Development of a Heating and Humidifying Chamber for In-Situ Synchrotron Radiation Analysis under Controlled High Temperature and Humidity Conditions

Abstract

It difficult to elucidate functional mechanisms and ensure performance when evaluating devices under high temperature and humidity conditions solely through samples extracted in normal environments. This study developed a novel heating and humidifying chamber with a control system that enables in-situ synchrotron radiation analysis under these conditions. We evaluated the chamber’s performance and conducted in-situ measurements using iodine-containing polyvinyl alcohol films. X-ray absorption spectra were measured from room temperature to 80°C and from 0 % to 80 % relative humidity. Unlike conventional room temperature humidification, this method allows for realistic high temperature and humidity measurements.
