1.2 GeV electron radiation spectra in thick tungsten single crystals and total radiation losses in tungsten, germanium and silicon single crystals
The experimental investigation of radiation energy losses of ultra relativistic electrons in aligned crystals of various atomic number are of great interest for several reasonye
Experimental Determination of the Characteristics of a Positron Source Using Channeling
Numerical simulations and `proof of principle' experiments showed clearly the
interest of using crystals as photon generators dedicated to intense positron
sources for linear colliders. An experimental investigation, using a 10 GeV
secondary electron beam, of the SPS-CERN, impinging on an axially oriented
thick tungsten crystal, has been prepared and operated between May and August
2000. After a short recall on the main features of positron sources using
channeling in oriented crystals, the experimental set-up is described. A
particular emphasis is put on the positron detector made of a drift chamber,
partially immersed in a magnetic field. The enhancement in photon and positron
production in the aligned crystal have been observed in the energy range 5 to
40 GeV, for the incident electrons, in crystals of 4 and 8 mm as in an hybrid
target. The first results concerning this experiment are presented hereafter.Comment: 3 pages, 6 figures, submitted to Linac200
