This panel looked at the mission of ITER, and how the US should address the present plans, and considers a number of alternative plans to arrive at the eventual goals of ITER. The panel considered three major approaches which have been discussed on t

Changes of ultrasonic transit times in compression‐annealed pyrolytic graphite (CAPG) were measured as a function of temperature (4–300°K at atmospheric pressure) and of pressure (0–20 kbar at 295°K). From the low‐temperature results, obtai

The μ+ depolarization rate in diluteAlGd alloys containing 50 and 450 atomic ppm Gd was measured in a transverse field of 80 Oe over the temperature range 6–300 K. For both alloys, A increased dramatically above 200 K, reaching values of 0.69 and

Polycrystalline Al─Cu samples containing 0.5, 2.0 and 4.0 wt.% Cu were quenched, after homogenization, from a temperature of 823 to 200 K. Positron annihilation Doppler broadening measurements were then made after isochronal annealing steps with 30

Positron annihilation Doppler broadening measurements were made on quenched aluminium single-crystal and polycrystal samples as a function of isochronal annealing. Changes in the annihilation lineshape due to clustering of vacancies were observed. Th

Measurements of stress pulses induced in pyrolytic graphite samples by a pulsed electron beam and monitored by an optical interferometer technique are described. The method yields values of Gruneisen tensor components and longitudinal elastic wave sp

We present the first results of a study of the effects of varying impurity concentration on the temperature dependence of the depolarization rate of positive muons implanted into vanadium. Data are reported for the most highly purified polycrystallin

Positron annihilation is a sensitive technique for probing defects in metals and it has recently been shown to be a valuable tool for the study of radiation damage. After an introduction to the three basic experimental methods (angular correlation, D

From measurements of the inertial thermoelastic stress produced by pulse heating a portion of a sample, the Gr\"uneisen parameters of silicon and aluminum as a function of temperature were obtained directly between 5 and 290 \ifmmode^\circ\else\textd

Absorption of intense light, of photon energy greater than the bandgap, produces changes in the optical properties of semiconductors. The induced absorption produced by 1.06‐μ laser light in high‐resistivity single‐crystal silicon wafers was m
