JOURNAL FREE ACCESSThe infrared absorption in widnow materials such as NaCI, KBr, and Kul, which are commercially availanle in Japan, has been studied by means of thecalorimetric technique with a step-tunable CW CO2 maser. The absorptlon coeficientat10.6μm of NaCl is measured to be 2.5×10-3 cm-1, which is almost twice of theintrinsic multiphonnn absorption. KCI material has the10.6μ m absorption coefficientof 6×10-4 cm-1, which is about one ordex higher than the intrinsic multiphononabsorption coefficient of 7×10-5 cm-1. For KBr, the absorption coefficient at 10.6μ mis 1×10-3 cm-1, which is about four order higher than the intrinsic multiphononabsorption of 2×10-7 cm-1. (One absorption band at 9.29 μm is observed ln KBr) Three different techniques are tried to separate out bulk and surface absorption.This calorimetric technique is used to obtain the dependence of absorption coefficienton the sample's position in an NaCI ingot.View full abstractDownload PDF (1105K) -

JOURNAL FREE ACCESSA cold cathode gun of high current pulsed electron beam was investigated for an eventualuse as a CO2 laser discharge sustainer.Measured performance characteristics, suchas gun impedance, gun current behaviors as a function of applied voltage and cathodematerlal Ta and Ti were consistent with the pnasma cathode model using the evapoiationof cathode metal. The electron beam current was determined by the space chargelimited flow from the expanding plasma cathode surface.The maximum current densitywas determined by the electron satumtion current on the cathode plasma surface. By the fandamental investigations, optimum design for a large apature and uniform electronbeam source are presented.View full abstractDownload PDF (860K) -
