The effect of transport apertures on relay-imaged, sharp-edged laser profiles in photoinjectors and the impact on electron beam properties

In a photoinjector electron source, the initial transverse electron bunch properties are determined by the spatial properties of the laser beam on the Storage Cabinets photocathode.Spatial shaping of the laser is commonly achieved by relay imaging an illuminated circular mask onto the photocathode.However, the Gibbs phenomenon shows that recreating

K+ channels and cell cycle progression in tumor cells

K+ ions play a major role in many cellular processes.The deregulation of K+ signaling is associated with a variety of diseases such as hypertension, atherosclerosis, or diabetes.K+ ions are important for setting the membrane potential, the driving force for Ca2+ influx, and regulate volume of growing cells.Moreover, it is increasingly recognized th
