electron paramagnetic resonance
microwave spectroscopy in which there is resonant absorption of radiation by a paramagnet
scanning the act of systematically moving a finely focused beam of light or electrons over a surface in order to produce an image of it for analysis or transmission
fluorescence microscopy light microscopy in which the specimen is irradiated at wavelengths that excite fluorochromes
electron accelerator collider that consists of an accelerator that collides electrons and positrons
electron gun the electrode that is the source of electrons in a cathodeay tube or electron microscope, consists of a cathode that emits a stream of electrons and the electrostatic or electromagnetic apparatus that focuses it
electron microscope a microscope that is similar in purpose to a light microscope but achieves much greater resolving power by using a parallel beam of electrons to illuminate the object instead of a beam of light
electron multiplier a vacuum tube that amplifies a flow of electrons
lens electron lens electronic equipment that uses a magnetic or electric field in order to focus a beam of electrons
tube vacuum tube
thermionic vacuum tube
thermionic tube
electron tube
thermionic valve
electronic device consisting of a system of electrodes arranged in an evacuated glass or metal envelope
electron optics the branch of electronics that deals with beams of electrons and their focusing and deflection by magnetic fields
finger scan
finger scanning
biometric identification by automatically scanning a person's fingerprints electronically
iris scanning biometric identification by scanning the iris of the eye, the structure of the iris is very distinctive
retinal scanning biometric identification by scanning the retina of the eye, identification by retinal scanning is complicated by eye movements
electron shell a grouping of electrons surrounding the nucleus of an atom, the chemical properties of an atom are determined by the outermost electron shell
orbit electron orbit the path of an electron around the nucleus of an atom
electron
negatron
an elementary particle with negative charge
free electron electron that is not attached to an atom or ion or molecule but is free to move under the influence of an electric field
valence electron an electron in the outer shell of an atom which can combine with other atoms to form molecules
beam ray electron beam a group of nearly parallel lines of electromagnetic radiation
beta radiation
beta ray
electron radiation
