Positron source for FCC-ee
/ Chaikovska, Iryna (Orsay, LAL) ; Apyan, Armen (Yerevan Phys. Inst.) ; Chehab, Robert (Orsay, LAL) ; Enomoto, Yoshinori (KEK, Tsukuba) ; Faus-Golfe, Angeles (Orsay, LAL) ; Furukawa, Kazuro (KEK, Tsukuba) ; Han, Yanliang (Orsay, LAL) ; Kamitani, Takuya (KEK, Tsukuba) ; Martyshkin, Pavel (Novosibirsk, IYF) ; Miyahara, Fusashi (KEK, Tsukuba) et al.
The FCC-ee is a high-luminosity, high-precision circular collider to be constructed in a new 100 km tunnel in the Geneva area. The physics case is well established and the FCC-ee operation is foreseen at 91 GeV (Z-pole), 160 GeV (W pair production threshold), 240 GeV (Higgs resonance) and 365 GeV ($t \bar{t}$ threshold).

Experimental Activities on High Intensity Positron Sources Using Channeling
/ Chaikovska, Iryna (Orsay, LAL) ; Artru, Xavier (Lyon, IPN) ; Chehab, Robert (Orsay, LAL) ; Furukawa, Kazuro (KEK, Tsukuba) ; Guler, Hayg (Orsay, LAL) ; Kamitani, Takuya (KEK, Tsukuba) ; Kubytskyi, Viacheslav (Orsay, LAL) ; Miyahara, Fusashi (KEK, Tsukuba) ; Rodin, Volodymyr (Taras Shevchenko U.) ; Satoh, Masanori (KEK, Tsukuba) et al.
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. [...]

Optimization of an hybrid positron source using channeling
/ Chaikovska, I (Orsay, LAL) ; Chehab, R (Orsay, LAL) ; Guler, H (Orsay, LAL) ; Sievers, P (CERN) ; Artru, X (Lyon, IPN) ; Chevallier, M (Lyon, IPN) ; Suwada, T (KEK, Tsukuba) ; Satoh, M (KEK, Tsukuba) ; Kamitani, T (KEK, Tsukuba) ; Furukawa, K (KEK, Tsukuba) et al.
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.
