This work package concerns high-power-density solid target development and operation, including material studies and target monitoring systems. It is coordinated by David Jenkins.

Existing Targets

Milestone 1.1 requires a review of existing (or previously constructed or under-construction) high power targets, whether for neutron spallation or otherwise.

NB:

  • 0 in columns for pulses indicates CW operation.
  • X (@Y) power indicates that X is the design power but has only achieved Y megawatts in operation so far.
  • The pulsed energy column shows the energy in each beam pulse, whereas the volumetric power (energy) column shows the heat deposited in the target at the most intense point.

Future Targets

Milestones 1.2 and 1.3 require knowledge of the requirements for future high power target projects and candidate target materials.
