Long-pulse KrCl laser with a high discharge quality \ud
The discharge quality and optimum pump parameters of a long-pulse high-pressure gas discharge excited KrCl laser are investigated. A three-electrode prepulseâmainpulse excitation circuit is employed as pump source. The discharge volume contains a gas mixture of HCl/Kr/Ne operated at a total pressure of up to 5 bar. For a planeâplane resonator, the divergence of both output laser beams is measured. A low beam divergence of less than 1 mrad is measured as a result of the very high discharge homogeneity. A maximum laser pulse duration of 150 ns (FWHM) is achieved for a pump duration of 270 ns (FWHM) and a power density of 340 kWâcm-3. Pumping the discharge under optimum conditions employing a stable resonator results in a maximum specific energy of 0.45 J/l with a laser pulse duration of 117 ns and an efficiency of 0.63% based on the deposited energy

Fundamental studies on semiconductor radiation detectors Second annual status report, 1 Mar. 1965 - 28 Feb. 1966
Temperature dependence of resolution and response function of lithium drifted silicon detectors to monoenergetic electron
Fundamental properties of semiconductor materials, and material performance in detectors
Procedures for determining fundamental properties of semiconductor materials, their performance as radiation detectors, and their service life as such detectors are given. Relationships were established between the minority carrier lifetime in the bulk of the material and the charge collection efficiency of the detector
A âhealthy babyâ: The double imperative of preimplantation genetic diagnosis
This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2010 The Authors.This article reports from a study exploring the social processes, meanings and institutions that frame and produce âethical problemsâ and clinical dilemmas for practitioners, scientists and others working in the specialty of preimplantation genetic diagnosis (PGD). A major topic in the data was that, in contrast to IVF, the aim of PGD is to transfer to the womanâs womb only those embryos likely to be unaffected by serious genetic disorders; that is, to produce âhealthy babiesâ. Staff described the complex processes through which embryos in each treatment cycle must meet a double imperative: they must be judged viable by embryologists and âunaffectedâ by geneticists. In this article, we focus on some of the ethical, social and occupational issues for staff ensuing from PGDâs double imperative.The Wellcome Trus
