Abstract
PURPOSE: To prevent reflection in the connection part by matching input and output impedance in the transmission line on the signal generating/sensing side and arranging a constitution so that both inner and outer conductors may be connected in a smooth shape.
CONSTITUTION: If super high-speed pulse light is radiated into photoelectron emission cathode 6, super high-speed electric pulse is generated. Electric pulse is transmitted to coaxial transmission line for characteristic impedance 2R consisting of outer conductor 10 and inner conductor 11 and resistor 9 for resistance 2R through transmission line for the same characteristic impedance R composed of by-pass 2 and support rod 4 as well as of metal container 8 and support rod 4. Consequently input impedance R of this parallel circuit becomes R. In addition, smooth-shaped inner and outer conductor, i.e. columnar support rod 4 tapering in diameter near the support element 9 is finaly connected in such manner that it may match the orifice of support element 9. For this reason, reflection does not occur at the connection point. Under this constitution, it is possible to prevent reflection of electric pulse in the connection part.
