Fusion Futures: Development of a Gyrotron Cavity Test Rig

The objective of this work package is to develop a test rig design for testing prototype gyrotron cavities simulating the: • Internal thermal load and associated cooling efficiency • Pressure forces • Vacuum compatibility The test rig would include a thermal head that is inserted into prototype cavities to mimic the induced ohmic loads from the cavity electric field profile. The head could be designed for a specific gyrotron cavity, but the concept adaptable to cavities with diameters in the range of 30 to 50mm, an...
