cable shield
3.It was difficult to measure the load voltage directly between inner and outer conductor of cable induced by shield current under low flux X ray.This paper introduces a measurement,pouring a current,which was same as cable approximately photocurrent in X ray test,into the shield of cable with a triocoaxial system,and the load voltage was got.Finally the measured result of typical cable and comparison with the calculation was given with a special load.
8.Both ends of the shield are a "floating" ground in most cases, and this creates a complex circuit network consisting of the complex impedance to ground of the output circuit at one end, the complex input circuit impedance at the other end, and the resistance, capacitance, and inductance of the cable in between.
