Abstract

The use of a beam of heavy ions to heat a target for the study of warm dense matter physics, high energy density physics, and ultimately to ignite an inertial fusion pellet, requires the achievement of beam intensities somewhat greater than have traditionally been obtained using conventional accelerator technology. The research program described here has substantially contributed to understanding the basic nonlinear intense-beam physics that is central to the attainment of the requisite intensities. Since it is very difficult to reverse intensity dilution, avoiding excessive dilution over the entire beam lifetime is necessary for achieving the required beam intensities on target. The central emphasis in this research has therefore been on understanding the nonlinear mechanisms that are responsible for intensity dilution and which generally occur when intense space-charge-dominated beams are not in detailed equilibrium with the external forces used to confine them. This is an important area of study because such lack of detailed equilibrium can be an unavoidable consequence of the beam manipulations such as acceleration, bunching, and focusing necessary to attain sufficient intensity on target. The primary tool employed in this effort has been the use of simulation, particularly the WARP code, in concert with experiment, to identifymore »

Several projects initiated in the past year at the Heavy Ion Accelerator Laboratory have been brought to satisfactory conclusions and a number of new projects have been started. These new projects are logical extensions of our inquiries into nuclear structure through radioactive decay and in-beam spectroscopy. The collaboration efforts at Super-HILAC at Berkeley with Professor J. O. Rasmussen and Professor N. Cue at SUNY/Albany have proved to be very effective and productive. The argon and krypton data from the Super-HILAC at Berkeley were analyzed to study x-rays in heavy ion collisions. Studies on millisecond isomer in $sup 198$Tl were completed.more »« less

The studies of decay properties of several short lived neutron deficient isotopes were conducted using the Heavy Ion Accelerator at Yale. These studies are chosen to complement the in-beam studies, furnishing energy-level data on the same nuclei. The life-time studies on the excited states of several nuclei were completed. Studies on millisecond isomers of Pb, Os and Ir are being conducted. The measurement of the K-shell ionization with fully stripped projectile using various heavy ions have been carried out. The 1 MeV Dynamitronn at SUNY/ALBANY was extensively used for the alpha -radiative capture studies on /sup 26/Mg, / sup 29/Smore »« less

Bakhru, H. January 1977

The 1975--77 contract year remained very active in productivity and has shown several significant results. The studies on short-lived radioactive isotopes and in-beam spectroscopic studies were conducted on many nuclei using the Heavy Ion Accelerator at Yale. The published results are listed in the appendix. Studies on millisecond isomers in the region of Pb, Os, and Ir have been conducted; and this program has been concluded this year. The 4 MeV Dynamitron Accelerator at SUNYA has been extensively used to study alpha capture reactions on /sup 29/Si, /sup 26/Mg, /sup 31/P, /sup 35/Cl, and /sup 37/Cl. High resolution studies ofmore »« less
