abstract = {As part of biological research carried out on plant
phenotyping within the Jülich Plant Phenotyping Centre, a
modality to detect the positron emitting radionuclides has
been setup. The investigation of transport of short-lived
carbon isotope $^{11}$C within plants using $^{11}$CO$_{2}$
as radiotracer fixed during the photosynthesis dark
reactions is the idea behind this research. The Flow and
distribution of $^{11}$C-labelled photo assimilates within a
plant can then be imaged using the PET (Positron Emission
Tomography) technology. To this end, a PET imaging system
has been developed. This consists of scintillation detectors
with scintillation crystals coupled to photodetectors. The
radiation, which is emitted after the uptake of the
radiotracer, causes ligh tpulses within the scintillation
crystals. This light is then converted into electrical
signals by the photodetector. The “phenoPET” system is a
PET scanner dedicated for plant research that employs
digital SiPMs (Silicon Photo Multipliers) as photodetectors
organised in 36 detector modules resulting in hit events
based on the triggered photon counts fitted in data frames
by acentral FPGA based unit. Present study starts with
developing a prototype that uses Ethernet FMC module (from
Opsero Electronic Design) with four Gigabit Ethernet ports.
Concerning illustration based on the pre framework design of
data transfer from detector modules, data stream flows from
each detector module (consisting of 4 tiles) to the FPGA
board (Xilinx Kintex-7 FPGA Mini Module Plus (Avnet)) on
LVDS lines. From the FPGA board to the readout computer, USB
3.0 (at 300 MB/s (2.4 Gbps)) is used. For the connection
from the readout computer to the storage system (located at
air-conditioned place), 10 Gigabit Ethernet is used.
Besides, our design is an addon to the module FPGA, data
stream from module FPGA is sent to ZC706 evaluation board
(Xilinx Zynq-7000 All Programmable SoC) when the Ethernet
FMC module is mounted on FMC (FPGA Mezzanine Card) connector
of the ZC706 board. The data is received by four ports over
the UDP server application running on the Zynq Processing
System. Data reduction technique like clustering on
timestamps (when multiple data packets occur in an event of
hits) is performed in a time window between 1 - 5 ns.
Processed data is sent out from one of the 10 Gigabit
Ethernet ports on ZC706 after frame skipping technique being
performed on every fifth frame. This study provides a
measurement of Ethernet bandwidth utilization versus actual
bandwidth from the stress tests performed on the datagrams.
It provides information about the utilization of multi
processors when the UDP application is running.},
