D. Blyth, R. Alarcon, R. Begag, J. Holmes, J. Stryker

摘要:

具有1.01至1.07的折射率的新型高度透明的疏水二氧化硅气凝胶已经由Aspen Aerogels,Inc.和选择瓷砖已测试使用电子束在DESY,汉堡设施。为了评估气凝胶的目的,设计并构建了漫反射阈值切伦科夫计数器,并且其可以容纳高达20 cm × 20 cm的气凝胶瓦片面积。使用新的气凝胶作为切伦科夫辐射器的计数器的性能的测量给出的光电子产额和品质因数。

英文摘要:

New highly transparent, hydrophobic silica aerogels with refractive indices of 1.01 to 1.07 have been produced by Aspen Aerogels, Inc., and select tiles have been tested using an electron beam at the DESY, Hamburg facility. A diffusively-reflective threshold Cerenkov counter was designed and constructed for the purpose of evaluating the aerogels, and can accommodate aerogel tile areas of up to 20 cm by 20 cm. Measurements of the performance of the counter using the new aerogels as Cerenkov radiators are given in terms of photoelectron yields and a figure of merit.
