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.

9901721 Martoff PI Martoff与Snowden-Ifft（共同发现了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，提出建立一个定向反冲识别径迹探测器，以寻找弱相互作用的大质量粒子。 对这一探测器原型进行的测试表明，这一探测器比目前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。 他建议在三年内建造一个1立方米的探测器，并在英国的布尔比矿运行。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中不存在的指向矢感测能力。
