A widely distributed commercially available target station for the irradiation of solid targets is the COSTIS system. The system is specified for beams up to 500 W and is equipped with a front side He-cooling and water cooling on the back side. The target itself has a coin shape with a diameter of 24 mm and thickness of 2 mm. This recommends the system for irradiation of thin targets like foils but it is also useable for irradiation of metal and oxide powders. However the irradiation of powders and granulates is limited due to the dimension of the target cap-sule. A setup of a capped closed target is hardly achievable. The purpose of this work was the modification of the COSTIS target station for the use of thicker target capsules. This shall enable the more easy and safe handling and irradiation of powdery targets and the use of lockable target capsules.
