“…Instrumental to the gyrotron R&D is the new Fusion Long Pulse Gyrotron Lab (FULGOR) at KIT, a test stand capable of 10 MW DC CW operation [38]. The capabilities of the main high-voltage DC power supply, delivered in late 2017 by Ampegon AG (Turgi, Switzerland, www.ampegon.com), are up to 90 kV / 120 A for 3600 s and 120 kV / 120 A in short pulse.…”

“…KIT is currently funding a significant extension of its existing gyrotron test stand. That new test stand named FULGOR will allow the test of gyrotrons with up to 2x2 MW RF output power with dual-beam output [25]. The installation of the main part, the 10 MW CW high voltage DC power supply (HVDCPS) has been completed in spring of 2018 by Ampegon, Turgi, Switzerland.…”

During the ongoing pre-concept phase (2014 – 2020) for a possible future European DEMOnstration Fusion Power Plant (DEMO) the activities within EUROfusion WP HCD EC Gyrotron R&D and Advanced Developments are focusing on options for near-term solutions, and, at the same time, on long-term even more advanced options. The near-term target for DEMO is to realize pulsed operation. According to the current baseline it will probably use an EC system operating at 170 GHz and 204 GHz is being assessed, whereas the long-term target aims for steady-state operation and frequencies for current drive up to 240 GHz. Common targets for both are an RF output power per unit of significantly above 1 MW (target: 2 MW) and a total gyrotron efficiency of significantly higher than 60 %. Frequency step-tunability and multi-purpose/multi-frequency operation have to be considered. Those targets shall be achieved by considering the coaxial-cavity gyrotron technology and advanced technologies for key components (e.g. CVD diamond-disk Brewster angle window). Advanced simulation and test tools are complementing the research and developments. Gyrotron development is additionally supported by a significant investment into a new multi-megawatt long-pulse gyrotron test stand which is under final installation at KIT currently.

“…Vital to the future gyrotron R&D is the new Fusion Long Pulse Gyrotron Lab (FULGOR), a test stand able to support the development of up to 4 MW continuous wave gyrotrons at frequencies up to 240 GHz [9]. Within the EUROfusion project, the basic specification for a super-conducting 10.5 T cryogen-free magnet for FULGOR has been prepared.…”
