CYCLOTRON BUNKER VAULT DOORS
RADIATION SHIELDING FOR PET-CT ISOTOPE MAKING
HIGH SPEED CYCLOTRON PLUG DOOR OPERATION
The cyclotron door movement is produced by an electrical gear-motor connected to a trailer wheel by means of a appropriately designed chain drive, and tested by MODEDOOR for specific cyclotron bunker needs. The motor is of the double-shaft exit type, so it is possible to perform emergency movements of the door by means of a handwheel. This handwheel operates directly on the motor and is used by opening a port located on the motor covering case. A micro-switch senses the insertion of the handwheel and interrupts the supply current to the motor thus allowing manual movement of the door. The use of an inverter type motor driver and PLC Controller supplies the power to the motor and serves two important functions. 1-Regulation of both, opening and closing velocity 2-Regulation of the acceleration and deceleration ramps in proximity to the stop position.
