	The LNS Superconducting Cyclotron is an isochronous 3-sector compact machine with a wide mass-energy range of heavy ions: beams from protons to lead from 10 to 80 AMeV have been accelerated for the past 20 years. The extraction efficiency is low since a big percentage of the accelerated beam is lost on the electrostatic deflector. Recently, the demand of intense light ion beams, A<20, arose to study rare processes such as the nuclear matrix element in the double charge exchange reactions. Extraction by stripping has been envisaged to increase the maximum intensity by a factor 10-100, so to reach beam power values of few kWatt. Here the feasibility study of the new extraction for this range of ions is presented. The new beam dynamics features have been evaluated and, as a consequence, mechanical constraints have been considered too. It emerges that a new wide extraction channel fulfils the beam requirements. Therefore, a new cryostat has to replace the present one. A first feasibility study of the new cryostat has already accomplished by the PSFC of MIT. A more complete technical design report is under preparation to have the necessary elements to estimate costs and time schedule.

	A compact isochronous cyclotron able to deliver a 10 mA proton beam has been studied for the IsoDAR experiment, which aim is to search sterile neutrino and to investigate the neutrino-electron scattering. The IsoDAR cyclotron has been designed to accelerate high current beam for any ion with q/A=0.5 up to the maximum energy of 60 AMeV. In the IsoDAR experiment H²⁺ ions will be used. However, this cyclotron is also able to accelerate D⁺ or D- ions. In this operational mode, it could be an excellent driver for radioactive facilities with a full beam power of 60 to 120 kW. The advantages to use IsoDAR cyclotron as driver for the RISP (Rare Isotope Science Project) facility in Daejeon, Korea, will be described. The different kinds of extraction by electrostatic deflectors and by stripper, as well as the different advantages and disadvantages will be described too. The expected beam intensities for light ions as 12C⁶⁺, 16O⁸⁺ and 20Ne¹⁰⁺ will be also presented.
