Notes:
Critical currents in cylindrical granular Al thin films of different thicknesses and electron mean free paths have been measured as a function of temperature. Experimental values of critical current tiIc in all specimens are less than the theoretical pair-breaking current. The observed temperature dependence of I c is in agreement with the theoretical one near the critical temperature, but not at lower temperatures. Effects of the manner in which the current terminals are attached to the specimen and of a deliberately applied weak spot on I c have been investigated. The dependence of I c on the rise time and the width of the pulse current has been studied.
