A system and method sorts particles suspended in a fluid. The system includes a transverse flow filter and a microfluidic sorter. The transverse flow filter concentrates the particles in a retained portion of the fluid. The microfluidic sorter sorts the particles and includes a delivery channel and at least one sorting stage. The delivery channel is dimensioned to permit passage of all the particles in the retained fluid from the transverse flow filter. The delivery channel delivers the particles in the retained fluid to a respective input for each sorting stage and exhausts a remainder of both the particles and the retained fluid at a drain output. Each sorting stage has a labyrinth of interconnected passageways dimensioned to permit passage from the respective input to a respective output for the sorting stage of those of the particles smaller than a respective size for the sorting stage.

A pulsed laser deposition system comprising a split ablation target having a first half and a second half, wherein the target contains a film material for deposition on a substrate, and wherein the film material is comprised of a plurality of component elements, the elements varying in volatility, and wherein one half of the split ablation target contains more of the most volatile elements being deposited than the other half, and wherein the split ablation target is rotated about its center. A laser beam is rastered back and forth across the target such that the laser spends more time on one half of the split target than the other half depending on the elemental volatility. The target rotation and laser beam rastering are coordinated simultaneously to vary the elemental composition of the resulting film deposition.

A cavity oscillator comprising: an amplifier operable to provide energy to a local oscillating signal; a superconducting resonant cavity arranged to receive the local oscillating signal and being operable to reflect a portion of the local oscillating signal for use in a feedback circuit, to support an electromagnetic wave related to the local oscillating signal in a desired TM mode, and to output a filtered signal of a desired frequency or frequencies based on the geometry of the cavity; a feedback circuit operable to generate an error signal based on the local oscillating signal and the reflected signal; and a phase shifter arranged operable to adjust the filtered signal based on the error signal to generate an adjusted filtered signal. The amplifier can amplify the adjusted filtered signal.
