| Popis: |
As-fabricated free-standing indium foils were found to have transmission in the 90nm to 120nm band ranging from 10% to 70% of modeled values based on pure indium. Auger depth profiling of the as-deposited indium showed little surface contamination and high purity. However, final freestanding filters were found to have heavy contamination, particularly on the surface. An argon/hydrogen plasma bombardment was developed which improved EUV transmission by 50% to 500% in the finished filters without causing significant pinholes to develop in the foils or appreciably affecting blocking characteristics. |
