Abstract: An air-guiding assembly for reducing the wind drag is provided at a tail end of a vehicle body and has a hollow frame. The frame is constituted of a plurality of air-guiding plates. These air-guiding plates are each formed into a curved shape. An airflow path is formed between the air-guiding plates. The front end surface of the frame is formed with an intake port, and the rear end surface thereof is formed with an exhaust port. The intake port and the exhaust port are in fluid communication with the airflow path. The area of the intake port is larger than that of the exhaust port, so that the exhaust port acts as a nozzle. When the airflow generated in driving is compulsively guided into the intake port of the frame to pass through the airflow path and then is guided out via the exhaust port, an invisible wind wall is formed in the rear of the vehicle, thereby reducing a whirlwind region in the rear of the vehicle. Therefore, the airflow is smoother and thus the driving efficiency is improved.

Abstract: A mechanically tunable magnetron injection gun (MIG) provides an annular, relativistic beam of electrons for injection into an axially aligned magnetic field of a gyrotron-class device. The electron emitter encircles a center electrode. Turning a knob adjusts the center electrode's axial position relative to the rest of the cathode. The adjustable center electrode provides an effective means for local field adjustment. The center electrode is located in a particularly sensitive electric field region and adjusts the electric field so as to tune the electron beam from the inside out. Adjusting the center electrode position while the device is in operation is a means for providing mechanical tunability (with respect to beam quality and transverse-to-axial velocity ratio) for the MIG.
