1. ELECTRON INTERFEROMETERS WITH ATOMIC PRECISION
Artificial solids with tailored electronic properties have been a
long-term dream. With the skills in manipulating surfaces acquired over the last two
decades, scientists are getting closer to this goal. Jens Paggel, Tom Miller, and Tai
Chiang (U. Illinois Urbana) are pushing the frontier all the way to the atomic limit. They
fabricate miniature electron interferometers consisting of an atomically-smooth silver
film on a single crystal iron whisker. Synchrotron radiation from the SRC is focused onto
the tiny, but perfect whisker and reveals how the electron waves are modified in these
small structures. The fast-oscillating wave of a free electron becomes modulated by an
envelope wave function with longer wavelength. Instead of a continuum, sharp peaks appear
in the electron spectrum. For details, see J.J. Paggel, T. Miller, T.-C. Chiang, Science
283, 1709 (1999). For a perspective, see F.J. Himpsel, Science 283, 1655 (1999).
2. CANADIAN SYNCHROTRON LIGHT SOURCE FUNDED
The Canada Foundation for Innovation (CFI) has approved a C$ 56.4 M
contribution to build the Canadian Light Source (CLS) in Saskatoon. The decision gives the
green light to the C$ 173.5 million national facility, the largest scientific project ever
to be built in Canada. The state-of-the-art facility is expected to begin operation in
2003 and be fully operational in 2008. Congratulations to our Canadian colleagues, who
have contributed significantly to the SRC and currently represent 16 % of the SRC users.
3. 1999 SRC WORKSHOP ON LOW-DIMENSIONAL SYSTEMS
After a poll among the users it was decided to have Low-Dimensional
Systems as the main theme of the SRC Workshop on Saturday Oct. 9, 1999. Let Franz Himpsel
(email@example.com) know about suggestions for specific speakers and topics.
In addition to the technical part, several tutorials are planned, both on the topic of the
workshop and on synchrotron radiation research as a whole.
4. HONORS FOR SRC RESEARCHERS
Hong Ding (U. Illinois Chicago, now Boston College) won a Sloan
Research Fellowship for his work on high temperature superconductors and correlated
Gelsomina "pupa" De Stasio accepted a Full Professorship in
the Physics Department of the UW-Madison.
... and some awards in 1998 that did not appear in this column yet:
Franco Cerrina (UW-Madison and CXrL) won the Aristotle Award of the
Semiconductor Research Corporation (the other SRC) which acknowledges outstanding teaching
in its broadest sense.
Tom Kuech (UW-Madison) became Fellow of the American Physical
Al Arko, John Joyce, and Kevin Graham (LANL), were named recipients
of the Los Alamos Distinguished Performance Award.
Congratulations to everyone!
