A device comprising an RF cavity enclosure including a tubular section having a plurality of interior structures radially or axially arranged which forms an unobstructed inner hollow center within the tubular section. Each interior structure of the plurality of interior structures includes side walls between which is formed an internal hollow sub-cavity. Resonating cavities exist between adjacent interior structures to produce a resonating frequency response. Vents are formed in at least one side wall for permeation of a gas into the internal hollow sub-cavity. A high-power microwave system and method of manufacture are provided.

A plasma source is provided that includes multiple metallic blocks. A toroidal plasma chamber and a transformer are substantially embedded in the metallic blocks. The toroidal plasma chamber includes a gas inlet configured to receive a process gas and a gas outlet configured to expel at least a portion of the process gas from the plasma chamber. The plasma chamber also includes multiple linear channel segments, multiple joints, an inlet joint, and an outlet joint machined into the metallic blocks. Each of the inlet joint, the outlet joint, and the joints connects a pair of the linear channel segments. The linear channel segments, the joints, the inlet joint and the outlet joint in combination form the toroidal plasma chamber. The gas inlet is disposed on the inlet joint. The gas outlet is disposed on the outlet joint. An inner angle of each of the joints is greater than about 90 degrees.

An ion generating device including a time-varying electromagnetic power source; and a multi-antenna ion source including a plurality of live antennas electrically coupled to the power source; and a grounded antenna. A neutron generator, including a time-varying electromagnetic power source; a hermetically-sealed tube; a multi-antenna ion source within tube, the multi-antenna ion source including a plurality of live antennas electrically coupled to the time-varying electromagnetic power source; and at most one grounded antenna; an extractor adjacent to an aperture of the multi-antenna ion source; at least one magnet generating a magnetic field substantially parallel to a longitudinal axis of the multi-antenna ion source; a target within the hermetically-sealed tube; and a plurality of electrodes for accelerating and/or decelerating ions toward the target, where the power source operates at a frequency corresponding to a cyclotron frequency defined by a value of the magnetic field within the multi-antenna ion source.

A light source module includes a light source having an optical axis, a fan for providing a cooling airflow and a deflector disposed between the light source and the fan and directing a flowing direction of the cooling airflow. The deflector includes a first air duct connected between a first side of the light source and an air outlet of the fan, a second air duct connected between a second side of the light source and the air outlet of the fan, and a first airflow control assembly controlling the first air duct in a communicating state or a non-communicating state and having a first control shaft and a first airflow passing portion rotating about the first control shaft. The first control shaft is inclined to the optical axis so that a first angle is formed therebetween. The first angle is between 0 and 90 degrees.
