Abstract: A time-of-flight mass spectrometer having a chamber with electrodes to generate an electric field in the chamber and electric gating for allowing ions with a predetermined mass and velocity into the electric field. The design uses a row of very thin parallel aligned wires that are pulsed in sequence so the ion can pass through the gap of two parallel plates, which are biased to prevent passage of the ion. This design by itself can provide a high mass resolution capability and a very precise start pulse for an ion mass spectrometer. Furthermore, the ion will only pass through the chamber if it is within a wire diameter of the first wire when it is pulsed and has the right speed so it is near all other wires when they are pulsed.

Assume an instance where an electromagnetic wave showing a comb-shaped spectrum having a plurality of narrow bands as indicated by P1 through P14 and tuning with excitation energies corresponding to the rotational levels of molecule X is irradiated onto the molecule X. The molecule X can sequentially make transitions to higher energy levels by using an electromagnetic wave showing such a comb-shaped spectrum. The energy levels of molecule Y are not synchronized with the comb-shaped spectrum. The two ranges of Y4 through Y7 and Y12 through Y15 operate as gates and the molecule Y cannot make transition from a rotational level to another when a gate is found between them.

Abstract: In a scan measurement in which a mass scan is repeated across a predetermined mass range, when a voltage is returned from a termination voltage of one scan to an initiation voltage for the next scan, an undershoot or other drawbacks occur to destabilize the voltage value. Therefore, an appropriate waiting time is required. Conventionally, this waiting time has been set to be constant regardless of the analysis conditions. On the other hand, in the quadrupole mass spectrometer according to the present invention, the mass difference ?M between the scan termination mass and the scan initiation mass is computed based on the specified mass range, and a different settling time is set in accordance with this mass difference. When the mass difference ?M is small and hence requires only a short voltage stabilization time, a relatively short settling time is set. This shortens the cycle period of the mass scan, which increases the temporal resolution.

Abstract: As sample sizes have decreased to microscopic levels, it has become desirable to establish a method for thin film processing and observation with a high level of positional accuracy, especially for materials which are vulnerable to electron beam irradiation. The technological problem is to judge a point at which to end FIB processing and perform control so that the portion to be observed ends up in a central portion of the thin film. The present invention enables display of structure in cross-section by setting a strip-like processing region in an inclined portion of a sample cross-section and enlarging the display of the strip-like processing region on a processing monitor in a short-side direction. It is then possible to check the cross-sectional structure without additional use of an electron beam. Since it is possible to check the processed section without using an electron beam, electron beam-generated damage or deformation to the processed section is avoided.

An image may be created by averaging arithmetically at least one frame obtained by the first scan and at least one frame obtained by the second scan.

Abstract: A method and apparatus are disclosed for high-sensitivity Single-Photon Emission Computed Tomography (SPECT), and Positron Emission Tomography (PET). The apparatus includes a two-dimensional (2D) gamma detector array that, unlike a conventional SPECT machine, moves to different positions in a three-dimensional (3D) volume space near an emission source and records a data vector g which is a measure of gamma emission field. In particular, the 3D volume space in which emission data g is measured extends substantially along a radial direction r pointing away from the emission source, and unlike a conventional SPECT machine, each photon detector element in the 2D gamma detector array is provided with a very large collimator aperture. Data g is related to the 3D spatial density distribution f of the emission source, noise vector n, and a system matrix H of the SPECT/PET apparatus through the linear system of equations g=Hf+n. This equation is solved for f by a method that reduces the effect of noise.

Abstract: A method and system for nuclear imaging normally involve detection of energy by producing at most two or three bursts of photons at a time in response to events including incident gamma radiation. F number of sharing central groups of seven photodetectors, depending on the photodetector array size, is arranged in a honeycomb array for viewing zones of up to F bursts of optical photons at a time for each continuous detector and converting the bursts of optical photons into signal outputs, where each of the central groups is associated with a zone. This enables the detector sensitivity to be increased by as much as two orders of magnitude, and to exchange some of this excess sensitivity to achieve spatial resolution comparable to those in CT and MRI, which would be unprecedented. Signal outputs that are due to scattered incident radiation are rejected for each of the central groups to reduce image blurring, thereby further improving image quality.
