摘要:

时间投影法是追踪低能释放粒子的理想方法。可以通过中等数量的通道读出大体积,提供敏感体积内的带电轨道的完整3D重建。它不仅允许测量总释放能量,而且还允许测量沿着轨道的能量释放密度,这对于粒子识别和解决轨道的首尾模糊性非常有用。此外,气体是研究暗物质相互作用的一个非常有趣的目标。在气体中,核反冲力可以传播足够长的距离,产生足够长的轨迹,以便获得和重建。

英文摘要:

The Time Projection method is an ideal candidate to track low energy release particles. Large volumes can be readout by means of a moderate number of channels providing a complete 3D reconstruction of the charged tracks within the sensitive volume. It allows the measurement not only of the total released energy but also of the energy release density along the tracks that can be very useful for particle identification and to solve the head-tail ambiguity of the tracks. Moreover, gas represents a very interesting target to study Dark Matter interactions. In gas, nuclear recoils can travel enough to give rise to tracks long enough to be acquired and reconstructed.
