X射线照射岩盐中能量沉积物对微波的反射：超高能盐中微子探测器作用类似于无线电泡室的意义
Reflection of microwave from energy deposit by X-ray irradiation in rock salt: Implication of an ultra high energy salt neutrino detector to act like a radio bubble chamber
摘要：
GZK中微子（超高能中微子）的存在是合理的，虽然流量很低。需要一种新的方法来使用巨大质量的检测器介质来检测它们。本文对用X射线照射小岩盐样品，测量电磁能矿床微波反射率的雷达方法进行了基础研究。在1 × 10 ^19 eV的能量沉积下，发现反射率为1 × 10 ^-6，与X射线强度的平方成正比，表明该效应是相干散射。反射的衰减时间是几秒钟。这种效应意味着可以利用大规模的天然岩盐地层，像一个泡室一样，用无线电波代替可见光照射来探测GZK中微子。
英文摘要：
Existence of GZK neutrinos (ultra high energy neutrinos) have been justified although the flux is very low. A new method is desired to use a huge mass of a detector medium to detect them. A fundamental study of radar method was carried out to measure microwave reflection from electromagnetic energy deposit by X-ray irradiation in a small rock salt sample. The reflection rate of 1x10^-6 was found at the energy deposit of 1x10^19 eV which was proportional to square of the X-ray intensity suggesting the effect to be coherent scattering. The decay time of the reflection was several seconds. This effect implies a large scale natural rock salt formation could be utilized like a bubble chamber irradiated by radio wave instead of visible light to detect GZK neutrinos.
