MEETINGS AT NIST
Sigma Xi Seminar

THE ELECTRON BEAM ION TRAP: TAILORING ATOMIC CHARGE FOR SCIENCE AND TECHNOLOGY

John Gillaspy
Atomic Physics Division, NIST, Gaithersburg. MD


Monday, March 30, 1998, 10:30AM, Lecture Rm. B, Administration Bldg.

This talk will provide an introduction to the electron beam ion trap (EBIT), a small device which is capable of producing ions with unusually high charge states. The EBIT laboratory at NIST is one of the few places in the world with the capability to produce ions with charge states as high at 70+. Such highly charged ions can be confined in an electromagnetic bottle for study, or formed into directed beams which can be used to bombard surfaces. In either case, the exotic nature of the high charge state manifests itself in unusual charge-dependent processes which are of fundamental interest. These processes are being studied, with a particular emphasis on assessing potential practical applications which may emerge in the future. Various spectroscopic techniques are used to probe the ions themselves, and scanning probe microscopy is used to study bombarded surfaces with atomic scale resolution. Both the EBIT device itself and the various studies underway with it will be reviewed.

ITL Seminar Series

VRML: CURRENT APPLICATIONS AND FUTURE OPPORTUNITIES

Tony Parisi
CEO, Intervista Software.
Linda Branagan, former Product Manager for WorldView, Intervista Software

Tuesday, March 31, 1998, 10:30AM, Lecture Rm. B, Administration Bldg.

The Virtual Reality Modeling Language (VRML) is a standards-based mechanism for displaying interactive, three-dimensional worlds. Although VRML is a relatively young technology, it is enjoying widespread acceptance and a great deal of use. This talk will discuss a brief history of VRML, including its rapid standardization effort. It will also describe some of the most interesting real-world applications of VRML, the current software product landscape, and future directions for VRML that have already been identified.

Tony Parisi is the co-founder and CEO of Intervista Software and the co-author of the original VRML specification along with Mr. Mark Pesce.

Linda Branagan is the former Product Manager for WorldView, Intervista's VRML viewer. She is soon to be the Director of Engineering at Construct Internet Design, one of the first Internet content companies to develop and deliver VRML commercially.

IEC98 - PLANNING STATUS REPORT

Stanley Warshaw
Senior Policy Advisor for Standards and Technology.


Tuesday, March 31, 1998, 3:00PM, Lecture Rm. B, Administration Bldg.

The 62nd General Meeting of the International Electrotechnical Commission will take place in Houston Texas, October 12-22, 1998. This will be the largest international standards meeting to be hosted in the United States in over 25 years. It will be the first one to introduce the extensive use of electronic document preparation and distribution capabilities. Many private and public entities in the United States have contributed resources to support this international event.

Dr. Stanley I. Warshaw serves as NIST's representative on the Planning Committee for IEC98; he will describe the plans and arrangements for this meeting.

NIST Colloquium Series

BRIDGES BEGET BRIDGES: THE CASE OF NEW YORK CITY

Henry Petroski
Chairman, Civil and Environmental Engineering Department, Duke University.


Friday, April 3, 1998, 10:30AM, - Friday, April 3, 1998 Green Auditorium, Administration Bldg.

This illustrated talk will outline the evolution of bridges in New York City in the period 1880-1920 when so many of its great bridges were designed and built. The completion of the Brooklyn Bridge in 1883 will be discussed as the impetus for the other great suspension bridges connecting Manhattan to Long Island and New Jersey. The debate over whether a bridge over the Hudson River was to be a suspension or cantilever structure will be presented in the context of the design and behavior of contemporary bridges elsewhere in the world. Similar dynamics continue to influence bridge building today, and the same thing that drives the evolution of bridges also drives technological development generally.

CIRMS' MEASUREMENTS AND STANDARDS FOR INTRAVASCULAR BRACHYTHERAPY WORKSHOP

Multiple Speakers
NIST, Industry, National Laboratories, Medical Centers.


Monday, April 6, 1998, 8:30AM, - Tuesday, April 7, 1998 Rm. C301, Radiation Physics Bldg..

The Medical Applications Subcommittee of the Council on Ionizing Radiation Measurements and Standards (CIRMS) is holding a workshop to address the measurements and standards issues associated with the use of radioactive sources to prevent restenosis following balloon angioplasty procedures. The purpose of the workshop is to facilitate a discussion in the measurement community of the standards and measurement needs relating to radioactive seeds, wires, stents, fluid-filled catheters, and x-ray sources used in the emerging field of intravascular therapy.

Nanokelvin Science Seminar

VORTEX STABILITY AND CRITICAL ANGULAR VELOCITIES IN DILUTE TRAPPED BOSE-EINSTEIN CONDENSATES

Alexander S Fetter
Stanford University. Stanford, CA


Tuesday, April 7, 1998, 3:00PM, - Tuesday, April 7, 1998 Rm. B105, Radiation Physics Building.

Recent experimental demonstrations of Bose-Einstein condensation in cold dilute trapped alkali gases have created an exciting new field. Together, the harmonic trap and interparticle interactions yield new and different physics from the more familiar uniform dilute Bose gas. The condensate remains irrotational for slow rotation speeds, but a vortex eventually appears and can remain metastable even for somewhat reduced rotation speeds. Above a higher critical angular velocity, however, the system becomes dissipative, reverting to the normal (noncondensed state).

SPECTROSCOPY OF SEMICONDUCTOR QUANTUM DOTS BY NEAR-FIELD OPTICAL MICROSCOPY AND DEVELOPMENT OF AN APERTURED METALLIC PROBE

Takuya Matsumoto
Tokyo Institute of Technology. Japan


Wednesday, April 8, 1998, 10:30AM, Room B165, Physics Building.

Photoluminescence spectra of single InGaAs quantum dots, and spatial variations in the PL spectrum were measured by a low temperature near-field optical microscope. The spatial resolution was 100 nm. A novel probe with a metallic protrusion surrounded by an aperture has been developed to increase the resolution and the light excitation and collection efficiency further. A probe having a nanometric metallic particle at its apex has also been developed to increase the optical near-field intensity by localized plasmon excitation.

DESIGN OF EXPERIMENTS

Eric Lagergren
Statistical Engineering Division, NIST, Gaithersburg, MD.


Thursday, April 9, 1998, 9:00AM, Lecture Room B, Administration Building.

(Later lectures on April 16, 23, 30, 9:00 a.m.-12:00 noon, Lecture Rooms A, B, and C, respectively.)

This 12 hour workshop covers the fundamental principles and techniques of efficient experiment design--a rigorous strategy for conducting an experimental investigation. A "good" design yields unambiguous scientific and engineering conclusions with a minimal amount of experimental effort. The workshop covers specific designs that have proven best for screening out the most important parameters from a large number of potential parameters and for converging to an optimal operating condition starting from a "best guess." Registration is limited. The registration fee of $125 includes the textbook "Statistics for Experimenters," by Box, Hunter and Hunter. To register, submit a Request for Training Memo to Pat O'Connor, Room A123, Administration Building, patricia.oconnor@nist.gov, by April 3, 1998.

ZOOMABLE USER INTERFACES (ZUIS)

Dr. Benjamin B. Bederson
Assistant Professor of Computer Science, The University of Maryland,. College Park, MD


Monday, May 4, 1998, 11:00AM, Room B142, Technology Building.

Pad++ is a zoomable user interface designed for interactive graphical data creation and browsing. It takes the spatial metaphor standard from the computer window desktop interface one step further by incorporating the concept of scale. Pad++ is a two-dimensional surface that acts like a sketchpad, but is orders of magnitude larger in extent and resolution, allowing information to be created not only at any location, but at any size as well. This talk will describe and demonstrate how we are using zooming for different kinds of interactions and visualizations.
