一个精密的质谱仪，灵敏到足以检测到 单个捕获离子的离子回旋共振频率， 将用于测量He/H质量比，提供上限 电子中微子的巢质量极限。 应当 可以确定伽马射线的质量， 普朗克常数和Avagardro数的乘积，也 独立地确定另一个中的精细结构常数， 实验捕获离子技术将用于研究碰撞 原子之间的能量低于温度的百万分之一 大多数热原子碰撞过程，提供 理解碰撞过程中的自发衰变， 在碰撞期间使用辐射来切换电势曲线

A precision mass spectrometer, sensitive enough to detect the ion cyclotron resonance frequency of a single trapped ion, will be used to measure the He/H mass ratio, providing an upper limit on the nest mass of the electron neutrino. It should be possible to determine the mass of a gamma ray and thence the product of Planck's constant and Avagardro's number, also independently determining the fine structure constant in another experiment trapped ion technology will be used to study collision between atoms at energies below one millionth of the temperature of most thermal atomic collision processes, providing understanding of spontaneous decay during the collisions and the use of radiation to switch potential curves during collision
