Target Studies for the FCC-ee Positron Source
/ Alharthi, F (IJCLab, Orsay) ; Bandiera, L (INFN, Ferrara ; Ferrara U.) ; Chaikovska, I (IJCLab, Orsay) ; Chehab, R (IJCLab, Orsay) ; Diefenbach, J (Helmholtz Inst., Mainz) ; Khomyshyn, O (Taras Shevchenko U.) ; Klekots, D (Taras Shevchenko U.) ; Lauth, W (Helmholtz Inst., Mainz) ; Mazzolari, A (INFN, Ferrara ; Ferrara U.) ; Mytrochenko, V (Kharkov, KIPT) et al.
FCC-ee injector study foresees 3.5~nC electron and positron bunches with 200 Hz repetition and 2 bunches per linac pulse at 6~GeV extraction energy. Regarding the possible options of positron production, we retain both of the conventional amorphous target and the hybrid target options. [...]

Design of Photon Masks for the ILC Positron Source
/ Alharbi, Khaled (Hamburg U. ; DESY, Zeuthen ; KACST, Riyadh) ; Alrashdi, Ayash (KACST, Riyadh) ; Moortgat-Pick, Gudrid (Hamburg U.) ; Riemann, Sabine (DESY, Zeuthen) ; Sievers, Peter (CERN) ; Ushakov, Andriy (Hamburg U.)
A long superconducting helical undulator is planned as baseline to produce polarized positrons at the International Linear Collider (ILC). To protect the undulator walls from synchrotron radiation, masks must be inserted along the undulator line. [...]

Positron sources: from conventional to advanced accelerator concepts-based colliders
/ Chaikovska, I. (IJCLab, Orsay) ; Chehab, R. (IJCLab, Orsay) ; Kubytskyi, V. (IJCLab, Orsay) ; Ogur, S. (IJCLab, Orsay) ; Ushakov, A. (IJCLab, Orsay) ; Variola, A. (INFN, Rome) ; Sievers, P. (CERN) ; Musumeci, P. (UCLA) ; Bandiera, L. (INFN, Ferrara) ; Enomoto, Y. (KEK, Tsukuba) et al.
Positron sources are the key elements for the future and current lepton collider projects such as ILC, CLIC, SuperKEKB, FCC-ee, Muon Collider/LEMMA, etc., introducing challenging critical requirements for high intensity and low emittance beams in order to achieve high luminosity. In fact, due to their large production emittance and constraints given by the target thermal load, the main collider parameters such as the peak and average current, the emittances, the damping time, the repetition frequency and consequently the luminosity are determined by the positron beam characteristics.

Radiative Cooled Target for the ILC Polarized Positron Source
/ Ushakov, Andriy (Hamburg U.) ; Dietrich, Felix (DESY, Zeuthen) ; Riemann, Sabine (DESY, Zeuthen) ; Rublack, Tino (DESY, Zeuthen) ; Sievers, Peter (CERN)
The target for the polarized positron source of the future International Linear Collider (ILC) is designed as wheel of 1 m diameter spinning with 2000 revolutions per minute to distribute the heat load. The target system is placed in vacuum since exit windows would not stand the load. [...]
