1. PANDA collaboration meeting FEE session
Communications
EMC meeting
EMC group assigned Myroslav Kravtsyuk as responsible for EMC readout electronics
Work Packages for development of EMC readout defined
Many packages got responsible institutes
Other detector groups should define work packages and assign responsible institutes
- can be discussed in Rauischholzhausen
MVD group triggered discussion about GBT usage in PANDA
Meeting with CERN Microelectronic group on March 4-th
FE/TDAQ workshop in Rauischholzhausen April 14-17
Registration for the workshop:
March 9-th 2010
PANDA collaboration meeting FEE session

2. PANDA collaboration meeting FEE session
Motivation
Some PANDA detectors and readout circuits will be exposed to high particle flux
MVD
Planar GEM
TPC (?)
EMC (?)
MVD group, lacking manpower, looks for a ready to use solution for high speed optical link
Possible solution:
GBT – Radiation hard high speed optical link

15. DAQ Architecture GBT SODA functions:
provision of absolute time- common clock
synchronization with beam structure
data flow control (throttling)
GBT
Detector Frontends
Data
Concentrator
First Stage
Super burst Builder
Second Stage
Super burst
Builder
Compute
Nodes
SODA
DAQ :
Beam structure : 2 us burst ns pause
Super burst : 500 us
Data block corresponds to one burst
Superblock corresponds to 500 us beam
DAQ builds super bursts by Round Robin
algorithm
200 GB/s sustained data rate

16. PANDA collaboration meeting FEE session
GBT and PANDA
GBT - interface between Data Concentrator and FEE
compatibility with SODA ?
GBT frequency 160MHz but it can run with MHz
…..
compatibility with FEE
GBT implementation requires significant hardware resources POWER, FPGA
Even having VHDL code porting to particular FPGA and maintenance of code to be considered
GBT to be used only for FEE where commercial components can not be used
-> two types of serial link protocols between FEE and Data Concentrator
-> GBT based Data Concentrator module

17. PANDA collaboration meeting FEE session
To do list
Verify compatibility with SODA - Igor
Verify compatibility with FEE - MVD group
Assign responsibility for Data Concentrator module development
Check if any other detector groups interested in RadHard optical links
Check for alternative radiation hard serial links
