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.

    A New Force Balanced Accelerometer Using Tunneling Tip Position Sensing
    Jul 7, 1993
    Zavracky, P.; Hartley, F.; Sherman, N.; Warner, K., 1993, "A New Force Balanced Accelerometer Using Tunneling Tip Position Sensing", https://hdl.handle.net/2014/35346, Yokohama, Japan, JPL Open Repository
    In this paper, we report the initial development of a single-axis bulk micromachined accelerometer. The device employs an electron tunneling tip as a position detector in a force feedback control system. Control electrodes are placed above and below the proof mass and act as elec...
    Kinetics and Mechanism of the CIO + CIO Reaction: Pressure and Temperature Dependences of the Bimolecular and Termolecular Channels andThermal Decomposition of Chlorine Peroxide, CIOOCI
    Jul 7, 1993
    Nickolaisen, Scott L.; Friedl, Randall R.; Stanley P. Sander, 1993, "Kinetics and Mechanism of the CIO + CIO Reaction: Pressure and Temperature Dependences of the Bimolecular and Termolecular Channels andThermal Decomposition of Chlorine Peroxide, CIOOCI", https://hdl.handle.net/2014/35519, USA, JPL Open Repository
    The kinetics and mechanism of the CIO + CIO reaction and the thermal decomposition of CIOOCI were studied using the flash photolysis/long path ultraviolet absorption technique. Pressure and temperature dependences were determined for the rate coefficients for the bimolecular and...
    Masses and Densities of Pluto and Charon
    Jul 6, 1993
    Null, G.; Owen, W.; Synnott, S., 1993, "Masses and Densities of Pluto and Charon", https://hdl.handle.net/2014/35325, ['Pluto and Charon Open Meeting', 'Flagstaff, Arizona, USA'], JPL Open Repository
    We have analyzed Hubble Space Telescope Wide Field Camera CCD images of Pluto, Charon, and a background star, obtained on seven HST visits over a 3.2 day span in August 1991, to observe Pluto's barycentric motion and to determine the individual masses and bulk densities of Pluto...
    Thermal Systems Design and Analysis for a 10K Sorption Cryocooler Flight Experiment

    The design, analysis and predicted performance of the Brilliant Eyes Ten-Kelvin Sorption Cryocooler Experiment (BETSCE) is described from a thermal perspective...
    (abstract) The Impactor Flux in the Pluto-Charon System
    Jul 6, 1993
    Weissman, Paul R.; Stern, S. Alan, 1993, "(abstract) The Impactor Flux in the Pluto-Charon System", https://hdl.handle.net/2014/35453, Flagstaff, AZ, JPL Open Repository
    The impactor flux on Pluto and Charon consists of long-period comets from the Oort cloud passing through the region, and intermediate-period comets evolving inward to (or outward from) short-period orbits. The source of the intermediate-period comets is likely an extended disk of...
    High-Frequency Orographically Forced Variability in a Single-Layer Model of the Martian Atmosphere

    Coupling Finite Element and Integral Equation Representations To Efficiently Model Large Three-Dimensional Scattering Objects
    Jul 1, 1993
    Cwik, Tom; Jamnejad, Vahraz; Zuffada, Cinzia, 1993, "Coupling Finite Element and Integral Equation Representations To Efficiently Model Large Three-Dimensional Scattering Objects", https://hdl.handle.net/2014/34814, USA, JPL Open Repository
    The usefulness of finite element modeling follows from the ability to accurately simulate the gemetry and three-dimensional fields on the scale of a fraction of a wavelength. To make this meodelling practical for engineering design,it is necessary to integrate the stages of geome...
