Note: the notice below is the original posting for the workshop. Due to the fact that Mike Kersker and Masa Kawasaki were unable to travel to Michigan that week, two other lecturers were added to the schedule. Robert Klie from Brookhaven National Laboratory and Alan Nicholls from the University of Illinois at Chicago came to Michigan and presented lectures and Mike Kersker presented his lecture via the internet.
EMAL and JEOL USA Inc. are pleased to present:
Dr. Mike Kersker
JEOL USA Incorporated, 11 Dearborn Road
Exact times to be determined
