摘要：

The target design parameters of the JET pellet Centrifuge are pellet repetition frequencies up to 10Hz with a velocity range 100-500ms(-1). Prior to the 1997 the performance was nor reliable, the 4mm cubic pellets of deuterium ice were often undersize and the efficiency of delivery low A number of mechanical design changes and improvements to control systems have subsequently been made, culminating in successful exploitation of the centrifuge in the 1998-9 JET programme. The system and its recent improvements will be discussed. Finally, an in-vessel track for high-field side pellet launch, installed in the 1999 shutdown, will be described. Operational experience and performance for inboard and outboard pellet injection into Jet plasmas will also be presented.
