ZEPLIN III暗物质探测器即将准备好在博尔比矿的地下进行调试。这个两相氙系统利用液体中产生的闪烁和电离信号来区分类伽马相互作用和弱相互作用大质量粒子（wimp）从Xe原子散射产生的核反冲。这种对粒子种类的敏感性，加上其组件的低放射性，将提高我们对wimp特征的灵敏度，在部署后的第一阶段，wimp -核子截面低于10/sup -7/ pb，在运行的头几个月后，计划的升级将大大提高灵敏度。
The ZEPLIN III dark matter detector is nearly ready for commissioning underground at the Boulby mine. This two-phase xenon system exploits both scintillation and ionisation signals produced in the liquid in order to discriminate between gamma-like interactions and the nuclear recoils expected from the scattering of weakly interacting massive particles (WIMPs) off Xe atoms. This sensitivity to particle species, together with the low radioactivity of its components, will enhance our sensitivity to WlMP signatures down to a WIMP-nucleon cross-section lower than 10/sup -7/ pb in the first stage after deployment, improving significantly with planned upgrades to be introduced after the first few months of operation.
