The interaction of the dusts with the electron-ion plasma background yields a dust-dust interaction force that is attractive. The latter can hold the dust grains in various stable and metastable cluster configurations. The predicted few-dust configurations agree well with the results from an experiment and a molecular dynamics simulation.
Rotation of dust clusters in an unmagnetized dusty plasma under different gas pressures is experimentally studied. Clusters containing different numbers of charged dust grains are found in different horizontal planes. The mechanism behind the dust rotation is investigated by using molecular dynamics simulations. The experimental and simulation results show that the radial confinement potential plays an important role in determining the properties of the cluster rotation under given gas pressure or temperature.
This note illustrates the operation of a simple optical shutter with an opening time of fractions of a millisecond. The shutter can be used to produce a square light pulse from a cw laser such as the He-Ne laser or tunable dye laser.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
