEM?
Next testbeam: june 2011, with test of input protection on amplifiers
Multi Chip Module
16 ch ALTRO
Same as for EUDET/LCTPC
no common DAQ interface
no common TLU/DBOX trigger
Modifications needed for
New ”Front End Card”
MCM instead of FEC
h/w & s/w september 2013
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.
DBOX – TLU trigger?to be fully implemented if any combined running
(DBOX = local distribution of trigger/busy/reset/clock)
EUDAQ:?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.:
CommonServer to convert common commands to local commands
address/port/format/handshake (library routine?) to send data over network
Should be possible to easily swap to local running and setup.
Implement DRORC in microTCA:
Advanced Mezzanine Card (AMC)
connect ed to RCU/MCM/FEC system
Make simple AMC as test
Two streams to/from DRORC:
*Data -> DAQ system: existing or new?
Time scale of microTCA?
