用于KATRIN的宽带FT-ICR Penning TRap系统
A broad-Band FT-ICR Penning TRap System for KATRIN
摘要：
卡尔斯鲁厄氚中微子实验KATRIN旨在将电子反中微子的质量上限提高到约0.2 eV（90% c.l.）。通过研究氚气体分子的β衰变该实验目前正在建设中，将于2012年开始第一次数据采集。KATRIN实验中系统不确定性的一个来源是当氚衰变和衰变产物与残余氚分子相互作用时形成的离子簇。这是必不可少的，以监测这些集群的丰度，因为它们有不同的最终状态的能量比氚离子。为此目的，在海德堡的马克斯-普朗克核物理研究所建造并测试了一个圆柱形潘宁阱的原型，该原型将安装在KATRIN束线上。该系统采用傅里叶变换离子回旋共振技术，以测量不同的存储离子种类的丰度。
英文摘要：
The KArlsruhe TRItium Neutrino experiment KATRIN aims at improving the upper limit of the mass of the electron antineutrino to about 0.2 eV (90% c.l.) by investigating the beta-decay of tritium gas molecules. The experiment is currently under construction to start first data taking in 2012. One source of systematic uncertainties in the KATRIN experiment is the formation of ion clusters when tritium decays and decay products interact with residual tritium molecules. It is essential to monitor the abundances of these clusters since they have different final state energies than tritium ions. For this purpose, a prototype of a cylindrical Penning trap has been constructed and tested at the Max-Planck-Institute for Nuclear Physics in Heidelberg, which will be installed in the KATRIN beam line. This system employs the technique of Fourier-Transform Ion-Cyclotron-Resonance in order to measure the abundances of the different stored ion species.
