The positron source under investigation is using channeling radiation of multi-GeV electrons in a tungsten crystal. The radiated photons are impinging on the amorphous targets creating e⁺e⁻ pairs. [...]

The hybrid positron source made of a crystal-radiator, as a source of channeling radiation, and an amorphous converter is briefly described. Optimization of the heating effects and thermal shocks led to a granular converter made of small tungsten spheres. [...]

Investigations on a hybrid positron source with a granular converter
/ Artru, X (Lyon, IPN) ; Chaikovska, I (Orsay, LAL) ; Chehab, R (Lyon, IPN) ; Chevallier, M (Lyon, IPN) ; Dadoun, O (Orsay, LAL) ; Furukawa, K (KEK, Tsukuba) ; Guler, H (Orsay, LAL) ; Kamitani, T (KEK, Tsukuba) ; Miyahara, F (KEK, Tsukuba) ; Satoh, M (KEK, Tsukuba) et al.
Promising results obtained with crystal targets for positron production led to the elaboration of a hybrid source made of an axially oriented tungsten crystal, as a radiator, and an amorphous tungsten converter. If the converter is granular, made of small spheres, the heat dissipation is greatly enhanced and the thermal shocks reduced, allowing the consideration of such device for the future linear colliders.

High Energy Phys.) ; Strakhovenko, Vladimir M (Novosibirsk, IYF) ; Variola, Alessandro (Orsay, LAL ; Orsay)
A non-conventional positron source using the intense l radiation from an axially oriented monocrystal which materializes into e(+)e(-') pairs in a granular amorphous converter is described. The enhancement of photon radiation by multi-GeV electrons crossing a tungsten crystal along its <111> axis is reported. [...]
