For investigating luminescence during and after electron bombardment of a phosphorous anode, as well as excitation of fluorescence and phosphorescence. Luminescence can also be observed following irradiation of the phosphorous anode with ultraviolet light.
Cathode heating voltage: Uh < 7.5 V, Ih < 1.8 A
Anode voltage: Ua < 5 kV
Anode current: typically Ia = 150 µA at Ua= 4.0 kV
