Abstract

In May 2014, the Rosetta spacecraft is scheduled to rendezvous with the comet Churyumov-Gerasimenko ('67P'). One of the instruments on board the 'Lander' which will descend on to the surface of the comet is a miniaturised GC/MS system that incorporates an ion trap mass spectrometer, specially developed for isotope ratio analysis. This article describes the development and optimisation of the ion trap for this unique application, and presents a summary of the range of pre-programmed experiments that will contribute to the characterisation of the solid and volatile cometary materials.

摘要

2014年5月，罗塞塔号航天器计划与丘留莫夫－格拉西缅科彗星（“67P”）会合。将在彗星表面着陆的“登陆器”所搭载的仪器之一是一个小型气相色谱/质谱联用系统，该系统包含一个专门为同位素比分析而开发的离子阱质谱仪。本文描述了用于这一独特应用的离子阱的开发和优化，并概述了一系列有助于对彗星固态和挥发性物质进行表征的预编程实验。
