New RBS System Delivers Data in 15 Minutes A new generation Rutherford backscattering surface analyzer, recently introduced by General Ionex Corporation, performs routine NDT surface and depth analysis of any element from lithium through uranium within 0.01-1% atomic detection limits. The system provides spectral answers in 15 minutes. Model 4175 features a fixed beam energy of 2MeV He2*, beam current adjustable to at least 50 nanoamperes, beam spot sizes of 2mm x 2mm, sample target holder with light beam alignment and X-Y positioning adjustment of ±5mm, push-button microprocessor control of all instrument functions, and a user friendly software package for data acquisition and spectral analysis. For further information, contact General Ionex Corporation, 19 Graf Road, Newburyport, MA 01950; telephone (617) 462-7147.

Robert Sundahl Heads Signal UOP Research Center's Materials Science Department Robert C. Sundahl, Jr. has joined Signal UOP Research Center, Des Plaines, IL, as head of its expanded Materials Science Department. Sundahl was previously with AT&T Bell Laboratories where his work centered on areas affecting the telecommunications and electronics industries, including lightwave communications, hybrid and integrated circuits, piezoelectric crystal resonators and filters, and electronic ceramics. As head of the UOP Materials Science Department, Sundahl will spearhead new basic materials programs in such areas as ceramics, metallurgy, polymers, and composites. Signal UOP is an MRS Corporate Affiliate, and Sundahl serves as corporate representative to the Society.

Solid State Technology Cites MRS as Important Force in Electronic Materials Research The 1984 MRS Fall Meeting, held last November in Boston, was one of three recent meetings cited by Solid Slate Technology as

significantly contributing to the quickening pace of interdisciplinary knowledge to the solid state industry. In the March 1985 issue, Editor Sidney Marshall said that MRS meetings "have become important focal points for the presentation of research results in general, and on electronic materials in particular." The technical sessions from the Fall Meeting, he emphasized, were "timely and of great interest to many solid state materials specialists."

Marshall called the Society a leading proponent of materials science and noted that it continues to expand its coverage of electronic materials topics.
