The techniques evaluated are DC method and Single Photoelec­tron Counting method both using photomultiplier tubes. The photomultiplier tubes used are HTV-R132(S10) and HTV-R376(S20). Optimum values of applied voltage and threshold level of the multiplier tubes obtained by experiments are shown. The best signal sensitivity of 4.5 photo-electrons per second for a counting time of 10 seconds is acquired for HTV-R376 which is cooled down to -30 °C. This means the light power of 2.8x 10⁻¹⁷ w (6328 Å) can be detected by the observation of 10 seconds.
