Abstract

Provided is a pellet feeder for supplying pellets of a vaporisable material to a vaporisation site in a vacuum chamber, which pellet feeder comprises a pellet holder (1), a gating means (2), a lateral displacement means (3) and a retractable pellet dispenser (4); wherein the pellet bolder comprises an exit (5) through which pellets may be delivered, the gating means is located proximal to the exit of the pellet holder, and the gating means is capable of regulating delivery of pellets from the pellet holder to the lateral displacement means such that a single pellet is delivered to the lateral displacement means at any one time; wherein the lateral displacement means is capable of delivering a single pellet at any one time to the retractable pellet dispenser; and wherein the retractable pellet dispenser is adapted to receive a single pellet from the lateral displacement means at a receiving position, and the retractable pellet dispenser is capable of being displaced to a dispensing position proximal to the vaporisation site in the vacuum chamber, dispensing the pellet to the vaporisation site, and retracting to the receiving position.
