Submitted for the DAMOP15 Meeting of The American Physical Society Coincidence electron/ion imaging with a fast frame camera WEN LI, SUK KYOUNG LEE, YUN FEI LIN, STEVEN LINGENFELTER, ALEXANDER WINNEY, LIN FAN, Wayne State University — A new timeand positionsensitive particle detection system based on a fast frame CMOS camera is developed for coincidence electron/ion imaging. The system is compo...

An imaging photoelectron photoion coincidence spectrometer at the vacuum ultraviolet (VUV) beamline of the Swiss Light Source is presented and a few initial measurements are reported. Monochromatic synchrotron VUV radiation ionizes the cooled or thermal gas-phase sample. Photoelectrons are velocity focused, with better than 1 meV resolution for threshold electrons, and also act as start signal ...

PET scanners based on LSO have the potential for significantly better coincidence timing resolution than the 6 ns FWHM typically achieved with BGO. This study analyzes the performance enhancements made possible by improved timing as a function of the coincidence time resolution. If 500 ps FWHM coincidence timing resolution can be achieved in a complete PET camera, the following four benefits ca...

Using the field ion microscope as a flow reactor the catalytic oxidation of hydrogen by O2 on Pt has been studied by the ToF coincidence technique. The "imaging ions" consist mainly of H30+. less H20+ and to some extent field and coverage sensitive 02+ species. The product ion spectrum qualitatively coincides with that of pure water field desorbed at 300 K. On the oxygen side of the H2/02/Pt sy...

OBJECTIVE To assess the usefulness of dual-head camera imaging with 2-[fluorine-18]fluoro-2-deoxy-D-glucose (FDG) in the identification of malignant pancreatic lesions. MATERIAL AND METHODS Fifteen (15) patients with pancreatic masses (7 females and 8 males, mean age 52 10 years) have been studied prospectively. After a 12-hour fasting patients received 120 MBq of FDG and were imaged in a dua...

In this paper, by applying the countable extensions of a t-norm, we have proved a coincidence point theorem for the fuzzy Nadler type of contraction mappings. Also, a coincidence point theorem in a fuzzy metric spaces for an implicit relation is given.

The classical theorems in projective geometry involve constructions based on points and straight lines. A general feature of these theorems is that a surprising coincidence awaits the reader who makes the construction. A classical example of this is Pappus’s theorem. One starts with 6 points, 3 of which are contained on one line and 3 of which are contained on another. Drawing the additional li...

In this paper we obtain new inclusion and coincidence theorems for absolutely or multiple summing multilinear mappings. In particular, we derive optimal coincidence theorems of Bohnenblust-Hille type for multilinear forms on K-convex Banach spaces of cotype 2.
