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.

The presentation files are archived here. EMAL Practical Workshop Number 1 in an Occasional Series

EMAL and JEOL USA Inc. are pleased to present:

Optimal Use of the JEOL 2010F for Advanced Transmission Electron Microscopy

Dr. Mike Kersker
Vice President
&
Dr. Masahiro Kawasaki
Applications Specialist

JEOL USA Incorporated, 11 Dearborn Road
Peabody, MA 01960

Exact times to be determined
Probably morning lectures and afternoon laboratories
Tuesday, Wednesday and Thursday, June 27th, 28th and 29th, 2006

Lectures in Room 2246, Space Research Building, University of Michigan, Ann Arbor, MI 48109-2143
