The cyclotron of nuclear medicine research group at the Agricultural, Medical and Industrial Research School (AMIRS) has been producing several radionuclides such as 201Tl, 67Ga, 18F and 81Rb for nuclear medicine centers. Gas targets are utilized in a variety of cyclotron producing radionuclides which are used in nuclear medicine centers. We report a method for the design and manufacture of a cyclotron gas target which facilitates both the collection and processing of the krypton gas target as well as the desired 81Rb. In this study a gas target was designed for routine production of 81Rb (for a 81Rb/81mKr generator) through the nuclear reaction natKr(p,2n)81Rb → 81mKr. The incident energy of protons on the target was 26.5 MeV. The gas target was made of stainless steel. The length of the target was 251 mm with double titanium windows, 20 μm in thickness. A production yield of 3.18±0.27 mCi/μA·h was obtained which was more than 80% of the calculated yield (4.1 mCi/μA·h).
