Abstract : The penetration of perpendicular magnetic pulses of 1.6 micro sec duration through a type II superconducting plate has been observed in a perpendicular magnetic field. The plate was a single crystal of Pb with 8% In and had a thickness of 1.65 mm. The time delay of the transmitted pulse as well as the height of the transmitted pulse can be used to find the value of an effective resistivity. A change delta H of the superimposed field which aids the pulsed field causes anomalously large pulse penetration. The delay time is not affected by a small change of the superimposed field, indicating that the effective resistivity does not change, but that the change of the superimposed field increases the pressure against the pinning centers and aids the pulse penetration.
