Research Abstract

In space science, mass spectrometry plays a key role in the analysis of material from planetary and cometary surfaces. Mass spectrometry is able to provide information on 1) the isotope ratios of the elements and 2) the possibility of the existence of organic compounds. In the COSAC project of the ROSETTA mission, to be launched in 2003, a mass spectrometer will be loaded on the lander RoLand in order to analyze the material on the surface of comet 46P/Wirtanen.
We have designed and constructed a new type of multi-turn time of flight mass spectrometer as a laboratory model of this COSAC project. The newly constructed miniature TOF/MS comprises of four electric sectors and eight electric quadrupole lenses. Since this instrument employs the multi-turn ion-optical geometry, the flight time is proportional to the number of turns. Therefore, it can be expected that the mass resolution is also proportional to the number of turns. Some test experiments were carried out using air and Xe as test samples. It have been demonstrated by experiment that the mass resolution can increase according to the number of cycles and the ion transmission through the system is more than 90% after one cycle. The mass resolution was 15000 (m/z=28, FWHM) after 100 cycles.
