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.

    Numerical Solution of Wave Equations for the Stability of Inner Cometo-Sheath
    Jan 1, 1993
    Srivastava, K.; Tsurutani, B.; Goldstein, B., 1993, "Numerical Solution of Wave Equations for the Stability of Inner Cometo-Sheath", https://hdl.handle.net/2014/34851, UNKNOWN, JPL Open Repository
    Numerical solution of the MHD wave equations for stability of the cometary sheath determined by the balance between the inward Lorentz body force and the outward ion-neutral drag force is obtained by using a two-point boundary value method.
    Fluorescene of Buckminsterfullerenes: UV Emission of C<sub>60</sub><sup>+</sup> and C<sub>70</sub><sup>+</sup>
    Jan 1, 1993
    Trajmar, S.; Wang, S.; Man, K.F.; Khakoo, M.A., 1993, "Fluorescene of Buckminsterfullerenes: UV Emission of C60+ and C70+", https://hdl.handle.net/2014/34907, UNKNOWN, JPL Open Repository
    We report the first observation of UV luminescence from gaseous C60+ and C70+ buckminsterfullerenes. The emission features appear in the 275 to 340 nm wavelength region and originate from radiative decay of the excited ionic species.

    Electron Microscopy of Natural and Epitaxial Diamond
    Jan 1, 1993
    Posthill, J. B.; George, T.; Malta, D. P.; Humphreys, T. P.; Rudder, R. A.; Hudson, G. C.; Thomas, R. E.; Markunas, R. J., 1993, "Electron Microscopy of Natural and Epitaxial Diamond", https://hdl.handle.net/2014/35249, Journal of the Microscopy Society of America, JPL Open Repository
    Semiconducting diamond films have the potential for use as a material in which to build active electronic devices capable of operating at high temperatures or in high radiation environments. Ultimately, it is preferable to use low-defect-density single crystal diamond for device...
