Book excerpt: Ein Gyrotron wird in magnetisch eingeschlossenen Plasmaexperimenten für Heizung, Stromtrieb, Plasmastabilisierung und Plasmadiagnostik verwendet. In dieser Arbeit wird der erste Entwurf und Bau eines Mehrfrequenz-/Mehrzweck Pre-Prototyp Gyrotrons in koaxialer Technologie vorgestellt, das bei (136)/170/204 GHz mit einer Ausgangsleistung von 2 MW arbeitet. Dies ist der erste Schritt zum Betrieb bei Frequenzen bis zu 240 GHz unter Verwendung der Koaxialhohlraum-Gyrotrontechnologie. - A gyrotron is used in magnetically confined plasma experiments for heating, current drive, plasma stabilization and plasma diagnostics. This work presents the first design and construction of a multi-frequency / multi-purpose coaxial-cavity pre-prototype gyrotron operating at (136)/170/204 GHz with an output power of 2 MW. It is the first step towards operating frequencies up to 240 GHz using the coaxial-cavity gyrotron technology.

Book Synopsis Automated Mode Recovery and Electronic Stability Control for Wendelstein 7-X Gyrotrons by : Wilde, Fabian

Download or read book Automated Mode Recovery and Electronic Stability Control for Wendelstein 7-X Gyrotrons written by Wilde, Fabian. This book was released on 2024-08-07. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic confinement fusion relies on plasma heating and plasma control using gyrotron oscillators providing at megawatt power levels. The operational reliability decreases when operating at the performance limits due to increasing parasitic mode activity. This work demonstrates for the first time the automated, fast recovery of nominal gyrotron operation during a pulse by exploiting the hysteretic gyrotron behaviour after a mode switch being in use at the Wendelstein 7-X ECRH facility.

Book Synopsis MultPhysics Modelling towards the Stabilization of PAN Fibers with Microwaves Based on Experimental Data by : Hofele, Julia

Download or read book MultPhysics Modelling towards the Stabilization of PAN Fibers with Microwaves Based on Experimental Data written by Hofele, Julia. This book was released on 2024-07-10. Available in PDF, EPUB and Kindle. Book excerpt: High energy demand is one reason for high costs of carbon fibers. One option to decrease them is to use microwave heating instead of conventional heating. In this work, steps towards a microwave assisted process during the stabilization phase are presented. In-situ dielectric measurements are performed and a reaction kinetics model is setup in connection to the dielectric loss. This allows to calculate a stabilization degree and fiber temperatures leading to a basic process understanding.

Book Synopsis Systematic Study of Key Components for a Coaxial-Cavity Gyrotron for DEMO by : Franck, Joachim

Download or read book Systematic Study of Key Components for a Coaxial-Cavity Gyrotron for DEMO written by Franck, Joachim. This book was released on 2017-05-11. Available in PDF, EPUB and Kindle. Book excerpt: The physical design of cavity and magnetron injection gun (MIG) for a realistic, DEMO-compatible, coaxial-cavity 238 GHz 2 MW CW fusion gyrotron is developed in this work, having auxiliary frequencies at 170 GHz and 204 GHz. Novel systematic approaches towards multi-frequency mode selection, magnet requirements, and MIG design are presented. Mode deterioration and voltage depression variation due to insert misalignment versus cavity wall and/or versus electron beam are studied.
