用Halbach八极阵列比较两种磁超冷中子俘获方案
A comparison of two magnetic ultra-cold neutron trapping concepts using a Halbach-octupole array
摘要：
本文介绍了一种新型的超冷中子磁阱，它由一个长1.2 m、内径为47 mm的Halbach八极永磁体阵列和一组超导端部线圈及偏置场螺线管组成。在一个垂直的，磁引力和水平设置的陷阱的使用进行了比较的有效体积和控制的关键系统的影响，需要在高精度的中子寿命测量的能力。
英文摘要：
This paper describes a new magnetic trap for ultra-cold neutrons (UCNs) made from a 1.2 m long Halbach-octupole array of permanent magnets with an inner bore radius of 47 mm combined with an assembly of superconducting end coils and bias field solenoid. The use of the trap in a vertical, magneto-gravitational and a horizontal setup are compared in terms of the effective volume and ability to control key systematic effects that need to be addressed in high precision neutron lifetime measurements.
