Figure 1. Simplified sketch of the TCA design (a) The design consists of the neutron production target T, the moderator and the reflector. Molybdenum samples are schematically shown placed on the sides and downstream of the target. (b) Design of the activator for the test beam experiment at the PSI. The target position, dimensions and its cladding have been adapted to the existing target holder (equipped with a dedicated water cooling circuit). Beryllium is isolated from the moderator/cooling medium by a thin aluminium layer to prevent beryllium getting into the cooling system.
In the 99mTc Cyclo-Activator (TCA; Figure 1a), neutrons are produced by interaction of the cyclotron proton beam on the beryllium target. Neutrons emerging from the target are moderated to the energy range of interest by heavy water, which simultaneously serves as cooling medium. The optimal molybdenum sample, cylindrically shaped, is placed around the target covering a large solid angle and enabling a large neutron fraction to be captured. Additionally, the graphite reflector surrounding the molybdenum sample increases the probability of capture on 98Mo by
