Remembering Charles E. Till
Charles E. Till
Charles E. Till, an ANS member since 1963 and Fellow since 1987, passed away on March 22 at the age of 89. He earned bachelor’s and master’s degrees from the University of Saskatchewan and a Ph.D. in nuclear engineering from Imperial College, University of London. Till initially worked for the Civilian Atomic Power Department of the Canadian General Electric Company, where he was the physicist in charge of the startup of the first prototype CANDU reactor in Canada.
Till joined Argonne National Laboratory in 1963 in the Applied Physics Division, where he worked as an experimentalist in the Fast Critical Experiments program. He then moved to additional positions of increasing responsibility, becoming division director in 1973. Under his leadership, the Applied Physics Division established itself as one of the elite reactor physics organizations in the world. Both the experimental (critical experiments and nuclear data measurements) and nuclear analysis methods work were internationally recognized. Till led Argonne’s participation in the International Nuclear Fuel Cycle Evaluation (INFCE), and he was the lead U.S. delegate to INFCE Working Group 5, Fast Breeders.

Development of an electron cyclotron heating (ECH) mirror antenna and MW gyrotrons for power modulation experiments in GAMMA 10 has been started in order to generate and control the high heat flux and to make the edge-localized mode (ELM)-like intermittent heat load pattern for divertor simulation studies. A peak heat flux of more than 10 MW/m2 on the GAMMA 10 axis has been obtained during ECH injection within the available power of ECH. This value almost corresponds to the steady-state heat load of the divertor plate of ITER. However, we need a substantial upgrade of the heating power to approach the ITER level ELM energy density. We carry out a design study for a mirror antenna and higher power gyrotrons in order to generate higher intermittent heat flux in GAMMA 10 tandem mirror for future divertor simulation studies.
