Kapton ion chamber

WebbAbstract. Electret ion chamber (EIC) is a passive integrating ionization chamber used extensively for measuring technologically enhanced radioactivity. Commercially available electret ion chambers called ^-PERJVI® (Electret-Passive Environmental Radiation Monitors) electret ion chambers are relatively new and are in use only from the past 10 ... WebbAn atomic oxygen Ion beam, accelerated from a tunable microwave resonant cavity, was used at Lewls Research Center to bombard samples of the widely used polyimide Kapton. The Kapton experienced degradation and mass loss at high rates, which may be comparable to those found in Space Shuttle operations
