DEVELOPMENT OF A SYSTEM FOR EXCITING GAS MOLECULES BY LOW-ENERGY ELECTRONS,

Abstract

A study and development of a prototype system for exciting a beam of neutral gas molecules by low-energy electrons is presented in this report. The system described is a cylindrically symmetric electron gun which can direct 1 to 10 e V electrons through a pulsed gas beam having a flux of 10 to the 19th power molecules/sec. At 10 e V an electron current in excess of 6mA is regularly observed, while at 4 eV the current is in excess of 1mA. The entire system has internal optics for detecting infrared radiation from the excited molecules as they pass through a well-defined region of space. (Author)
