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 includes 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.

    The molecular first hyperpolarizabilities of a series of asymmetric squaraine dyes were measurd by electric-field-induced second harmonic generation; the dyes have negative **-values whose magnitudes are comparable to 4-N,N-dimethylamino-4'-nitrostilbene (DANS).
    Component Selection, Accelerated Testing, and Improved Modeling of AMTEC Systems for Space Power (abstract)
    Jan 1, 1993
    Williams, R. M.; Jeffries-Nakamura, B.; Ryan, M. A.; Underwood, M. L.; Suitor, J.; O'Connor, D., 1993, "Component Selection, Accelerated Testing, and Improved Modeling of AMTEC Systems for Space Power (abstract)", https://hdl.handle.net/2014/35264, Atlanta, GA, JPL Open Repository
    Alkali metal thermal to electric converter (AMTEC) designs for space power are numerous, but selection of materials for construction of long-lived AMTEC devices has been limited to electrodes, current collectors, and the solid electrolyte. AMTEC devices with lifetimes greater tha...
    TOPEX Microwave Radiometer Thermal Control: Post-System-Test Modifications and On-Orbit Performance
    Jan 1, 1993
    Lin, Edward I., 1993, "TOPEX Microwave Radiometer Thermal Control: Post-System-Test Modifications and On-Orbit Performance", https://hdl.handle.net/2014/35320, ['Journal of Spacecraft and Rockets', 'AIAA: 28th Thermo Physics Conference', 'Orlando, FL'], JPL Open Repository
    The Topex Microwave Radiometer has had an excellent thermal performance since launch. The instrument, however, went through a hardware modification right before launch to correct for athermal design inadequacy that was uncovered during the spacecraft thermal vacuum test. This pap...
