Local: Auditório Ministro João Alberto Lins de Barros, no CBPF, à rua Dr. Xavier Sigaud 150, Urca, Rio de Janeiro (RJ)

Dia: 27 de novembro de 2018 (terça-feira)

Horário: 16h

Entrada gratuita, sem necessidade prévia de inscrição. Público externo deve apresentar documento de identificação na portaria.

 

Resumo:

The miniaturized spectrometer for Mössbauer spectroscopy (MIMOS II) was developed for extraterrestrial Solar System exploration and has been included already in the exploration of the planet Mars (Mars-Exploration-Rover missions Spirit and Opportunity; Beagle 2 lander), and the in-situ investigation of the Martian moon Phobos. The instrument is part of the payload of proposed space missions to different Solar System bodies. These include asteroids, comets, Martian moons, the Earth moon, Mars, Venus, and Mercury. Some examples of mission projects will be discussed.  Because of its small size and low power consumption the instrument MIMOS II is portable, which opens a large variety of new terrestrial applications like field experiments, environmental monitoring, prospecting of ores etc., analysis of artifacts, paintings, etc., and many others. Some examples will be presented and discussed.

 

BREVE CV: 

Dr. Klingelhöfer got is diploma degree in physics in 1984 at the University of Darmstadt (Germany), in the field of nuclear solid state physics applying high resolution Fe-57 conversion electron Mössbauer spectroscopy to very thin surface layers, using electrons in the low energy range (some eV; LEEMS) up to keV energies (up to 13.6 keV; DCEMS).

He received his doctoral degree (PhD) in Darmstadt for his unique work on the origin of nuclear magnetic hyperfine fields in iron. As postdoctoral fellow at TU Darmstadt, he designed and developed the miniaturized Mössbauer spectrometer MIMOS II for space application. MIMOS II was the first MB instrument ever used in space, investigating the surface of the planet Mars.

He received the ‘Helmholtz Award for Metrology’ in 2007, and the ‘Eugen Sänger-Medal 2005’, awarded by the Deutsche Gesellschaft für Luft- und Raumfahrt – Lilienthal-Oberth e.V., for the unique contribution on the understanding of the role of water on Mars.

In 2006, he was the first to receive the ‘IBAME award’ in recognition of exceptional contribution to Mössbauer spectroscopy. At present, Dr. Klingelhöfer  is active in 'experimental planetology' at the University Mainz (Germany).
