Preliminary reentry safety assessment of the General Purpose Heat Source module for the Cassini mission: Aerospace Nuclear Safety Program

As asked by the U. S. Department of Energy/Office of Special Applications, and in support of the Environmental Impact Statement for the Cassini mission, The Johns Hopkins University/Applied Physics Laboratory (JHU/APL) has conducted preliminary one-dimensional ablation and thermal analyses of the General Purpose Heat Source (GPHS). The predicted earth entry conditions provided by the Jet Propulsion Laboratory (JPL) for a Cassini Venus-Venus-Earth-Jupiter Gravity Assist (VVEJGA) trajectory were used as initial conditions. The results of this study which constitute the initial reentry analysis assessment leading to the Cassini Updated Safety, Analysis Report (USAR) are discussed in this document.

Studies of relativistic heavy ion collisions. Annual progress report, August 1, 1992--July 31, 1993 (open access)

Studies of relativistic heavy ion collisions. Annual progress report, August 1, 1992--July 31, 1993

With the completion of the experimental runs with the DLS, which included both heavy ion and nucleon projectiles and targets, is being completed the analysis of these high statistics experiments. The Hopkins group has a major responsibility in comparing the experimental results with recently developed simulation codes for a theoretical comparison. The second major activity involves the STAR experiment at RHIC, to continued involvement with simulations and development of prototypes of detector systems is expected. The program for studying optical properties of mirrors and gas scintillations related to Cerenkov ring imaging will continue.

STAR Electromagnetic Calorimeter R&D Progress Report, 1 October 1992--31 August 1993 (open access)

STAR Electromagnetic Calorimeter R&D Progress Report, 1 October 1992--31 August 1993

A lead-scintillator sampling electromagnetic calorimeter (EMC) is planned as an upgrade to the STAR detector for the RHIC Accelerator at Brookhaven National Laboratory (BNL). Considerable work on the conceptual design of the calorimeter, and related interfacing issues with the solenoids magnet and the time projection chamber (TPC) subsystems of STAR occurred in the period 1 October 1992 to 31 August 1993 (FY 1993). This report documents and summarizes the conclusions and progress from this work.
