The JPL Open Repository (JOR) replaced the JPL Technical Report Server (TRS) in 2023. It is a repository for digital copies of technical publications authored by JPL employees. It includes journal articles (the Final Accepted Version), meeting papers, presentations, and other publications cleared for external distribution from 1992 to the present. It also include research datasets from 2022 on.

Years covered: 1992 to the present.
  • 1992-2021 records were originally on the JPL Technical Report Server (TRS) on Dspace system; those records were migrated to Dataverse in 2022.
  • Records with publication date 2022 or later are native to the Dataverse.
  • Data sets: 2022 to present
  • There are a few pre-1992 records. Those were added to the system on a case-by-case request basis.

  • Persistent IDs (PIDs):
  • 1992-2021 records have Handles
  • 2022 and later records have Digital Object Identifiers (DOIs).
    • Featured Dataverses

    Long-Wavelength PtSi Infrared Detectors Fabricated by Incorporating a P+ Doping Spike Grown by Molecular Beam Epitaxy
    Feb 2, 1993
    Lin, T.; Park, J.; George, T.; Jones, E. W.; Fathauer, R. W.; Maserjian, J., 1993, "Long-Wavelength PtSi Infrared Detectors Fabricated by Incorporating a P+ Doping Spike Grown by Molecular Beam Epitaxy", https://hdl.handle.net/2014/35030, Applied Physics Letters, JPL Open Repository
    By incorporating a 1-nm-thick p+ doping spike at the PtSi/Si interface, we have successfullydemonstrated extended cutoff wavelengths of PtSi Schottky infrared detectors in the long wavelengthinfrared (LWIR) regime for the first time. The extended cutoff wavelengths resulted from...
    Learning to Classify Map Data with Cascaded VLSI Neural Network Building Block Chips
    Feb 1, 1993
    Brown, T. X.; Duong, T.; Eberhardt, S. P.; Tran, M. D.; Daud, T.; Thakoor, A. P., 1993, "Learning to Classify Map Data with Cascaded VLSI Neural Network Building Block Chips", https://hdl.handle.net/2014/34856, USA, JPL Open Repository
    Paper maps are an important but unwieldy data format. To increase its utility, copious amounts of map data have been scanned into a digital map knowledge base. The next task in this knowledge base is to reduce this data to its underlying feature form suitable for analysis.
