### Abstract

Diffraction radiation generated by relativistic particles passing through a slit in a tilted screen is proposed for nondestructive particle beam diagnostics. For ultrarelativistic panicles with the Lorentz factor y≫1, simple relations are derived for the field strength of diffraction radiation from a slit in a tilted perfectly conducting plane. It is shown that the total radiation loss is proportional to y. The effect of the initial beam divergence on the angular distribution pattern of diffraction radiation is pointed out. A principal possibility of determining a beam divergence smaller than y ^{-1} is demonstrated when measuring the angular distribution of radiation with a constant wavelength.
