现在暗电子倍增器可以感应到守护进程的运动方向
Now the Dark Electron Multiplier does sense direction of the daemon motion
摘要:
我们用一个平面水平闪烁器在北半球高纬度(~ 60 °)的初级近地守护进程通量中检测9月最大值受到纯粹几何因素的困扰;事实上,由于地球的旋转轴倾斜,守护进程在近地外极近圆日心轨道(NEACHO)中追赶地球,沿着接近水平的路径撞击地球。然而,仅应用两个相反取向的、专门设计的TEU-167 d型“暗电子倍增器”,(只有直径为125 mm的前盘在内部涂有厚的~0.5 um Al层,这允许这种倍增器主要检测从底部到盘在它们内部飞行的守护程序)使我们有可能在一个实验中检测到,在>3 sigma的置信水平上,从近地天体观测卫星捕获到的进入地心地球表面穿越轨道的守护进程通量,以及记录这些物体在约1个月的特征时间内由于它们在穿越地球时减速而导致的速度从约10公里/秒下降到约7公里/秒。
英文摘要:
Detection of the September maximum in the primary near-Earth daemon flux at high (~60o) Northern latitudes by our set-up with a plane horizontal scintillator is plagued by purely geometric factors; indeed, because of the Earth's rotation axis being tilted, the daemons catching up with the Earth in outer Near-Earth, Almost Circular Heliocentric Orbits (NEACHOs) strike the Earth along close-to-horizontal paths. Nevertheless, application of only two oppositely oriented, specially designed "dark electron multipliers" of the type TEU-167d (only their dia.125-mm front disc is coated on the inside by a thick, ~0.5 um Al layer, which permits such multipliers to detect primarily daemons flying inside them from the base to the disc) has made it possible for us to detect in one experiment, at a confidence level of >3 sigma, a flux of daemons captured from NEACHOs into Geocentric Earth-Surface-Crossing Orbits, as well as to record a decrease in the velocity of these objects from ~10 to ~7 km/s in a characteristic time of ~1 month resulting from their being slowed down in transits through the Earth's body.
