KLF beamline meeting - December 5, 2024

Agenda

• Announcements

• FLUKA simulations with 20% CPS radiator (Pavel)

• W-plug temperature estimates for 20% radiator (Hovanes)

• Beamline studies with GEANT4 (Richard)

• Any other business

Minutes

Present: Hovanes, Pavel, Vitaly, Tim, Moskov, Eugene, Igor, Sashi, Beni, Richard, Mikhail, Marshall.

• Pavel continues studying the option of 20% radiator. He included the tungsten material of KLF Active Collimator ~50cm in front of the KPT assembly.

• Radiation dose rate from neutrons doubled compare to that without AC. γ-dose-rates did not change so much.

• Tim commented that Active Collimator is attached to the KPT assembly and the long distance between KPT and AC may cause elevated radiation rates.

• Eugene would like to see the same simulation with 10% radiator as he thinks it is suspicious that the temperature of the tungsten plug did not change. Hovanes pointed out that we have copper block around the Be-target with 20% radiator option. This takes away 2.8 KW power from reaching the tungsten plug.
