Noriko Kita Cosmochemistry Research

Primitive meteorites recorded the early evolution of the solar system. We use SIMS to obtain high precision isotope analyses of pristine meteorite samples, such as Ca, Al-rich inclusions and chondrules in order to address the timing of their formation and the condition of proto-planetary disk in which they formed. We are also interested in precious particles collected from asteroidsand comets by space missions, such as NASA Stardust Mission.

WiscSIMS Laboratory for in-Situ Isotope Analysis of Extraterrestrial Sample (NASA Planetary Science Enabling Facilities Program: 2025-2029)

Wisconsin Secondary Ion Mass Spectrometer Laboratory (WiscSIMS) is equipped with CAMECA IMS 1280, a large magnetic-sector SIMS, and specializes in high precision in-situ stable isotope analyses of minerals at 1-10 μm lateral resolutions. WiscSIMS laboratory has been funded by NSF Earth Science Instrumentation and Facilities Program as a National Facility for Stable Isotope Geochemistry and devotes 50% of beam-time assisting NSF-funded geoscience projects. With support from NASA Planetary Science Enable Facilities Program (PSEF), WiscSIMS will assist projects that are funded by Programs of the NASA Planetary Science Division (PSD) and broader extraterrestrial sample analysis community, in a similar way to the NSF Facility Program. Users are expected to acquire high quality SIMS isotope data with very little former experiences. The performance of WiscSIMS IMS 1280 has been significantly improved by multiple commercial upgrades and in-house modifications, so that the instrument is capable of obtaining the world’s highest precision and accuracy data for oxygen 3-isotope analyses and Al-Mg chronology of extraterrestrial samples, such as Ca, Al-rich inclusions and chondrules in primitive meteorites, micrometeorites, interplanetary dust particles, comet Wild 2, and asteroid return samples. The results of SIMS analyses are crucial for understanding the sources and evolution of primitive solids in the early Solar System. PI Kita and her team will support 3-4 SIMS sessions (up to one week per session) each year for external extraterrestrial sample analyses and the projects that are funded by NASA PSD programs receive the high priority in the time allocation. We will evaluate analysis plans, inspect samples by surface profilometer, set up and run calibration standard, assist users to analyze samples, and finalize data. The instrument fee will be the same as for NSF projects, $1,800 per day (12 hours), which will not be applied to set up time and time for analyzing calibration standards.
