It has been another exciting year in the Macdonald Laboratory.
We have just completed and submitted to DOE our three year progress
report for the period FY92-FY94, and our three year proposal for
In November 1994 we anticipate that an outside review panel of
the Department of Energy will be here to review our progress and to
discuss our proposed research. The result of this review sets the
standard for our funding for the next three years. Our requested
budget level for FY95 funding, which begins February 15, 1995 for us,
is approximately 1.9M$.
The JRM staffing level is nearly the same as last year. We
have 13 faculty, 2 visiting faculty, 4 research associates, 7 staff
members, 14 graduate students, and 6 undergraduate students.
Here are some of the exciting things occurring in the laboratory:
- Prof. Frank Melchert, from the University of Giessen, is
here on a one-year Humboldt Fellowship. He is working on the new
ion-ion collision facility with Prof. John Giese.
- Prof. Eduardo Montenegro, from Pontificia Universidade
Catolica Do Rio De Janeiro, Brazil, is here on a one-year sabbatical
leave. He is working with Profs. Itzik Ben-Itzhak, Lew Cocke and Pat
Richard, on several new LINAC experiments and contributing greatly
with theoretical analyses.
- One of the very successful efforts this year is the
increased involvement of outside users.
- Prof. Steve Lundeen's group from Colorado State University,
Fort Collins, spent the summer here setting up his powerful laser
produced Rb Rydberg target for experiments on CRYEBIS. The
experiments are being performed in collaboration with Prof. Brett
DePaola's group. Total electron capture cross section measurements
from high Rydberg states by highly charged ions have been successfully
completed. The second stage of these experiments is in progress.
- A collaboration with Profs. Eugene Rudd and Tim Gay from the
University of Nebraska has been initiated. An electron spectrometer
system equipped with a Slevin type atomic hydrogen target developed at
the University of Nebraska has been put into operation on the JRM Lab
LINAC. The apparatus will be used to measure for the first time the
global production of electrons by pure ionization from high Z bare
ions on atomic hydrogen. This project addresses the Z-scaling of the
most fundamental three-body atomic collision system. The work is
being done in collaboration with Profs. Lew Cocke, Siegbert Hagmann,
and Pat Richard. Dr. Robert Moshammer, who is visiting from GSI,
Darmstadt, is the person devoting full time to this experiment.
- The third new collaboration initiated is with Profs. Emanuel
Kamber and John Tanis from the University of Western Michigan.
Emanuel spent the summer here working on electron production
experiments at the EBIS as well as planning for future experiments.
He is collaborating with Prof. Lew Cocke and Dr. Martin Stockli.
- We hired Paul Gibson as an assistant scientist to assist
Martin in the operation, maintenance and use of the EBIS. This has
allowed Martin some much needed breathing space and allowed him to
reduce his long list of "things to be done." Paul worked for the
Macdonald Lab on the EBIS project at the beginning of the laboratory
upgrade project in 1985-88 as an undergraduate assistant. We are very
pleased to get him back.
- Last year I mentioned our effort to get funds from the
Department of Energy ARIM fund. We were successful and received
$621,000 for improvements to the LINAC, CRYEBIS, and associated
equipment. We have a request for FY96 ARIM funds which I understand
is approved by DOE, contingent on DOE's congressional budget approval.
- Vickie Frohne received her Ph.D. degree in 1994 under the
direction of Prof. Lew Cocke. She is presently an Assistant
Professor at Western Illinois University.
- For the third consecutive summer, the JRM Lab hosted eight
undergraduate students in the NSF REU summer trainee program.
Prof. Larry Weaver was in charge of the program, doing an outstanding
job lecturing these students and quizzing them during oral reports on
their research projects.
- For the third consecutive summer, we also hosted graduate
students from the University of Dresden, Germany. This summer we had
four students who spent 10 weeks of research training in the JRM Lab.
