Rediscovered photographs of J. Robert Oppenheimer’s 1964 visit to LANL
National Security Research Center staff recently rediscovered a trove of images of J. Robert Oppenheimer’s last known visit to the Laboratory, tucked away among the NSRC’s collections of millions of classified and unclassified photographs and not seen for over thirty years. Oppenheimer, who served as our first Director from 1943–1945, led the United States’ successful wartime effort to develop the world’s first atomic weapons in just 27 months. He left the Lab shortly after World War II ended, but came back in May of 1964 to deliver a lecture about Niels Bohr at the Civic Auditorium (now Duane Smith Auditorium) and visit the Los Alamos Scientific Laboratory Museum (which would become the Bradbury Science Museum), as is captured in these photos.

Phase 1 of the near term hybrid passenger vehicle development program
In order to meet project requirements and be competitive in the 1985 market, the proposed six-passenger vehicle incorporates a high power type Ni-Zn battery, which by making electric-only traction possible, permits the achievement of an optimized control strategy based on electric-only traction to a set battery depth of discharge, followed by hybrid operation with thermal primary energy. This results in a highly efficient hybrid propulsion subsystem. Technical solutions are available to contain energy waste by reducing vehicle weight, rolling resistance, and drag coefficient. Reproaching new 1985 full size vehicles of the conventional type with hybrids of the proposed type would result in a U.S. average gasoline saving per vehicle of 1,261 liters/year and an average energy saving per vehicle of 27,133 MJ/year.

Phase 1 of the near team hybrid passenger vehicle development program. Appendix C: Preliminary design data package, volume 1
The methodology used for vehicle layout and component definition is described as well as techniques for system optimization and energy evaluation. The preliminary design is examined with particular attention given to body and structure; propulsion system; crash analysis and handling; internal combustion engine; DC motor separately excited; Ni-Zn battery; transmission; control system; vehicle auxiliarries; weight breakdown, and life cycle costs. Formulas are given for the quantification of energy consumption and results are compared with the reference vehicle.

Phase 1 of the near term hybrid passenger vehicle development program. Appendix B: Trade-off studies. Volume 2: Appendices
The SPEC '78 computer program which consists of mathematical simulations of any vehicle component and external environment is described as are configuration alternatives for the propulsion system. Preliminary assessments of the fundamental characteristics of the lead-acid and sodium-sulfur batteries are included and procedures are given for estimating the cost of a new vehicle in mass production.

Phase 1 of the near team hybrid passenger vehicle development program. Appendix C: Preliminary design data package. Volume 2: Appendices
The design, development, efficiency, manufacturability, production costs, life cycle cost, and safety of sodium-sulfur, nickel-zinc, and lead-acid batteries for electric hybrid vehicles are discussed. Models are given for simulating the vehicle handling quality, and for finding the value of: (1) the various magnetic quantities in the different sections in which the magnetic circuit of the DC electric machine is divided; (2) flux distribution in the air gap and the magnetization curve under load conditions; and (3) the mechanical power curves versus motor speed at different values of armature current.
