Revision as of 15:23, 31 January 2013
This PASI targets work package concerns high-power-density solid target development and operation, including material studies and target monitoring systems. It is coordinated by David Jenkins.
Contents
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.

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

Overlap with RadiATE
The RadiATE (Radiation damage in Accelerator Target Enviroments) project between the UK and US labs overlaps with the PASI targets UK remit. Particularly in milestones 1.5 (assessing target lifetime due to radiation) and 1.6 (radiation damage studies at an existing facility). There is considerable interest in dissecting irradiated targets for material studies.
Meetings
WP1 meetings may be found in the list of PASI Targets meetings.
