直接暗物质探测器中的电离辐射
Recoiling Ion-Channeling in Direct Dark Matter Detectors
摘要：
在直接探测实验中，WIMP碰撞后反冲核在晶体探测器中的通道效应会产生比预期更大的闪烁或电离信号。我目前估计的通道分数使用分析模型从20世纪60年代起，描述通道和阻塞效应。我们发现分数太小，影响适合潜在的WIMP候选人。我也检查了探测到由于通灵而导致的暗物质信号的每日调制的可能性。
英文摘要：
The channeling of the recoiling nucleus in crystalline detectors after a WIMP collision would produce a larger scintillation or ionization signal in direct detection experiments than otherwise expected. I present estimates of channeling fractions obtained using analytic models developed from the 1960's onwards to describe channeling and blocking effects. We find the fractions to be too small to affect the fits to potential WIMP candidates. I also examine the possibility of detecting a daily modulation of the dark matter signal due to channeling.
