1. 1Managed by UT-Battelle for the U.S. Department of Energy NF Splash Mitigation 12 July 2011 Neutrino Factory Mercury Pool Splash Mitigation V.B. Graves IDS Videoconference July 12, 2011

2. 2Managed by UT-Battelle for the U.S. Department of Energy NF Splash Mitigation 12 July 2011 Splash Mitigation Study 2 assumed a particle bed of tungsten balls to minimize effects of jet entering pool Many other feasible concepts to accomplish this function Simulation/analytical studies may be useful to limit options Pool circulation and drainage locations also need to be studied Prototypic testing needed for comparison & final determination

3. 3Managed by UT-Battelle for the U.S. Department of Energy NF Splash Mitigation 12 July 2011 Issues & Questions Do jet & beam drill hole into mercury pool? Narrow or wide channel? Deep or shallow? How & where to incorporate drainage? Upstream or downstream? How to protect downstream beam window from waves and splashes? Is the steady-state condition calmer than start-up? Can these mitigation options be easily simulated? What about doing water tests?
