Automated Emergency Response (ER) systems are playing a greater role in providing prompt and reliable predictions of the impact of inadvertent releases of hazardous materials to the environment. Observed and forecast environmental and accident source term data are input into environmental transport and dispersion models to provide dosimetry estimates used as decision making aids for responding to emergencies. Several automated ER systems have been developed for US Federal Government facilities and many are available commercially. For such systems to be useful, they must reliably and consistently deliver a timely product to the decision makers. Evaluation of the entire ER system is essential to determine the performance that can be expected from the system during an emergency. Unfortunately, seldom are ER systems evaluated as a whole. Usually Quality Assurance programs evaluate the performance of individual components of the system. Most atmospheric pollution model evaluation methods usually involve an evaluation of the predictive performance of the transport and dispersion model when compared either with experimental tracer results or results from other models. Rarely, however, is the ability of the ER system to provide timely, reliable and consistent information evaluated. Such an evaluation is vital to determine the system performance during an emergency …

This workshop on Siberian snakes for the SSC was held to discuss the technical feasibility of polarized beams at the SSC. Only the 20-TeV collider ring was discussed with the prospect that the polarized beam source, the linac, and the boosters have fewer technical problems. More specifically, the major issue of the miniworkshop was to give an answer to the questions (1) how many Siberian snakes are needed and (2) what alignment tolerances are required, given the snakes. No attempt was made to address the issues of whether polarized beams will benefit the SSC high energy physics program or what the cost will be. As for the two questions above, workshop participants concluded that the required number of snake pairs is around 10 and the alignment tolerance is less than 100 microns. This tight tolerance is of great concern and has to be confirmed by other means such as computer simulation. One of the conclusions was that they should have a realistic lattice of the SSC which enables them to study it in more detail and to try computer simulations.
