This article concerns apparatus for automatically dispensing evaporation charges in the form of premeasured discs from a magazine to an evaporation vessel. The apparatus features a cam-driven shuttle having a charge-receiving cup whose bottom is formed by a movable shutter. Under the action of the drive cam, premeasured source pellets are received from the magazine, transported to the evaporation vessel, and discharged. In the course of automated evaporation processing, it becomes necessary to automatically replenish the charge being evaporated. In the past, this has been accomplished by feeding sections of wire to be evaporated by means of an indexing apparatus to the evaporation vessel.
