      abstract     = {The PET scanner phenoPET is a system dedicated for plant
                      research developed and used for phenotyping studies at the
                      Research Center in Jülich. The detector ring consists of 36
                      detector modules, which are equipped with LYSO scintillator
                      crystals coupled to digital SiPMs (DPC3200 by Philips
                      Digital Photo Counting). These photodetectors only provide
                      digital interfaces for configuration and read-out. No
                      electronics for analog processing are required. All detector
                      modules are connected to a central board based on a Xilinx
                      FPGA. On one hand, it collects and preprocesses the fast
                      output data providing the transfer to the data storage and
                      processing system via a USB-3 connection. On the other hand,
                      it enables the communication between the modules and the
                      controlling computer that sets up the detectors and controls
                      the measurements.The USB-3 transfer restricts the maximum
                      output rate to 380 MB/s, which requires controlled data
                      dropping within the FPGA in order to allow measurements with
                      activities that would exceed this limit. Presently we are
                      developing a new readout system that will eliminate this
                      bottleneck. We will replace the USB-3 by a fiber optics link
                      with a maximum data rate of 2GB/s. In addition, the new
                      central board will provide an embedded operation system
                      (PetaLinux) that has direct access to the hardware
                      interfaces for configuration and monitoring of the detector
                      modules. This will replace the controlling computer and our
                      control software can run directly on the board.},
