چکیده
Atlas is a facility being designed at Los Alamos National Laboratory (LANL) to perform high energy-density experiments in support of weapon-physics and basicresearch programs. It is designed to be an international user facility, providing experimental opportunities to researchers from national laboratories and academic institutions. For hydrodynamic experiments, it will be capable of achieving a pressure exceeding 30-Mbar in a several cm volume. With the development of a suitable opening switch, it will be capable of producing more than 3-MJ of soft xrays. The capacitor bank design consists of a 36-MJ array of 240-kV Marx modules. The system is designed to deliver a peak current of 45to 50-MA with a 4to 5μs risetime. The Marx modules are designed to be reconfigured to a 480-kV configuration for opening switch development. The capacitor bank is resistively damped to limit fault currents and capacitor voltage reversal. An experimental program for testing and certifying prototype components is currently underway. The capacitor bank design contains 300 closing switches. These switches are a modified version of a railgap switch originally designed for the DNA-ACE machines. Because of the large number of switches in the system, individual switch prefire rates must be less than 10-4 to protect the expensive target assemblies. Experiments are underway to determine if the switch-prefire probability can be reduced with rapid capacitor charging. LA-UR-96-3440 Revised 2/11/97

I first review a) the flowering of coherent states in the 1960’s, yet b) the discovery of coherent states in 1926, and c) the flowering of squeezed states in the 1970’s and 1980’s. Then, with the background of the excitement over the then new quantum mechanics, I describe d) the discovery of squeezed states in 1927.

This talk summarizes results for all the scale independent renormalization constants for bilinear currents (ZA, ZV , and ZS/ZP ), the improvement constants (cA, cV , and cT ), the quark mass dependence of ZO , and the coefficients of the equation of motion operators for O(a) improved lattice QCD. Using data at β = 6.0, 6.2 and 6.4 we study the scaling behavior of these quantities and quantify r...
متن کاملLA - UR - 97 - 2330 Nuclear Sizes and the Isotope Shift
Darwin-Foldy nuclear-size corrections in electronic atoms and nuclear radii are discussed from the nuclear-physics perspective. Interpretation of precise isotope-shift measurements is formalism dependent, and care must be exercised in interpreting these results and those obtained from relativistic electron scattering from nuclei. We strongly advocate that the entire nuclear-charge operator be u...
