Beam profile and beam size measuring

Measuring devices of different types for determination of the charged particle beam profile are considered. The operation principle of ionization profilemeter (IP), based on measuring a signal proportional to the secondary electron number produced during beam ionization of the residual gas is described. The IP parameters designed in CERN are given. The IP construction with parallel electric and magnetic fields for electron removal is described. This IP is developed for the Serpukhov accelerator. The structural scheme of electron beam profile measurement in a betatron is given. The method of rapid filming of synchrotron radiation for determination of the beam profile data is described. The operational principle of emission, acoustic and collector profilemeters are described. It is shown that for visual observation of the beam profile is the most suitable material for screens is lithium glass
