TECHNIQUES FOR HANDLING PARTICLES OR ELECTROMAGNETIC RADIATION NOT OTHERWISE PROVIDED FOR; IRRADIATION DEVICES; GAMMA- OR X-RAY MICROSCOPES (X-ray technique H05G; plasma technique H05H) [2]

Arrangements for handling radiation or particles, e.g. focusing, moderating (radiation filters G21K 3/00) [2]

using diaphragms, collimators [2]

using variable diaphragms, shutters, choppers [2]

using diffraction, refraction, or reflection, e.g. monochromators (G21K 1/10, G21K 7/00 take precedence) [2]

Deviation, concentration, or focusing of the beam by electric or magnetic means (electron-optical arrangements in electric discharge tubes H01J 29/46) [2]

087

by electrical means [4]

by magnetic means [4]

Scattering devices; Absorbing devices [2]

Resonant absorbers or driving arrangements therefor, e.g. for Mössbauer-effect devices [3]

using charge exchange devices, e.g. for neutralising or changing the sign of the electrical charges of beams (producing or accelerating neutral particle beams H05H 3/00) [3]

using polarising devices, e.g. for obtaining a polarised ion beam [3]

Radiation filters, e.g. X-ray filters [2]

Conversion screens for the conversion of the spatial distribution of X-rays or particle radiation into visible images, e.g. fluoroscopic screens (photographic processes using X-ray intensifiers G03C 5/17; discharge tubes comprising luminescent screens H01J 1/62; cathode ray tubes for X-ray conversion with optical output H01J 31/50) [3]

with beam-forming means [2]

Holders for targets or for objects to be irradiated [2]

with provision for relative movement of beam source and object to be irradiated [3]

Gamma- or X-ray microscopes [2]
