Sascha Krause
Gästforskare vid
Chalmers, Rymd-, geo- och miljövetenskap, Onsala rymdobservatorium, GARD teknik
Sascha Krause flyttade till Sverige 2011 för att studera på masterprogrammet Wireless, Photonics and Space Engineering efter att han tagit examen i Elektroteknik 2011 i Magdeburg, Tyskland. Det utmanande ämnet att utveckla THz-mottagartekniker ledde till att han 2013 blev doktorand i enheten Avancerad mottagarutveckling (GARD).Arbetet handlar mestadels om förbättrandet av supraledande material och teknik använd av radiomottagare vid astronomiska obsvervationer i THz-frekvensradien. Dessa frekvensband är särskilt värdefulla när man undersöker processer relaterade till kall massa, som t.ex. vid stjärnfödslar.Sascha har även erfarenhet i nanofabrikationslaboratrium, speciellt inom tunnfilmavsättningstekniker och mikrofabrikation, sedan 2012.
