标题： Superheated Droplet Detectors as CDM Detectors: The SIMPLE Experiment

摘要： 超热液滴探测器（SDDs）在中子个人剂量测定中正变得越来越普遍。 它们对最小电离辐射的完全不敏感性（而对能量约为几keV的核反冲有响应），加上其低成本、易于生产以及在室温和1 atm条件下操作，使它们成为冷暗物质（CDM）搜索的理想选择。 由于氟含量高，SDDs最适合探索自旋依赖的中性微子耦合。 介绍了SIMPLE（用于大质量粒子实验的超热仪器）的现状。 在考虑实际背景的情况下，我们预计在获取约1 kg-y的数据后，目前的冷暗物质灵敏度将提高2-3个数量级。 显示英文摘要

摘要： Superheated Droplet Detectors (SDDs) are becoming commonplace in neutron personnel dosimetry. Their total insensitivity to minimum ionizing radiation (while responsive to nuclear recoils of energies ~ few keV), together with their low cost, ease of production, and operation at room temperature and 1 atm makes them ideal for Cold Dark Matter (CDM) searches. SDD's are optimal for the exploration of the spin-dependent neutralino coupling due to their high fluorine content. The status of SIMPLE (Superheated Instrument for Massive ParticLe Experiments) is presented. Under realistic background considerations, we expect an improvement in the present Cold Dark Matter sensitivity of 2-3 orders of magnitude after ~1 kg-y of data acquisition.
