Who's Who'in' Technology Today, Physics and Related Disciplines International Who's Who in Energy and Nuclear Sciences Who's Whc in Engineering Who's Who in America Other important Information One .of Professor Wehring's thesis students, G. Dilorio, won the 1977 Mark Mills Award given by the American Nuclear Society for outstanding graduate research in nuclear science and engineering. In nationwide competition, Dr.

Dilorio's paper, "HIAWATHA: A Fission-Fragment Recoil Mass Spectrometer," was judged best original technical paper submitted for the award.

Professor Wehring's fission research is listed and described in the two report series " Progress in Fission Product Nuclear Data" which is published by the Nuclear Data Section of the International Atomic Energy Agency (1977-83) and the " Actinide Newsletter" which is published by Oak Ridge National Laboratory

.(1981-83).-

Research i for Professor Wehring's doctoral research, he designed and built a unique bent-crystal spectrometer for the measurement of characteristic x rays emitted in fission of U-235. . This was the first measurement of x rays coincident with fission' using a spectrometer capable of resolving Kot x rays of adjacent Z fission fragments.

As a member of the f aculty at the University of Illinois, he initiated and guided multiparameter experimental studies of prompt and delayed x rays and gamma rays emitted by . fission fragments. Besides determining the amounts of particular types of radiation emitted by radioactive fission fragments, these measurements also gave information about the elements formed. in fission, the types of transitions in excited fission fragments, and the nuclear structure of neutron-rich nuclei.

He provided major guidance in measurements of beta rays from U-235 and Cf-252 '

fission fragments and was responsible for the unfolding technique and empiri-cal fitting scheme used in this research. Although the time dependent measurements on the spontaneous fission of Cf-252 are unique, the results of the measurements on thermal-neutron fission of U-235 are more important and were incorporated into fission reactor decay heat standards.

Professor Wehring initiated an experimental program to make direct physical measurements of the nuclide yields in thermal-neutron fission using the time-of-flight technique. A new fission-fragment recoil mass spectrometer, HIAWATHA, was conceived, designed, and constructed. Operating on a unique principle, HIAWATHA achieved 0.5-amu mass resolution for both light and heavy fragments. The best mass resolution previously obtained for this type of experiment was 2.0 amu. An event-by-event energy-loss measurement is used to

1 identify fragment' atomic numbers. The development of this technique required 1 a study of fission-fragment slowing down more detailed than had previously .]

been attempted. 1 I

He also initiated research at the University of Illinois in the area of recoil spectroscopy. By using pulse-shape discrimination on the output of an NE-213

' organic scintillator, neutrons, measured by proton recoil, are sorted from gamma rays which 'are measured by Compton electron recoil. A. spectrometry system was developed and was used to measure energy spectra of neutrons and gamma rays leaking from homogeneous spheres containing neutron sources. The results are compared to calculated spectra as tests of multigroup cross sec-tion sets for materials of interest to fission and fusion reactor development.

Research started at the University of Illinois and continued at North Carolina State University includes the development of the solid state nuclear track detector CR-39 for use as a practical fast-neutron dosimeter and also for use as a research. tool in microdosimetric measurements. Research started at North Carolina State University includes the investigation of advanced alpha-particle detectors made of heavy elements as alternatives to silicon surface-barrier detectors for the " foil-neutralization technique" of alpha-particle diagnostics in fusion reactors 3.ith high neutron backgrounds. CdTe and HgI2 detectors are being considered and tested for radiation response and radiation damage characteristics.

Professor Wehring is also collaborating with 3 faculty members at North Carolina State University on an experimental demonstration of a decrease in tha high-heat-flux erosion of a material surface due to the presence of a strong parallel magnetic field. This Magnetic Vapor Shielding effect has application to high-power switching devices, gun barrels, rail guns, and beam targets. He is the member of the team who has had experience in " pulse power."

Professor Wehring has also participated in experiments using charged particle accelerators at ANL (tandem and linac), ORNL (tandem), and LANL (Van de Graaff).
