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

    In order to use this feature you must have at least one published dataverse.

    Publish Dataverse

    Are you sure you want to publish your dataverse? Once you do so it must remain published.

    Publish Dataverse

    This dataverse cannot be published because the dataverse it is in has not been published.

    Optical Pathlength Control Experiment on JPL Phase B Testbed
    Apr 19, 1993
    Rahman, Z.; Spanos, J.; O'Brien, J.; Chu, C., 1993, "Optical Pathlength Control Experiment on JPL Phase B Testbed", https://hdl.handle.net/2014/34901, La Jolla, California, USA, JPL Open Repository
    An experimental implementation of a nanometer level optical pathlength control for large baseline space interferometry is presented. The pathlength compensation system is installed on a large flexible experimental truss, thus structural motions play a dominant role in the control...
    Adaptive Adjustment of a Precision Truss Structure: Experimental Validation

    An experimental investigation was made to study the impact damage tolerance of thin wall composite struts made of both brittle epoxy and toughtened epoxy based composite materials.
    Transient Temperature Behavior of a Sphere Heated by Microwaves
    Apr 18, 1993
    Jackson, H.W.; Barmatz, M.; Wagner, P., 1993, "Transient Temperature Behavior of a Sphere Heated by Microwaves", https://hdl.handle.net/2014/35091, Cincinnati, Ohio, USA, JPL Open Repository
    We have developed a model for microwave heating of a sphere in a rectangular resonant cavity. The model calculates transient temperature distributions within a sphere during the approach to steady state conditions or on the path to thermal runaway.
    Application of Boltzmann-Ehrenfest Principle to Containerless Microwave Processing in Microgravity

    Bothun, Gregory D.; Schombert, James M.; Impey, Christopher D.; Sprayberry, David; McGaugh, Stacy S., 1993, "The Small Scale Environment of Low Surface Brightness Disk Galaxies", https://hdl.handle.net/2014/35041, USA, JPL Open Repository
    We use a sample of ~340 low surface brightness (LSB) disk galaxies with measured redshifts in combination with the Center for Astrophysics redshift survey to test the hypothesis that LSB galaxies have a deficit of nearby companion galaxies compared to high surface brightness (HSB...
    Noise and Electrical Characteristics below 10 K of small CHFET Circuits and Discrete Devices
