Electron transparency, ion transparency and ion feedback of a 3M GEM
نویسندگان
چکیده
We report the first measurements of electron transparency, ion transparency and ion feedback of a mass produced 3M GEM. Our results indicate that a mass produced GEM and a CERN GEM have similar values of these three quantities. r 2004 Elsevier B.V. All rights reserved.

A performance study of the conceptual implementation of the GEM-tracking detector in Monte Carlo simulation
PANDA experiment (antiProton ANnihilation at DArmstadt) is one of the key projects of the future FAIR facilities to investigate the reactions of antiprotons with protons and nuclear targets. experiment is designed to serve as a completely extraordinary physical potential due to exploiting the availability of cold and high-intensity beams of antiprotons. One of the significant parts of the ...
متن کاملSome aspects of the interrelation between corneal hydration and corneal transparency.
Corneal hydration and transparency still present multiple dilemmas to the inquiring investigator. Transparency is best explained by the oriented-lattice theory of Maurice, but, except for partly adequate electron micrographs, there is no objective evidence for the presence of such a lattice. Further, other transparent ocular structures are not constructed in this way. Relative dehydration and h...
متن کاملAn Electrochemical Investigation of Nano Cerium Oxide/Graphene as an Electrode Material for Supercapacitors
In this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. The electrochemical properties of the produced electrode are studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques in 3M NaCl, NaOH, and KOH electrolytes. Scanning electron microscopy (SEM) is used to characterize the mi...
متن کاملThe Effect of Lyophilization on Light Transmission of Amniotic Membrane: A Comparison with Rabbit Cornea
Background & Aims: Amniotic membrane persists for a long time after ocular transplantation (as corneal substitute) and can affect light transmission (transparency). The aim of this study was to evaluate the transparency of amniotic membrane after freeze-drying (lyophilization) and to compare the results with transparency of rabbit cornea. Methods: Transparency of rabbits’ corneas and fresh and ...
متن کاملTransparency of magnetized plasma at the cyclotron frequency.
Electromagnetic radiation is strongly absorbed by a magnetized plasma if the radiation frequency equals the cyclotron frequency of plasma electrons. It is demonstrated that absorption can be completely canceled in the presence of a magnetostatic field of an undulator, or a second radiation beam, resulting in plasma transparency at the cyclotron frequency. This effect is reminiscent of the elect...
