  7. Upgrade to ISIS target station 1 A Section AA A High temperature tungsten pellets Helium cooling 800MeV, 160kW, 50Hz 90kW heat removed in water Section view of current target Section view of target concept Target being in pellet form allows high temp operation without high stresses No cooling water to moderate neutron flux Scope for more than 160kW? Ref: Sievers 2003.

  8. NF-IDS and EUROnu Targets Work Program (30 months) • NF-IDS primarily focused on baseline recirculating mercury target • With input of EUROnu task broadened to include alternative tecnologies (solid & flowing powder targets) • Must achieve cost estimate of target system so implies target selection • Selection criteria for choice of target • Work Program • First meeting 15th to 17th December 08 at CERN • Comments on proposed selection criteria and work program are welcomed.
