Emission and Excitation Mechanisms of Phosphors
In this chapter, basic concepts involved in luminescencewill be discussed.Wewill take a closer look at a number of excitation mechanisms which are involved in generating luminescence and processes which lead to luminescence, taking illustrative examples from luminescentmaterials applied in fluorescent lamps and cathode ray tubes.With respect to fluorescent lamps, we will restrict ourselves to d...
متن کاملPhotocathode Studies for the Spear3 Injector Rf Gun*
The electron gun for the SPEAR3 injector operates with a warm thermionic dispenser cathode immersed in a 1.5-cell RF structure. At each injection cycle the gun accelerates several thousand electron bunches up to ~3 MeV during a 2.5us rf pulse. The individual bunches are then compressed by an alpha magnet and a travellingwave chopper selects 3-5 bunches so they don’t cause beam loading to the li...
متن کاملAssessment of indoor cancer linked to accumulated radiation dose from different types of television sets in dwellings
Exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. Measurement of the annual radiation dose hazards was performed using a halogen-quenched GM tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. The GM tube was plac...
