| 20110290995 | APPARATUS AND METHOD FOR TRAPPING CHARGED PARTICLES AND PERFORMING CONTROLLED INTERACTIONS BETWEEN THEM - An apparatus and a method for trapping charged particles and performing controlled interactions between them are provided. The apparatus includes a substrate and RF electrodes and dedicated DC electrodes arranged on the substrate and configured to generate a trapping potential for trapping the charged particles above the substrate. The RF and dedicated DC electrodes include at least one RF trapping electrode configured to be driven with an RF voltage for contributing to the trapping potential, an array of two or more trapping site DC electrodes configured to be biased with a DC voltage for contributing to the trapping potential, and a first individually drivable RF control electrode arranged between a first pair out of the two or more trapping site DC electrodes. The first RF control electrode is configured to be individually driven by an adjustable RF voltage such that the trapping potential above and between the first pair of trapping site DC electrodes forms separate charged particle traps adapted for trapping charged particles therein if the adjustable RF voltage takes a first value, and forms a charged particle interaction trap adapted for performing controlled interactions between charged particles if the adjustable RF voltage takes a second value. | 12-01-2011 |
| 20100024619 | DEVICE AND METHOD FOR MACHINING A SOLID MATERIAL USING A WATER JET - A method of machining a solid material using a water jet discharging from a nozzle is specified, wherein the water jet contains ice crystals and impacts on the solid material. In this case, a medium which is gaseous under standard conditions is dissolved in water at a mixing stage under pressure (1-150 bar) and is then compressed to 1000-4500 bar and pressed through a nozzle, under conditions which allow the dissolved gaseous medium to bubble out after leaving the nozzle, whereupon the heat of solution is withdrawn from the water and the ice crystals are formed. | 02-04-2010 |
