 | JASON has been tasked by the Army to review recent progress in infrared detector technology and to update the earlier JASON report "Imaging Infrared Detectors" (JSR-91-600). To this end, a workshop was conducted during the 1997 Summer Study with distinguished participants drawn from industry, academia, and government, listed in Appendix D. Through discussions with workshop participants and the JASONs an updated overview of the state of imaging infrared detector technology ... |

| In this report, we examine the options for launching small payloads to Low Earth Orbit (LEO). "Small" is taken as, approximately, m(p)=1OO 1bm, or perhaps a small multiple of that. Various launch Options are considered; including single- and multi-stage, ground- and air-launched rockets, as well as the potential advantages of an intermediate airbreathing boost stage. Fundamental constraints between payload-to-total mass ratio, in a variety ... |

| JASON undertook a study at DARPA's request to look for new opportunities for progress in the detection and characterization of UGFs. Part of our charge was to identify the most promising technology areas for investment, emphasizing standoff and covert sensor techniques. The study therefore surveyed a wide range of approaches, and we received numerous briefings. These included summaries of the technology programs of various agencies and briefings from organizations and ... |

| The Department of Energy and its three weapons laboratories (LANL, LLNL, and SNL) have developed a Stockpile Stewardship and Management Program (SSMP) in response to their designated mission of maintaining an effective, i.e. reliable and safe, nuclear deterrent without underground nuclear tests (UGTs). The need to ensure the effectiveness of an aging stockpile presents new challenges of major importance. In this study we review what is known about the aging ... |

|
| This report contains the results of the JASON summer study review of the ONR Advanced Capability Initiative (ACI) in Wide Area Surveillance and Fire Control Quality Tracking. The mission of this ACI is to identify and develop advanced technologies needed for new ship and airborne search, tracking and illumination radars that would give ships a more effective self defense capability against very low altitude cruise missiles and aircraft. |

|
| A recent proposal to use electrostatic forces to lift and propel a small airborne vehicle is examined. We show here that although this is permitted by the laws of physics, it is very inefficient, and is limited to low areal loads by the requirement to avoid electric breakdown. Electrostatic propulsion offers no special advantages which might justify the price of its inefficiency. |

| A JASON summer study was performed to assess the status of ongoing research programs in the area of energetic materials. The goal of this study was to examine the current status of work in the area of energetic materials in order to provide DARPA with a technical evaluation of which, if any, research approaches have the potential to produce significant advances in the state of the art of this area. ... |

|
| We have shown that hypercarrier modulation with binary on/off keying, and with bit times longer than the whole "ringing time" of the urban environment, is potentially capable of achieving megabit per second data rates in a manner that is completely insensitive to multipath fading. A straw-man design, using current COTS components, has been presented. While we would not want to claim that this design is exactly optimal (or even completely ... |

 | At the request of DOE a subgroup of JASON reviewed the first two subcritical experiments now planned to be performed underground at the Nevada Test Site. The purpose of this review was to ascertain that the two test 5 would indeed remain subcritical. This report also addresses some general comments to the process for planning and approving subcritical experiment in the future. |

| Jason was asked to see if there were any physical principles that would ultimately prevent several new systems from working as intended before major resources were expended. These included: (1) Cavitating vortex bubble rings which are underwater analogs to smoke rings. They can carry energy (in the form of circulating water) over long distances. We concluded that they could not be used as weapons. (2) Detection of very shallow mines ... |
