本文介绍了一个用于测量氖同位素β衰变反冲子核能量分布的探测系统的设计、模拟和测试。该分布对弱扇区中的几种新物理效应敏感。我们的“衰变显微镜”依赖于对高能反冲离子的速度分布进行成像,这些离子与衰变中被震落的电子重合。我们证明通过蒙特-卡罗模拟,核显微镜增加的统计灵敏度的运动学测量的潜在的能量分布,并限制了主要的系统偏差所造成的陷阱位置的差异沿着检测轴。
We review the design, simulation, and tests, of a detection system for measuring the energy distribution of daughter nuclei recoiling from the beta-decay of laser trapped neon isotopes. This distribution is sensitive to several new physics effects in the weak sector. Our `decay microscope' relies on imaging the velocity distribution of high energy recoil ions in coincidence with electrons shaken-off in the decay. We demonstrate by way of Monte-Carlo simulation, that the nuclear microscope increases the statistical sensitivity of kinematic measurements to the underlying energy distribution, and limits the main systematic bias caused by discrepancy in the trap position along the detection axis.
