B01 - Broadband sub-THz high-power amplifier system for high-field pulsed DNP

In Phase 2 of Project B01, the pre-amplifier chip developed in Phase 1 will be integrated into a scalable power-combining array with feedback control, enabling active phase and amplitude optimization of each chip. All key Gyro-TWT components will be fabricated using a novel 2-photon 3D printing technique for compact microwave structures. The array will be used in the first CW DNP-NMR experiments with watt-level output power and integrated with the Gyro-TWT to form a prototype high-power amplifier system, capable of producing up to 1 kW at 263 GHz.
