Shielded Door for Cyclotron Bunker 

 The bunker door, especially designed for hot shielded cyclotron, consists of a steel formwork entirely filled with a concrete or barytic concrete casting. The movement is operated by a wheel system connected to the electric gear motor or hydraulic cyclotron bunker door motor. The motor is controlled by an inverter that ensures a mild and linear operation, with acceleration and deceleration ramps.

 The formwork has a double-tooth for the overlapping over the wall. A steel frame is supplied to produce the female double-tooth, which ensures perfect coupling with reduced clearance. The whole inside perimeter of the door has a silicon ring that is completely pressed when the door is closed and therefore allows for a higher sealing of the depression inside the premises.
