      abstract     = {In the frame of the German Plant Phenotyping Project (DPPN)
                      we developed a novel PET scanner. In contrary to a clinical
                      or preclinical PET scanner the detector rings of the Plant
                      System are oriented in a horizontal plane. The final system
                      will be equipped with three rings covering a Field of View
                      (FOV) of 18 cm diameter and 20 cm axial height. One detector
                      ring is formed by 12 modules. Each module contains four 8×8
                      pixel digital SiPM devices DPC-3200-22-44 (Philips Digital
                      Photon Counting) connected to a PCB and four scintillator
                      matrices with 16×16 individual LYSO scintillators. Crystal
                      size is 1.85×1.85×10 mm3. The matrices are composed with
                      both reflective and transparent contact faces between the
                      crystals in order to optimize crystal identification. A
                      cooling system keeps the detectors below 5°C and limits the
                      dark count rate. Data are already preprocessed by the
                      Cyclone FPGA (Altera) in the module and transmitted from
                      there at 50MiB/s to the base board. The base board collects
                      the data from all modules and allows coincidence detection
                      performed on a Kintex-7 FPGA (Xilinx). Finally the data link
                      to the computer system for image reconstruction is realized
                      via an USB 3.0 connection. Due to the fast photodetectors
                      the system is dedicated to work with rather high activities.
                      Preliminary measurements showed a coincidence peak of 250 ps
                      FWHM between two detector elements and an energy resolution
                      ΔE/E = $12\%.$ This paper will present first results from a
                      one ring system with a FOV of 18 cm diameter and 6.5 cm
                      axial height.},
