MIT Reports to the President 1999–2000


FRANCIS BITTER MAGNET LABORATORY

The Francis Bitter Magnet Laboratory (FBML) has continued to make notable advances in several areas of science and engineering involving high magnetic fields. The research program in Magnetic Resonance (nuclear magnetic resonance (NMR), and electron paramagnetic resonance (EPR)) has continued to grow and remains the largest effort at the FBML. The program is funded primarily by the NIH and DOE, and involves ~20 NMR and EPR magnets and spectrometers.

A few of this year’s highlights include the following.

Professor Robert G. Griffin, together with Professor Gerhard Wagner of Harvard University, continue to operate The MIT/Harvard Center for Magnetic Resonance, a collaborative research effort between MIT and Harvard Medical School. The Center is supported by a NIH Research Resource grant that was renewed for five years.

Professor Harald Schwalbe joined the Department of Chemistry in October, 1999. His offices and laboratory space are presently located at the FBML. Professor Schwalbe’s area of research is focussed on solution NMR studies of protein folding and structures of ribonucleic acids.

Professor Cory and his colleagues continue to make rapid advances in the theory, practice and implementation of quantum information processing. In collaboration with Bruker Instruments, Inc., they have helped to develop and taken delivery of the first special-purpose commercial NMR designed for quantum information processing. They are now constructing a second-generation quantum processor that is designed to reach more than 10 qubits.

Dr. Yukikazu Iwasa received funding from NIH to construct a very high field, wide bore 700 MHz NMR system. The system is essentially complete and has successfully passed most test and we anticipate delivery in a few weeks. A unique feature of the magnet is a 500 Gauss sweep coil essential for dynamic nuclear polarization experiments.

Dr. Jagadeesh Moodera has continued to strengthen his research efforts in condensed matter physics through collaboration with various universities and industries, as well as the ONR and NSF. In addition, he has continued his mentoring of graduate students, undergraduate and high school students by providing research opportunities within his lab. Dr. Moodera received the 2000 TDK Research Award for his pioneering studies in spin tunneling.

FACILITIES

During the past year, FBML resources were consolidated into one building. We now boast an upgraded space for 2 750 MHz NMR magnets, as well as space for the wide bore 750 MHz magnet to be built under Dr. Yukikazu Iwasa.

Newly renovated facilities have recently been provided for Professor Cory’s research group, including a wet lab and a computer lab.

Professors Keith Nelson and Andrei Tokmakoff of the Department of Chemistry have left the temporary lab space on the first floor used during completion of their permanent laser lab facility in the Chemistry Department.

Extensive renovation has been complete on the second floor to provide office space for Professor Jacquelyn Yanch, Professor David Cory and their students.

EDUCATION AND PERSONNEL

The Laboratory contributes to undergraduate education by participation in the Undergraduate Research Opportunities Program (UROP) a program that encourages and supports research-based intellectual collaborations of MIT undergraduates with Institute faculty and research staff. In addition, the laboratory has 20 full-time graduate and 8 postdoctoral students performing research.

FUTURE PLANS

Third magnet cell for a wide bore 700 MHz magnet is under renovation and requires completion.

During the past year 900 MHz instruments have been completed, and we have been told that NIH will issue a call for proposals to purchase these instruments early in 2001. We plan to submit such a proposal for a complete system which will be part of the MIT-Harvard CMR. In connection with this proposal will be requesting that NW15 be renovated to accommodate two 900/1000 MHz NMR magnets.

In the longer term we also plan to complete construction of the second floor magnet hall, and instruments currently housed on the fourth and fifth floors will be relocated in order to create a comprehensive "Center for Magnetic Resonance." An alternative plan would be as Professor Schwalbe’s research group grows, the space could house his instrumentation.
