Neutron detection finds wide use in various areas, thus the improvement of the relevant instruments and methods has been focused on for a long time. For the purpose of detecting possible neutrons, in the present paper, we theoretically put forward a carbon nanotube (CNT) sensor based on a single nitrogen-vacancy center coupled to a current-carrying CNT to detect neutrons. With two lasers applied, the accreted mass landing on the nanotube may cause a frequency shift in the probe absorption spectrum. Once the frequency shift is measured, the added mass will be determined. Through the use of this sensor, owing to the small effective mass and high quality factor of the CNT, an ultrahigh mass resolution could be achieved. Due to its ultrahigh resolution, the sensor can be used to detect neutrons. Furthermore, we provide a brand new optical approach for neutron detection.

用超高分辨率碳传感器光学检测亚原子颗粒

中子检测在各个领域都有广泛的用途,因此长期以来一直致力于改进相关仪器和方法。为了检测可能的中子,在本文中,我们从理论上提出了一种基于单个氮空位中心并与载流CNT耦合以检测中子的碳纳米管(CNT)传感器。使用两个激光时,堆积在纳米管上的积聚质量可能会导致探针吸收光谱发生频移。一旦测量了频移,就将确定增加的质量。通过使用此传感器,由于CNT的有效质量小和品质因数高,因此可以实现超高质量分辨率。由于具有超高分辨率,该传感器可用于检测中子。此外,
