A dynamic beam window for coupling accelerator and reactor core in an ADS / Caspers, Fritz (CERN) ; Mueller, Alex C. (ACM Consult GmbH, Mainz)
During the many fruitful discussions and presentations at this EUCARD2-workshop we all were once more reminded of the respective technical short comings of the two solutions bringing an intense proton-beam on a molten-lead spallation target housed inside a fuel-loaded reactor. These are namely the window-less target solution where the accelerator is completely unprotected from accidentally back-streaming target material or the window solution with it’s inherent danger of catastrophic failure. [...]
