One of the near future goals of the strangeness nuclear physics program at Mainz is a precise binding energy measurement of hypertriton Λ3H. Detailed simulations show that lithium is the optimal target nucleus for this experiment. To reach a high luminosity and to minimize energy straggling of outgoing pions, the target is 50 mm long in beam direction and 1 mm wide. To withstand the heating by a 10 µA beam current, the target was embedded in a cooling system. Such a target system was successfully tested under these beam conditions.
