Operation SUN BEAM - Shot Little Feller I. Project Officers' Report - Project 8.1. High Time Resolution of the First Thermal Pulse,

Abstract

The primary objective of the measurements program was to obtain the general shape of the first pulse in four wavelength regions designated as ultra-violet, visible, near-infrared, and broadband. A secondary objective was to determine the ratio of direct to scattered radiation for the first pulse in the same wavelengths regions. Procedure was to attenuate and spectrally limit incoming radiation to various photo-detectors whose electrical outputs were amplified and recorded on oscilloscope cameras and sometimes on magnetic tape. The general shape of the first pulse of thermal radiation from the Little Feller I event was measured in three wavelength regions. Instrumentation for measuring the ratio of direct to scattered radiation was saturated and no data was obtained. This is an NTPR(Nuclear Test Personnel Review report.
