Scope
Microbeam radiation therapy is novel and highly promising technique for cancer treatment. It relies on high-intensity, high-dosage micrometer-scale X-ray beams produced by electrons hitting a fast-rotating body called the X-ray anode. It is to be designed and optimized to withstand 1.5 MW of heat load to suit human treatment. To verify this never-before-seen heat flux load, an equivalent prototype is to be built and tested to validate the design.
Results
Validation method and numerical simulation model for ultra-high heat flux loads, Experimental data on the influence of tungsten focal track thickness and manufacturing process on surface degradation, preliminary data on the feasibility of 1.5 MW X-ray source prototype design
Surface roughness vs number of test cycles
Validation test set-up and tested tungsten surface
