A connector is configured to electrically connect a plasma emitter array with an identification chip to a power supply controller, and to further mechanically support the emitter device supporting the array during use. Cooperating components of the connector and emitter device form a magnetic latch assembly: the connector includes one or more magnets flush with a top receiving surface of the connector, and one or more alignment pegs extending outward from the receiving surface; the emitter device includes a steel plate attached to a substrate, and one or more holes disposed through the plate and the substrate. The holes align with the alignment pegs and the magnets attract the plate and secure the emitter device against the top receiving surface. Electrical contacts of the connector establish electrical communication with the identification chip, providing power to the emitter device and enabling the controller to read data stored in the identification chip.

An example particle accelerator includes a particle source to provide particles to a magnetic cavity; circuitry to provide a radio frequency (RF) voltage to the magnetic cavity to accelerate particles from the ionized plasma in orbits in the magnetic cavity, where the RF voltage has a slope that is less when the particles are injected into the magnetic cavity than when the particles are accelerated in the magnetic cavity; and an extraction channel to receive the particles from the magnetic cavity for output as a particle beam from the particle accelerator.

A single non-thermal atmospheric plasma generation device is used to detect and analyze vital fields of a living subject to determine the presence of a condition, such as an illness or injury, and responsively modify characteristics of the plasma to treat, heal, or alleviate the condition. The device includes a capacitance dielectric discharge array of plasma emitters, and a controller having a power supply, a transformer, and circuit components for driving the transformer at a resonant frequency of the plasma emitters to cause the plurality of plasma emitters to ionize surrounding air and produce the non-thermal plasma.
