001022075 520__ $$aThe 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.
