SMP 12/6/03 | Why Make Holes in Superconductors? | Speaker: Sa-Lin Cheng Bernstein

Saturday, December 6, 2003
12:00 AM
170 & 182 Dennison Building

Speaker: Dr. Sa-Lin Cheng Bernstein (U-M Physics)

Type II superconductors differ from Type I superconductors because of the appearance of interior magnetic flux lines. The movement of flux lines within a superconductor causes dissipation of internal energy. In order to "pin" flux lines in place, "flux pinning centers" are introduced. Dr. Sa-Lin Cheng Bernstein will discuss various techniques which have been used to produce artificial pinning centers in the form of microscopic holes to better understand flux pinning in superconductors. Research has shown that the presence of a regular pattern of holes enhances the effects of pinning.

Detailed Information
All talks are free and refreshments will be served. Visitor parking for the seminars (Central Campus) is across the street from the Dennison Building in the U-M Church Street structure. There is a $2.00 parking charge implemented by U-M Parking Services.
