Condensed Matter Physics Laboratory

Positron Annihilation Laboratory

A state-of-the-art positron annihilation lifetime spectrometer allows measurements of lifetimes as short as 0.2 nsec to an accuracy of better than 0.01 nsec. Output data are automatically stored, and can be printed, plotted or transferred to the University’s Mainframe Computer for analysis. This apparatus allows investigations of samples under various physical conditions.

Other instrumentation in this laboratory includes a high resolution Ge detector and a helium
refrigeration system which can be used to perform experiments in the temperature range 10oK to 400oK. In addition, a large amount of digital nuclear instrumentation is utilized in the positron laboratory.
