守护程序:在Pulkovo、Gran Sasso和Soudan的检测
Daemons: Detection at Pulkovo, Gran Sasso, and Soudan
摘要:
在2011年3月最大值的一周内,两个相对安装的方向敏感TEU-167 d暗电子倍增器(DEM)记录了来自近地近圆形日心轨道(NEACHO)的守护进程流量。从上面测得的通量为f \approx(8 \pm 3)\times 10^-7 cm^-2 s^-1,而从下面测得的通量要小两倍。这种差异可能是由于标准集装箱本身的具体设计特点,以及物体从上方或下方沿其而来的轨迹的斜率不同。它表明,守护进程的范例,使DAMA和CoGeNT实验的定量解释,没有额外的假设。这两个实验都记录到了一个f ~ 10^-6 cm^-2 s^-1的守护星通量,该通量来自强拉长的穿越地球的日心轨道(SEECHO),它是NEACHO的前身。对DAMA/LIBRA数据的处理给出了建议,这些建议明确地表明,在大约一半的情况下(当探测器中发生双事件时,在单次命中标准下的处理中被拒绝),所记录的信号是由单个SEECHO物体沿着~1 m的路径连续激发的,即,这不是懦夫指出适当地考虑级联事件和离子对相互作用,将减弱阻塞效应对被敲出的碘离子在NaI(Tl)晶体中沟道的不利影响。这种影响将变得不那么灾难性,因为它遵循简化的半分析模型的过程:人们可能会期望高达约10%的初级反冲碘离子的能量将被转换为闪烁光。
英文摘要:
During a week of the March maximum in 2011, two oppositely installed direction-sensitive TEU-167d Dark Electron Multipliers (DEMs) recorded a flux of daemons from the near-Earth almost circular heliocentric orbits (NEACHOs). The flux measured from above is f \approx (8\pm3)\times10^-7 cm^-2 s^-1, and that from below is twice smaller. The difference may be due both to specific design features of the TEUs themselves, and to dissimilarities in the slope of trajectories along which objects are coming from above or from below. It is shown that the daemon paradigm enables a quantitative interpretation of DAMA and CoGeNT experiments with no additional hypotheses. Both the experiments record a daemon flux of f ~ 10^-6 cm^-2 s^-1 from strongly elongated Earth-crossing heliocentric orbits (SEECHOs), predecessors of NEACHOs. Recommendations are given for processing of DAMA/LIBRA data, which unambiguously suggest that, in approximately half of cases (when there occur double events in the detector, rejected in processing under a single-hit criterion), the signals being recorded are successively excited by a single SEECHO object along a path of ~1 m, i.e., this is not a WIMP. It is noted that due regard to cascade events and pair interaction of ions will weaken the adverse influence exerted by the blocking effect on the channeling of iodine ions knocked out in NaI(Tl) crystal. This influence will become not so catastrophic as it follows from simplified semi-analytical models of the process: one might expect the energy of up to ~10% of primary recoil iodine ions will be converted to the scintillation light.
