JUNO J ENERGETIC PARTICLE DETECTOR UNCALIBRATED V1.0

Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: October 23, 2025 | Last Modified: 2025-07-17
Abstract ======== This data set consists of the JUNO JEDI (Jupiter Energetic-Particle Detector) uncalibrated observations, also known as EDRs. The system is made up of 3 instrument subsystems (pucks) aligned in three directions on the spinning JUNO spacecraft. The pucks each have 6 look directions (telescopes) with a time of flight (TOF) and a deposited energy detection (SSD) system. In addition, the pulse height of the signal in the TOF system can be used for energy measurement. The instruments can be operated in a variety of modes, differing in the way they use and combine these measurements. More details are available in the INSTRUMENT.CAT file and the JEDI SIS. The EDRs are organized in files covering one day of spacecraft event time (SCET). There are potentially 10 different files per puck, corresponding to the available data gathering modes: HIERSESP, HIERSISP, HIERSTOFXER, HIERSTOFXPHR, LOERSESP, LOERSISP, LOERSTOFXER, LOERSTOFXPHR, NONPTOFXER, NONPTOFXPHR. Depending on how the pucks are operated, not all data types will be available for all pucks for any particular time range.
