"DRIFT - A Dark Matter Search with a Negative Ion TPC"

9901721Martoff与斯诺登-伊夫特(Snowden-IFFT)(共同发现了被称为负离子漂移室的新探测器的原理)和一些英国科学家合作，提议建造一个定向反冲识别径迹探测器，以搜索弱相互作用的大质量粒子。用该探测器的原型进行的测试表明，该探测器比目前运行的一套基于闪烁和低温探测器的冷物质探测器具有更好的背景抑制能力。他提议在三年内建造一个1000立方米的探测器，并在英国的Bulby矿进行操作。该探测器的灵敏度与当前探测器组的灵敏度相当，但它将具有当前探测器所不具备的导向器感测能力。

9901721MartoffThe PI, Martoff, in collaboration with Snowden-Ifft (co-discovered of the principle of the new detector called negative-ion drift chamber) and a number of British scientists proposes to build a directional recoil identification track detector to search for weakly interacting massive particles. Tests carried out with a prototype version of this detector showed that this detector has better background rejection than the current set of operating cold matter detectors based on scintillation and cryogenic detectors. He proposes to build a 1 cubic meter detector in three years and operate it in the Bulby Mine in UK. The sensitivity of this detector is comparable with those of the current set of detectors but it will have the director sensing capability not present in current detectors.
