Experience upgrading 18F target and control system of an unshielded RDS112

The 18F target and the Control System of an unshielded CTI RDS112 cyclotron have been upgraded in order to increase 18F-fluoride production and meet new radioprotection requirements of the National Regulator, among other goals. At present, maximum capacity of 18F-fluoride production of the cyclotron is about 5 times bigger than originally with a higher reproducibility and more flexibility given by two targets with different rated filling capacities. Also, safety and procedure interlock systems have been integrated and validated in the new Control System.
