One of the products of fusion reactions is neutrons, which, due to their lack of charge, provide a unique view into the parameters of the device. Lawrence Livermore National Laboratory (LLNL) in collaboration with the University of California, Berkeley (UCB) have designed, assembled, and fielded a robust and portable neutron detection system known as PANDA (Portable and Adaptable Neutron Diagnostics for ARPA-E) . This detector suite consists of three LaBr activation detectors that are calibrated to give a total neutron yield on shot, and twenty-four scintillators coupled to photomultiplier tubes (SPMT) . The SPMTs can be configured to attain spatial, temporal and/or energy information from fusion neutrons. The system was designed to be portable and is compartmentalized so that individual components can be used at different fusion facilities. During the duration of this work, part of the system was installed at the FuZE facility, a part of Zap Energy. Another component was installed that the CESZAR facility at the University of California, San Diego (UCSD) to support experiments by Magneto-Inertial Fusion Technologies, Inc. (MIFTI) . The diagnostics were successful at both locations and the LLNL/UCB team supported the data analysis by creating and ","cbCailwuuX2yN0dl","https://ap.wps.com/l/cbCailwuuX2yN0dl","pdf",324760,"English","# Table of Figures/Tables\n# Public Executive Summary\n# Acknowledgements\n# Accomplishments and Objectives\n# Project Activities\n# Project Outputs\n# Follow-On Funding","[{\"question\":\"What is the purpose of the PANDA neutron detection system in this report?\",\"answer\":\"PANDA is designed to measure fusion-produced neutrons in a portable way, providing calibrated total neutron yield and enabling spatial, temporal, and/or energy information from fusion neutrons.\"},{\"question\":\"How are neutron signals detected and calibrated in the system?\",\"answer\":\"The system uses three LaBr activation detectors calibrated to provide total neutron yield per shot, together with twenty-four scintillators coupled to photomultiplier tubes for configurable spatial, temporal, and energy information.\"},{\"question\":\"Where were the diagnostics deployed and what were the key outcomes?\",\"answer\":\"The diagnostics were installed at the FuZE facility and the CESZAR facility at UCSD.
