SOLAR X RAYS FROM 3 TO 12 ANGSTROMS AS MEASURED WITH A PROPORTIONAL COUNTER SPECTROMETER.

Abstract

A sealed proportional counter with a 1.1 mg/sq cm window was used with a five-step integral pulse-height analyzer to measure the x-ray flux from the quiet sun. The instrument was flown on an Aerobee sounding rocket from White Sands Missile Range, New Mexico, on 25 October 1962 and 2 May 1963. A description of the construction and calibration of the equipment is given, and a detailed discussion of the interpretation of the data is presented. The resulting spectrum, if interpreted as a bremsstrahlung continuum, is characterized by a 3.5 million degree electron temperature, and has an intensity at earth distance of .00012 erg /sq cm sec shorter than 8 A, and .0025 erg/sq cm sec between 8 and 20 A.
