Methods and devices for mixing a first fluid with a second fluid downhole include a chamber having a first end, a second end and an opening for fluid to flow there through. A top surface of a perforated piston is capable of contacting the second end and a top surface of a piston is capable of contacting a bottom surface of the perforated piston. The perforated piston is located at a first position within the chamber based upon characteristics of a first fluid. A first fluid delivery system supplies the first fluid and a second fluid delivery system supplies a second fluid to the chamber, wherein the second fluid is at a pressure that moves the piston approximate to the first end. An actuating device applies a force against the bottom surface of the piston to inject the fluids through channels of the perforated piston to produce spray droplets.

A betatron structure having a donut-shaped vacuum chamber, wherein the vacuum chamber is made up of two or more pieces bonded together; an injector positioned within the vacuum chamber; and two or more magnets positioned to the outside of the vacuum chamber. A method of manufacturing a betatron structure, including: (a) fabricating two or more pieces; (b) positioning an injector on one of the two or more pieces; and (c) bonding the two or more pieces such that when bonded, the substrates form a hollow donut-shaped chamber.
