High intensity proton beams are needed in the Jyvaeskylae accelerator for radioisotope production. At present the extraction efficiency of 30-70 MeV proton beams is 50-70%. This limits the maximum extracted beam current to about 30 {mu}A. In order to minimize activation of the cyclotron and to allow for higher intensities we have studied the possibility of H{sup -} acceleration with stripping extraction. It was found that beam losses due to residual gas at a normal pressure in the cyclotron do not exceed a few percent as well as the beam losses due to electromagnetic dissociation of H{sup -} ions accelerated up to 75 MeV are lower than 2%. The beam optics calculations show that proton beam can be extracted with an efficiency of 100% and matched with the existing beam line. The plans to develop the production of the {sup 123}I radiopharmaceutical raw material includes a new {sup 124}Xe gas target system. Its advantages are the increase of the yield due to the lowered proton energy and the purity of the reaction product.
