Outline of Final Research Achievements

The goal of this project is to construct a compact device for observing dispersed emission spectra. The device measures the wavelengths of the incident photons through the energies of photoelectrons emitted from a photocathode. We have remodeled a commercial photomultiplier and tried to measure the dependence of the energies of photoelectrons on the wavelength of the incident light, finding that photoelectrons can be detected without applying voltage to the first dynode. The cause of the fluctuation of the signal originates form the thermal electrons (1 V) instead of the ripple of the high voltage power supply (0.05 V). Separation of the pulses of thermal electrons and photoelectrons is necessary to fabricate a device for observing dispersed emission spectra.
