Low energy sputtering yields at grazing incidence have been investigated experimentally using a quartz crystal microbalance QCM technique. This method involved precoating the QCM with a thin film of… (More)
The tritium plasma experiment (TPE) is a unique facility devoted to experiments on the behavior of deuterium/tritium in toxic (e.g., beryllium) and radioactive materials for fusion plasma-wall… (More)
Ion thrusters offer the potential to enable many future interplanetary robotic missions presently under consideration by NASA. To realize the benefits offered by these low thrust devices, the… (More)
