	The Superconducting Cyclotron (CS) is a three sectors, compact accelerator with a wide operating diagram, capable of accelerating heavy ions with q/A from 0.1 to 0.5 up to energies from 2 to 100 MeV/u. Recently a significant upgrade has been proposed to increase the light ion beam intensity by means of extraction by stripping. For the implementation of the new extraction mode, many relevant modifications are needed in the median plane. The biggest upgrade action is the replacement of the present superconducting magnet with a new one, compatible with the beam trajectory and envelope in the extraction by stripping. The extraction by stripping mode implies the installation of two stripper systems, one in a hill and the other in a valley, that allow to extract all the ions requested by the users. Finally, since the present electrostatic extraction mode will be maintained, several relevant mechanical issues have to be faced when switching from one extraction mode to the other one, the location of one electrostatic deflector being the same as the stripper system. The focus of this paper will be the presentation of the different mechanical features involved in the upgrade.

WEA02	The Developments of the RF System Related to the K-800 Superconducting Cyclotron Upgrade	262

	The K-800 superconducting cyclotron has been in operation at Laboratori Nazionali del Sud for almost 25 years. It has been subjected to continuous upgrades and modifications since 1994: the RF couplers have been redesigned, the new dees have been changed from aluminium to copper, as has the new central region from radial to axial injection of the beam, the hybrid configuration solid state - tube of the power amplifiers, the digital LLRF, etc. The next scheduled important upgrade of the Cyclotron mainly consists in a new extraction beam line able to support the increase of the beam current intensity. The accelerated beam will be extracted in two ways: by stripper and by electrostatic deflector and, consequently, one of the most important features of the new upgrade is the new cryostat. Further upgrades and refurbishments of the other main parts of the cyclotron, such as a new liner, the modification of the RF cavities and dees, the refurbishment of HLRF-LLRF, the insertion of the stripper extraction system, to name but a few, are in progress, too. This work focuses on the RF system upgrade.
