17.11.2014 - PATRICK BÖHM AN DER OHIO STATE UNIVERSITY, COLUMBUS, OHIO, USA
Patrick Böhm visited the non-equlibrium thermodynamics laboratory (NET-Lab) research group at the Department of Mechanical and Aerospace Engineering (MAE) at the Ohio State University (OSU) from August 8th to November 11th 2014. The group is supervised by Prof. Igor Adamovich and Prof. Walter
Lempert. A four wave mixing technique to measure electric fields in hydrogen similar to the one applied in project A3 of FOR1123 was applied. During this stay a new fast ionization wave discharge setup was developed in which electric field measurements were conducted. This measurements had
sub-nanosecond time resolution due to the use of a picosecond pulsed pump-laser. Even polarization sensitive measurements were possible enabling further investigation of the behavior of the wave. The results were presented on the 67th annual Gaseous Electronics Conference and will also be
presented at the AIAA meeting in Kissimmee, Florida in January 2015, and at the DPG Spring Meeting in Bochum, Germany in April 2015.
