1980年左右，日本高能加速器研究组织，也被称为KEK实验室，开始开发二氧化硅气凝胶作为切伦科夫散热器。1996年，日本千叶大学的高能物理小组与KEK合作开始气凝胶的研究和开发。最先进的切伦科夫探测器的设计是通过提高气凝胶透明度来实现的。与此同时，超高折射率和超低折射率气凝胶被开发出来，以弥补分别用于识别低动量和高动量粒子的可用指数的差距。世界各地正在进行的和未来的粒子物理实验都将采用这些方法。我们报道了气凝胶开发的最新结果，并将其应用于门限型和环形成像切伦科夫探测器。
Around 1980, Japan's High Energy Accelerator Research Organization, also known as the KEK laboratory, began developing silica aerogels as a Cherenkov radiator. In 1996, the high energy physics group at Chiba University, Japan, began aerogel research and development in collaborating with KEK. The design of state-of-the-art Cherenkov detectors is enabled by improving aerogel transparency. Simultaneously, ultrahigh-and ultralow-refractive-index aerogels were developed to bridge the gap in the available indices for identifying low-and high-momentum particles, respectively. These are and will be employed in ongoing and future particle physics experiments all over the world. We report the latest results from the aerogel development and applications to threshold-type and ring-imaging Cherenkov detectors.
