The use of a nonhomogeneous aerogel radiator, i.e. one consisting of layers with different refractive indices, has been shown to improve the resolution of the Cherenkov angle measured with a proximity focusing RICH detector. In order to obtain further information on the performance of such a detector, a simple model has been used to calculate the resolution and search for optimal radiator parameters.
Developing a silica aerogel radiator for the HELIX ring-imaging Cherenkov system
本文报道了在我们实验室采用针式干燥技术批量生产96瓦的第一批硅气凝胶契连科夫辐射器的成功制造。气凝胶将用于计划中的球载宇宙射线观测计划HELIX(高能光同位素实验)光谱仪中的环形成像切伦科夫探测器。总共36块透明的疏水气凝胶砖,折射率为1.16,尺寸为10 cm $\times $ 10 cm $\times $ 1 cm,将被选为飞行散热器。到目前为止,48块瓷砖中的40块被确认为没有瓷砖开裂。在第一次筛选中,根据基本的光学测量结果,前16个瓦片中的8个被接受为飞行合格的候选者。为了将气凝胶瓷砖安装到散热器支撑结构中,使用水射流切割装置成功地修剪了先前制造的原型瓷砖。
