摘要:

MIMAC项目是一个多室探测器,用于暗物质搜索,旨在测量轨道和电离与矩阵的micromegas微型TPC填充氦和CF4。最近的实验结果的第一次测量的氦淬火因子在低能量(1千电子伏反冲),连同第一次模拟的轨道重建。氡杂质的α径迹的重建作为概念的第一个证明。

英文摘要:

The MIMAC project is a multi-chamber detector for Dark Matter search, aiming at measuring both track and ionization with a matrix of micromegas micro-TPC filled with He3 and CF4. Recent experimental results on the first measurements of the Helium quenching factor at low energy (1 keV recoil) are presented, together with the first simulation of the track reconstruction. Recontruction of track of alpha from Radon impurities is shown as a first proof of concept.
