Measurement of energy deposited by charged-particle beams in composite targets (open access)

Measurement of energy deposited by charged-particle beams in composite targets

We have measured the energy deposited in two types of composite targets by a number of charged-particle beams: targets made of /sup 238/U, Lucite, and polyethylene were exposed to 0.26-GeV protons and 0.33-GeV deuterons, and aluminum-Lucite composites were exposed to 0.5-GeV electrons. In addition, we measured neutrons and gamma rays emitted from solid targets of various materials (including /sup 238/U and iron) exposed to 0.26-GeV protons and 0.33-GeV deuterons. We used passive detectors (thermoluminescence dosimeters, Lexan fission track recorders, and photographic emulsions) to measure the nonfission dose and the fission-fragment dose from the primary beam and its shower of products. Measurements were made at various depths and radial positions in the targets. Plots and numerical values of the measured doses are presented. The emission of neutrons and gamma rays was measured with a liquid-deuterated-benzene detector. In general, the dose profile with depth is similar for 0.26-GeV protons and 0.33-GeV deuterons. The ratio of return neutrons to gamma rays increases with increasing target mass number. Deuterons, however, produce from 1.7 to 5.8 times as many neutrons and gamma rays per particle as do protons.

Least cost planning from a customer's perspective (open access)

Least cost planning from a customer's perspective

In this paper, I offer some thoughts about least cost planning, not from the perspective of the regulator or utility, but from the perspective of a residential customer. The problem that I address is, as a homeowner in northern Virginia, I am about to make a long term fuel choice for my household, where the options include, natural gas, electricity and fuel oil. An additional choice is the energy efficiency capital investment in my home that could decrease my monthly fuel costs. My decision process, hopefully as a rational consumer, offers implications about the efficiency of various services provided by all three fuel suppliers, including the local natural gas distribution companies (LDC).

Some general properties of stimulated Raman propagation with pump depletion, transiency and dispersion (open access)

Some general properties of stimulated Raman propagation with pump depletion, transiency and dispersion

This note considers some of the properties of the Stokes pulse that grows from a specified seed pulse in the presence of a strong pump pulse as it propagates through a dispersive atomic vapor. We first present an generic dimensionless form for the coupled equations that govern the propagation of pump and Stokes fields or collinear plane-wave pulses. By treating the two fields we permit pump depletion. We include transient atomic response (as embodied in the Raman coherence), but neglect changes in atomic populations. (Thus our equations pertain to the regime in which atoms are more numerous than photons). The equations employ a gain length, a dispersion time {tau}{sub dis}, and a Raman coherence time (or memory time) {tau}{sub R} as basic parameters: these two times, together with a single-photon stationary-atom detuning {Delta}, subsume the details of a particular atomic Raman transition and particular operating conditions. (The effects of Doppler shifts enters the equations through the coherence time). We discuss some general properties of these generic Raman propagation equations, and present illustrations of their solutions in the absence of dispersion. We comment on departures from exponential growth. We than show examples of behavior when dispersion is present and the pump …

[Letter from Jack Davis and Bill McCarter to E.A. Carmean, April 2, 1990]

Photocopy of a letter from Jack Davis and Bill McCarter, co-directors of North Texas Institute for Educators on the Visual Arts, to E.A Carmean, Director of the Modern Art Museum of Fort Worth. Thanking him for graciously agree to be chair of the Advisory Committee for the North Texas Institute for Educators on the Visual Arts. Davis and McCarter writes that being a member of the advisory committee they will periodically review the activities of the Institute and serve as liaison between the community and the Institute, which serves as stepping stone towards comprehensive visual arts program being integrated in school districts. Included in the letter are details about what to expect from being a committee member and the types of meetings they hope to have during the following year. Davis and McCarter write that they are excited about the opportunity to improve the quality of visual arts for students and develop a more informed audience. The letter states that enclosed are a list of people who have been invited to participate as committee members as well as a packet of materials that were sent to them. The list and materials are not present with the letter.
