Abstract
The ProtoDUNE-SP is a single-phase liquid argon time projection chamber (LArTPC) prototype for the Deep Underground Neutrino Experiment (DUNE). Signals from 15,360 electronic channels are received by 60 Reconfigurable Cluster Elements (RCEs), which are processing elements designed at SLAC for a wide range of applications and are based upon the “system-onchip” Xilinx Zynq family of FPGAs. The RCEs are housed in industry-standard ATCA shelves on a custom blade, called the Cluster on Board (COB). The RCE platform and its processing functions for the ProtoDUNE-SP will be presented.
Highlights
The Deep Underground Neutrino Experiment (DUNE) [1] is a leading-edge, international experiment for neutrino science and proton decay studies
ProtoDUNE-SP [2], the second of two prototypes illustrated in Fig. 1, is a single-phase liquid argon time projection chamber (LArTPC) with 0.77 kton liquid argon in a 10 × 10 × 10 m3 cryostat
The baseline data acquisition system (DAQ) system is based on the Reconfigurable Computing Elements (RCEs) [3] to read out 5 of 6 Anode Plane Assemblies (APAs), while an alternative system, Front-End LInk eXchange (FELIX) [4], is used for the remaining APA
Summary
The Deep Underground Neutrino Experiment (DUNE) [1] is a leading-edge, international experiment for neutrino science and proton decay studies. The far detector will comprise four >10 kton liquid argon time-projection chambers (LArTPCs) sub-detectors placed 1.5 km underground. ProtoDUNE-SP [2], the second of two prototypes illustrated, is a single-phase LArTPC with 0.77 kton liquid argon in a 10 × 10 × 10 m3 cryostat. It comprises two anode planes, which are separated by a central cathode plane into two drift volumes. Digitized wire signals of 12-bit ADCs at 2 MHz are read out via Warm Interface Boards (WIBs) installed on the top of the cryostat. The baseline DAQ system is based on the Reconfigurable Computing Elements (RCEs) [3] to read out 5 of 6 APAs, while an alternative system, Front-End LInk eXchange (FELIX) [4], is used for the remaining APA
