Revision as of 15:57, 21 August 2012

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.
  • Powers in Watts are time-averaged; energies in Joules are for an individual pulse. The kJ/pulse column shows beam energy, whereas the volumetric (W/cm3, J/cm3) shows the heat deposited in the target at the most intense point.
  • Temperatures are the max and min attained by the target material during operation. Rise per pulse is the highest ΔT found anywhere in the target.

  4. Rough calculations by Stephen Brooks using the J/cm3 column and densities and specific heats of materials from the web at room temperature. Should be replaced by more accurate values if possible.

Future Targets

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