Summary of experimental studies at CERN on a positron source using crystal effects / Artru, X ; Baier, V ; Beloborodov, K I ; Bogdanov, A ; Bukin, A ; Burdin, S ; Chehab, R ; Chevallier, M ; Cizeron, R ; Dauvergne, D et al.
New kind of positron sources for future linear colliders, where the converter is a tungsten crystal oriented on the <111> axis, has been studied at CERN in the WA103 experiment. In such sources the photons which create the $e^+ e^-$ pairs result from channeling radiation and coherent bremsstrahlung. [...]

Experimental study of a crystal positron source / Chehab, R ; Cizeron, R ; Sylvia, C ; Baier, V ; Beloborodov, K I ; Bukin, A ; Burdin, S V ; Dimova, T V ; Drozdetsky, A A ; Druzhinin, V P et al.
Tungsten crystals oriented on their <111> axis, were submitted to 6 and 10 GeV electron beams on the SPS-CERN transfer lines. The crystals, 4 and 8 mm thick, used alone or associated to 4 mm thick amorphous disk, were studied as positron sources. [...]

Experiment with a crystal-assisted positron source using 6 and 10 GeV electrons / Artru, X ; Baier, V ; Beloborodov, K I ; Bochek, G L ; Bogdanov, A ; Bozhenok, A ; Bukin, A ; Burdin, S ; Chehab, R ; Chevallier, M et al.
Axially oriented crystals, penetrated by high-energy electrons, are powerful photon sources and, hence, intense positron sources. Such kinds of positron sources have been studied experimentally at CERN, with the tertiary electron beam of the SPS having an energy of 6 and 10 GeV. [...]

Experimental determination of the characteristics of a positron source using channeling : addendum to P309 and request for beam time in 2001 / Chehab, R. (Orsay, LAL) ; Cizeron, R. (Orsay, LAL) ; Sylvia, C. (Orsay, LAL) ; Baier, V. (Novosibirsk, IYF) ; Beloborodov, K. (Novosibirsk, IYF) ; Bukin, A. (Novosibirsk, IYF) ; Burdin, S. (Novosibirsk, IYF) ; Dimova, T. (Novosibirsk, IYF) ; Drozdetskiy, A. (Novosibirsk, IYF) ; Druzhinin, V. (Novosibirsk, IYF) et al.
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.

Radiation-damage study of a monocrystalline tungsten positron converter / Artru, X (Lyon, IPN) ; Kirsch, R (Lyon, IPN) ; Chehab, R (Orsay, LAL) ; Johnson, B (SLAC, SSRL) ; Keppler, P (Stuttgart, Max Planck Inst.) ; Major, J V (Stuttgart, Max Planck Inst.) ; Rinolfi, Louis (CERN) ; Jejcic, A (Orsay, IPN)
The exploitation of the enhancement of positron sources by channeling effects, in particular for Linear Colliders (LC), relies on the long term resistance of the crystal to radiation damage. Such dama ge has been tested on a 0.3 mm thick tungsten monocrystal exposed during 6 months to the 30 Gev incident electron beam of the SLAC Linear Collider (SLC). [...]
