Method of controlling placement of micro-objects

Disclosed are methods and systems of controlling the placement of micro-objects on the surface of a micro-assembler. Control patterns may be used to cause phototransistors or electrodes of the micro-assembler to generate dielectrophoretic (DEP) and electrophoretic (EP) forces which may be used to manipulate, move, position, or orient one or more micro-objects on the surface of the micro-assembler.

Stimulated X-ray emission source with crystalline resonance cavity
11031745 · 2021-06-08 ·

An X-ray laser has a target anode of a crystalline material that emits X-ray radiation in response to excitation and that is located on a thermally conductive substrate. An X-ray source provides an input X-ray beam that illuminates a predetermined volume of the target anode at a predefined angle relative to a surface of the anode so as to induce a Borrmann mode standing wave in the predetermined volume. An electron source outputs an electron beam that is incident on the Borrmann mode region so as to cause electron impact ionization of the crystalline material and thereby induce stimulated emission of a coherent output X-ray beam.
