A compact and highly collimated atomic/molecular beam source
نویسندگان
چکیده
We describe the design, characterization, and application of a simple, highly collimated, compact atomic/molecular beam source. This source is based on segmented capillary constructed using syringe needle. Angular width measurements free molecular flow simulations show that structure effectively suppresses atoms traveling in off-axis directions, resulting narrow Helium having 7 mrad (full half maximum). demonstrate an this by it for monitoring real-time changes surface coverage clean Cu(110) exposed to oxygen measuring specular reflectivity generated

Creating a collimated ultrasound beam in highly attenuating fluids.
We have devised a method, based on a parametric array concept, to create a low-frequency (300-500 kHz) collimated ultrasound beam in fluids highly attenuating to sound. This collimated beam serves as the basis for designing an ultrasound visualization system that can be used in the oil exploration industry for down-hole imaging in drilling fluids. We present the results of two different approac...
متن کاملCompact electron beam ion source with high-TC bulk superconductors
We have developed an electron beam ion source (EBIS) assembling three rings made of high-TC superconductor as a solenoid coil, which enables us to construct a “table-top” EBIS operated at the liquid N2 temperature with a strong magnetic field. Optimizing a pulse field magnetization procedure, the assembly yielded a magnetic field as high as 0.8 T under a persistent mode, which stably lasted mor...
متن کاملOptomechanical Design of Collimated UV Source Module
This paper presents a UV (ultraviolet) lithography apparatus that utilizes an array composed of UV-LED (light emitting diode) collimation modules as a micro-patterning light source for PCB (printed circuit board) fabrication. To provide a uniform (non-uniformity > 90%) and collimated (FWHM < ±2°) exposure area, hexagonal light source modules are disposed in a hexagonal array. Each module is con...
متن کاملA highly-collimated SiO jet in the HH212 protostellar outflow
We mapped the inner 40 ′′ of the HH212 Class 0 outflow in SiO(2–1), SiO(5–4) and continuum using the Plateau de Bure interferometer in its extended configurations. The unprecedented angular resolution (down to 0. 34) allows accurate comparison with a new, deep H2 image obtained at the VLT. The SiO emission is confined to a highly-collimated bipolar jet (width ∼ 0. 35) along the outflow axis. Th...
متن کاملA compact molecular beam machine.
We have developed a compact, low cost, modular, crossed molecular beam machine. The new apparatus utilizes several technological advancements in molecular beams valves, ion detection, and vacuum pumping to reduce the size, cost, and complexity of a molecular beam apparatus. We apply these simplifications to construct a linear molecular beam machine as well as a crossed-atomic and molecular beam...
