The thyratron stroboscope was designed using a multi-circuit transformer, condensers, resistances, a thyratron tube, and a disk. Host of the material was personally constructed in the laboratory and the whole assembled according to Figure 1 and placed in a case. Tests were made with the instrument and although it displayed some flaws, results were generally satisfactory. The chief disadvantage found was lack of illumination from the tube. Some of the advantages are simplicity of operation, compactness, portability, absence of moving parts, and low cost. / Master of Science
