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, and cavity length 20 to 30mm. Ideally, the thermal profile would be close to consistent with the E-field’s power deposition profile and capable of power densities exceeding 30MW/m2. ## CPV classification Engineering design services Design consultancy services Specialty design services Source Find a Tender (UK) · Notice ocds-h6vhtk-047243-2024-06-24T16:49:07+01:00 [View official notice](https://www.find-tender.service.gov.uk/Notice/ocds-h6vhtk-047243-2024-06-24T16:49:07+01:00) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
