چکیده [English]

In this article, different types of cyclotron solid targets and their advantages and disadvantages are discussed and a new design is introduced for solid targets of IBA-Cyclone 30 cyclotrons for the first time. In this new targetry, the number and depth of the back grooves for coolant passage were changed. The target material was placed behind an aluminum drawer for bombardment. For this reason the new targetry was named drawer backings. Thus we were able to bombard powders of the target material. These backings have unique capabilities: metallic salts can be bombarded behind the drawer holders and chemical separation may be performed with higher yields and lower costs with respect to other methods. The bombardment may be repeated many times with the same backing. The drawer avoids the presence of contaminant nuclides in the final product.
