TY - BOOK AU - Marek, Alexander PY - 2023 TI - New Type of sub-THz Oscillator and Amplifier Systems Based on Helical-Type Gyro-TWTs AB - This work presents the development of a new sub-THz source for the generation of trains of coherent high-power ultra-short pulses at 263 GHz via passive mode-locking of two coupled helical gyro-TWTs. For the first time, it is shown that the operation of such passive mode-locked helical gyro-TWTs in the hard excitation regime is of particular importance to reach the optimal coherency of the generated pulses. This could be of particular interest for some new time-domain DNP-NMR methods.Umfang: XXV, 282 S.Preis: 52.00 € PB - KIT Scientific Publishing CY - Karlsruhe KW - passive Modenkopplung KW - Sub-THz KW - Gyro-TWT KW - Ultrakurze Pulse KW - passive mode-locking KW - sub-THz KW - gyro-TWT KW - ultra-short pulses SN - 978-3-7315-1250-9 DO - 10.5445/KSP/1000151835 SE - 324
