| 520 | _ | _ | |a In recent years, the interest in low energy compact accelerator-driven neutron sources (CANS)has increased worldwide. The focus of this interest is shifting more and more from smalluniversity based CANS to powerful high flux CANS that have the potential to replace currentreactor based neutron sources and possible alternatives to spallation sources.Within the framework of the Jülich High Brilliance Neutron Source (HBS) project, a high fluxaccelerator based neutron source is developed. One of the key components as well as themain power-limiting factor is the target that releases neutrons from the impinging protonsvia nuclear reactions. Since the neutron yield of nuclear reactions is quite small, this iscompensated with a high proton current. However, the high proton current leads to a strongheat release inside the target. At the same time the target has to be very compact to allowthe subsequent extraction of a neutron beam with a high brilliance. Overall, this leads tounique requirements of the HBS target given by a 70 MeV pulsed proton beam with a peakcurrent of 100 mA and an average thermal power release of 100 kW inside the target with asurface area of 100 cm².A solid tantalum target prototype with an innovative micro channel water cooling structurewas developed, manufactured, and successfully tested to match these requirements. Knownproblems from low energy targets like blistering, limited heat dissipation and highthermomechanical stresses have been consequently minimized during the development.Feedback from the production process helped to eliminate known weak points of theprototype. The coolant erosion resistance of the micro channel structure was demonstratedin a six-week endurance experiment, to exclude possible concerns on this. Furthermore, thetarget was successfully high heat flux tested at ~1 kW/cm² in the electron beam facilityJUDITH 2 and with these measurements the design simulations of the target could bevalidated. The specifics of the HBS target concept as well as the results of the experimentalheat load and erosion tests will be presented. |
