11 - FFTF-LMFBR seal test program, October-December 1973

Description: The objectives of this program are to: (1) conduct static and dynamic tests to demonstrate or determine the mechanical performance of full-size (cross section) FFTF fuel transfer machine and reactor vessel head seals intended for use in a sodium vapor - inert gas environment, (2) develop and demonstrate these FFTF seals or new seal configurations to provide acceptable fission product and cover gas retention capabilities at LMFBR Demonstration Plant operating environmental conditions other than … more

Absorption of electromagnetic rays near the critical density. Quarterly progress report, June 1, 1973--September 1, 1973

Description: An experimental study of the interaction of high-intensity ruby laser radiation with hydrogen gas in a free-jet is described. In these experiments both laser intensity and the plasma frequency can be varied. By monitoring several parameters, including incident and reflected power, x-ray emission and the kinematics of plasma growth, the existence of an anomalous threshold for coupling radiation into plasma energy should be determinable. A discussion of the experiment, including a design drawing … more

Absorption of electromagnetic waves near the critical density. Annual report, 1 December 1972--30 November 1973

Description: The program is an experimental study of the interaction of highintensity ruby laser radiation with hydrogen gas in a free-jet. In these experiments, both laser intensity and the plasma frequency can be varied. By monitoring several parameters, including incident and reflected power, x-ray emission and the kinematics of plasma growth, the existence of an anomalous threshold for coupling radiation into plasma energy should be determinable.

Adding memory to the PDP-9

Description: The University of Minnesota has expanded its PDP-9 memory to the full 32 K word capacity of the machine. The expansion from 8 K to 18 K words, entailing the construction of the Extended Memory Interface, was the most difficult part of the project. The interfacing procedure is described. (WHK)

Annual report, May 1, 1972--June 15, 1973

Description: Work during the period was devoted to completing the new beam line and neutron tunnel, to completing a program of cyclotron modification and orbit studies, to continuing the investigations of the spectroscopy of the rare earth region and in-beam gamma spectroscopy, and to the development of the neutron time-of-flight system. Information is presented under the following headings: experimental program; cyclotron modiftcations, beam diagnostics, and orbit studies; and facllities improvements. (RWR) more
