Improved Approach to Characterizing and Presenting Streak Camera Performance

The performance of a streak camera recording system is strongly linked to the technique used to amplify, detect and quantify the streaked image. At the Lawrence Livermore National Laboratory (LLNL) streak camera images have been recorded both on film and by fiber-optically coupling to charge-coupled devices (CCD's). During the development of a new process for recording these images (lens coupling the image onto a cooled CCD) the definitions of important performance characteristics such as resolution and dynamic range were re-examined. As a result of this development, these performance characteristics are now presented to the streak camera user in a more useful format than in the past. This paper describes how these techniques are used within the Laser Fusion Program at LLNL. The system resolution is presented as a modulation transfer function, including the seldom reported effects that flare and light scattering have at low spatial frequencies. Data are presented such that a user can adjust image intensifier gain and pixel averaging to optimize the useful dynamic range in any particular application.

Radiological assistance program: Region I. Part I (open access)

Radiological assistance program: Region I. Part I

The purpose of the Radiological Assistance Program (RAP) is to make DOE resources available and provide emergency assistance to state and local agencies in order to control radiological hazards, protect the public health and safety, and minimize the loss of property. This plan is an integral part of a nationwide program of radiological assistance established by the US DOE, and is implemented on a regional basis. The Brookhaven Area Office (BHO) Radiological Assistance Program is applicable to DOE Region I, which consists of the New England States, New York, New Jersey, Pennsylvania, Delaware, Maryland and the District of Columbia. The BHO RAP-1 has been developed to: (a) ensure the availability of an effective radiological assistance capability to ensure the protection of persons and property; (b) provide guidelines to RAP-1 Team personnel for the evaluation of radiological incidents and implementation of corrective actions; (c) maintain liaison with other DOE installations, Federal, State and local organizations which may become involved in radiological assistance operations in Region I; and (d) encourage development of a local capability to cope with radiological incidents.
