论文摘要
直接检测暗物质,继续避免科学家的许多尝试相互作用,直到今天,我们知道它是通过观察到的引力效应而知道的唯一方法。许多搜索实验是在搜索暗物质直接观察的点受到地球上太阳中微子背景信号的限制。过去的实验通常使用大容量的中央检测器,以寻找能量在检测器体积内实现的,该探测器体积与通过周围的活动源阵列和被动屏蔽的任何粒子的任何轨道无关。将在这里提出一种新的替代方法,可以通过更改与太阳的距离进行搜索,以通过可预测的方式从观察中删除1/r $^2 $法律的距离。在航天器上或在小行星内建造的暗物质检测器可能是可能的。航天器可以很容易地到达地球小行星近地球小行星,通常有通往金星轨道的路径,几乎可以进入木星的轨道。这些小行星是由冰制成的,例如克里特岛,一堆松散的巨石和卵石,或两者的组合。降落在小行星上,在小行星上可以在地表下融化小行星在地面下融化,主要是用冰制造的,或者将其爪子捕捞到小行星中可以提供两个优势:从宇宙和伽马射线中屏蔽,以及融化的冰块以及进入小行星的冰块可能会成为更大的暗物质检测器的一部分。这两个优点都将使黑物质检测器比地球上的航天器带来的深色物质检测器要大得多。
Direct detection of dark matter continues to elude scientists' many attempts to see it interact, and still to this day the only way we know it is there is through observed gravitational effects. The many search experiments are at the point where the search for dark matter direct observation is limited by the solar neutrino background signal here at Earth. Past experiments typically use a large volume central detector looking for energy materializing inside a detector volume that is not associated with any tracks of particles entering the volume through the surrounding active veto array and passive shielding. Here will be presented a new alternative method to see dark matter performing a search by changing the distance away from the Sun where the 1/r$^2$ law could be removed from the observations in a known predictable way. A Dark Matter detector on a spacecraft or built inside an asteroid might be possible. Many near Earth asteroids that can be easily reached by a spacecraft often have paths going in to the orbit of Venus and out to almost the orbit of Jupiter. These asteroids are made of ice, such as Crete, rubble piles of loosely bound boulders and pebbles, or a combination of the two. Landing on an asteroid where a space craft could melt its way under the surface for asteroids made mostly of ice or clawing its way into an asteroid could provide two advantages: shielding from cosmic and gamma rays and the ice that is melted to tunnel into the asteroid could become part of a much larger dark matter detector. Both of these advantages would allow a much larger dark matter detector than could have been brought with the spacecraft from Earth.
