ABC's of pion charge exchange. [Absorption, blocking, and correlations] (open access)

ABC's of pion charge exchange. [Absorption, blocking, and correlations]

Calculations of pion single charge exchange using the PWIA and DWIA are presented. Emphasis is given to the effects of absorbtion and blocking. A microscopic calculation of the 0/sup 0/ excitation and low energy angular distribution is in excellent agreement with the data. A fixed nucleon multiple scattering calculation of the pion double charge exchange reaction is presented. Various valence neutron wave functions are used, and the contributions of different spatial orientations of the last two neutrons to the reaction are examined. The DCX cross section is found to be very sensitive to the inclusion of correlations in the two-neutron wave function. Satisfactory agreement with DCX data on /sup 14/C can be obtained using a nucleonic picture of the nucleus.

Abort kicker power supply systems at Fermilab (open access)

Abort kicker power supply systems at Fermilab

Over the past several years, Fermilab has been operating with a single turn proton abort system in both the superconducting Tevatron and the conventional Main Ring. The abort kicker power supply for this system discharges a lumped capacitance into the inductive magnet load, causing the beam to enter the abort channel. The characteristics of this current waveform are defined by the requirements of the machine operation. The standard fixed target running mode calls for 12 booster batches of beam which leaves a rotating gap in the beams of approx.1.8 ..mu..s. The current waveform is required to rise to 90% of I/sub max/ in this time to avoid beam loss from partially deflected beam. Aperture limitations in both the accelerator and the abort channel demand that the current in the magnets stays above this 90% I/sub max/ for the 21 ..mu..s needed to ensure all the beam has left the machine. The 25 mm displacement needed to cleanly enter the abort channel at 1 TeV corresponds to a maximum current in each of the 4 modules of approx.20 kA. Similar constraints are needed for the Main Ring and Tevatron antiproton abort systems. A unique feature of this design is the high …

Absolute Wavelength Measurement and Fine Structure Determination in /Sup 7/Li Ii (open access)

Absolute Wavelength Measurement and Fine Structure Determination in /Sup 7/Li Ii

The energy levels of two-electron atoms continue to provide rigorous tests of relativistic quantum theory, and of correlation effects within a multi-particle system. These interactions are determined perturbatively, with several approximations, and theoretical results often differ. It is critical to provide precise measurements of absolute wavelengths connecting these atomic energy levels to obtain a resolution of the precision of the different parts of such complex calculations. In this work, we report a high precision optical measurements in the 1s2s /sup 3/S - 1s2p /sup 3/P multiplet of Li II using fast-beam laser spectroscopy. A collinear interaction using both parallel and antiparallel laser and ion beams allows both for precise elimination of large Doppler shifts, and for a strong kinematic narrowing of the observed resonances, as compared with thermal beam experiments. The wavelengths of the observed resonance fluorescence radiation are determined by comparing them with simultaneously recorded saturated absorption profiles of molecular iodine hyperfine components. In turn, the absolute wavelengths of the iodine lines are obtained from precisely calibrated Fabry-Perot etalon fringes in a separate experiment. The final precision of the Li II wavelengths is 5 parts in 10/sup 9/, which is at a level of precision of 80 ppM of …

Absorption spectra of shocked liquid CS/sub 2/ (open access)

Absorption spectra of shocked liquid CS/sub 2/

The importance of shock initiation of high explosives (HE) was understood as early as 1863 when Alfred Nobel introduced the detonator as a means of detonating nitroglycerine. The critical pressure rise times required to achieve shock initiation and steady propagation of detonation are determined by the chemical and mechanical properties of an explosive. Although progress has been made in the understanding of the effects of mechanical properties, the detailed effects of high pressures on chemical reaction mechanisms are still only poorly understood. This paper reports the results of two experiments using CS/sub 2/, which is known to undergo electronic state transitions when shocked to high pressures. The goal of these experiments was to examine the known shock-generated expansion of CS/sub 2/ absorption bands while generating the shocks with a flyer plate system driven by high explosives.

Abundance and Distribution of Walleye, Northern Squawfish, and Smallmouth Bass in John Day Reservoir, 1984-1985 Progress Report. (open access)

Abundance and Distribution of Walleye, Northern Squawfish, and Smallmouth Bass in John Day Reservoir, 1984-1985 Progress Report.

Sampling was conducted in John Day Reservoir to collect walleye, northern squawfish and smallmouth bass. Changes in distributions during sampling were characterized from changes in catch per unit effort (CPUE) in sampling areas. Observed movements of marked and radiotagged fish were examined and used to define discrete populations. Abundances were estimated using a modified Schnabel multiple mark and recapture estimator. Abundance estimates were corrected for angler harvest, size specific vulnerability to gear, recruitment due to growth and tag loss during sampling. Age composition of catch was determined to characterize relative contributions of various year classes to the populations. Ages at which fish were fully recruited to gear were defined by catch curves. Survival of fully recruited year classes was calculated from differences in CPUE's between 1984 and 1985. Mean length at age was estimated and used to determine age specific incremental growth. Eighty-eight percent of walleye were caught in McNary tailrace or Irrigon-Paterson, whereas 95% of smallmouth bass were caught from Irrigon-Paterson to the John Day forebay. Abundances of walleye and northern squawfish with fork lengths greater than 250 mm and smallmouth bass with fork lengths greater than 200 mm were estimated to be 16,219, 95,407, and 11,259. Anglers harvested …
