121 | Rotation, acceleration, and gravity sensors using quantum-mechanical matter-wave interferometry with neutral atoms and molecules | US113620 | 1987-10-26 | US4874942A | 1989-10-17 | John F. Clauser |
The invention is a neutral atom (and/or molecule) matter-wave interferometer (and/or set of interferometers) that can be used as an inertial sensor with a sensitivity exceeding that of conventional mechanical sensors and multiple circuit optical interferometers (including ring lasers) by many powers of ten. An interferometer in which matter-wave propagation beam paths enclose a finite area will sense rotations via the Sagnac effect. One with the paths displaced from each other will sense acceleration plus gravity. The matter-wave energy and mass dependence of the phase shifts that are due to rotation and acceleration are different. Thus a pair of interferometers with different energies and/or masses can perform simultaneous independent measurements of rotation and acceleration. Interferometers with paths that follow a figure-eight pattern yield a gravitational gradiometer. Laser cooling and slowing of a beam of neutral atoms provides a low energy nearly monochromatic source. One form of the invention comprises a sequence of slits and/or diffraction gratings operation in high order. Gratings consist of slits in a solid material or near-resonant standing-wave laser beams. Path curvature due to acceleration and rotation is canceled by magnetic and/or electric field gradients that produce an effective levitation of slow atoms. A feedback system that maintains an interferometer phase null is employed with its error signal yielding the inertial effect signals. Magnetic fields are used for producing matter-wave phase shifts. One form of detector images the Moire pattern formed in the light emitted from the resonance fluorescence of a standing matter-wave fringe pattern and a standing-wave laser beam. | ||||||
122 | Heat pipe oven molecular beam source | US636769 | 1984-08-01 | US4558218A | 1985-12-10 | Robert E. Drullinger |
A heat pipe oven molecular beam source wherein a hollow porous metal, metalloid or ceramic body with at least one opening is nearly saturated with the working material and heated to just above the melting point of the working material, generating a thin liquid layer of the working material on the internal surface of the body. Material passing the length of the bore of the body without striking a wall will escape and form the beam. Material striking the liquid layer covering the inside of the body will condense and be conveyed by capillary action back to the closed end of the body. | ||||||
123 | Ionization of organic substances on conveyor means in mass spectrometer | US855579 | 1977-11-29 | US4178507A | 1979-12-11 | Curt Brunnee; Jochen Franzen; Stefan Meier |
Organic samples 10 coming from a liquid chromatograph 11 are deposited on a conveyor belt 13 which transports them into a vacuum chamber at the entry end of a mass spectrometer. The samples are ionized directly on the belt by ion bombardment or using a gaseous charge carrier. Ionization is enhanced by applying an oxide layer to the belt, by neutralizing the image force, and by vaporizing alkali atoms on the belt to reduce the ionization potential. | ||||||
124 | Device for generating an atomic cloud | US877657 | 1978-02-14 | US4164654A | 1979-08-14 | Louis R. P. Butler; Hendrik G. C. Human |
This invention relates to a device for generating an atomic cloud, the device having a housing in which is housed a cathode and an anode, and with suitable passages or flow directing members to direct flow of a gas outwardly away from or past the cathode discharge surface, so that when a suitable potential is applied across the anode and the cathode a glow discharge occurs between the anode and the cathode. The flow of gas preferably draws atoms that are ejected from the cathode discharge surface away from the cathode to a region beyond the cathode glow region, thereby to generate an atomic cloud having a low value of inherent radiation. The device is further incorporated with an apparatus for spectro-scopically analyzing a substance by fluorescent techniques. | ||||||
125 | High brightness ion source | US37445773 | 1973-06-28 | US3914655A | 1975-10-21 | DREYFUS RUSSELL WARREN; HODGSON RODNEY TREVOR |
A high brightness ion beam is obtainable by using lasers to excite atoms or molecules from the ground state to an ionized state in increments, rather than in one step. The spectroscopic resonances of the atom or molecule are used so that relatively long wavelength, low power lasers can be used to obtain such ion beam.

A non-resonance photo-neutralizer for negative ion-based neutral beam injectors. The non-resonance photo-neutralizer utilizes a nonresonant photon accumulation, wherein the path of a photon becomes tangled and trapped in a certain space region, i.e., the photon trap. The trap is preferably formed by two smooth mirror surfaces facing each other with at least one of the mirrors being concave. In its simplest form, the trap is elliptical. A confinement region is a region near a family of normals, which are common to both mirror surfaces. The photons with a sufficiently small angle of deviation from the nearest common normal are confined. Depending on specific conditions, the shape of the mirror surface may be one of spherical, elliptical, cylindrical, or toroidal geometry, or a combination thereof. | ||||||

The interrogation system includes a direction controller that periodically alternates a direction of the optical difference beam through the cell during a CPT interrogation stage of each of the sequential clock measurement cycles to drive CPT interrogation of the trapped alkali metal atoms. The system also includes an oscillator system that adjusts a frequency of a local oscillator based on an optical response of the CPT interrogated alkali metal atoms during a state readout stage in each of the sequential clock measurement cycles. |

A substrate bonding apparatus (100) includes a vacuum chamber (200), a surface activation part (610) for activating respective bonding surfaces of a first substrate (301) and a second substrate (302), and stage moving mechanisms (403, 404) for bringing the two bonding surfaces into contact with each other, to thereby bond the substrates (301, 302). In order to activate the bonding surfaces in the vacuum chamber (200), the bonding surfaces are irradiated with a particle beam for activating the bonding surfaces, and concurrently the bonding surfaces are also irradiated with silicon particles. It is thereby possible to increase the bonding strength of the substrates (301, 302). |
