Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

Results of a simulation are presented and experimental observations of the generation of superradiance pulses in the 4 and 2 mm wavelength ranges as a result of the rectilinear motion of a subpicosecond high-current electron beam through a periodic retarding system are described. In the 4 mm range the microwave pulse power reached 10-15 MW with a duration of 150 ps.
