R&D; for positron sources at high-energy lepton colliders
/ Moortgat-Pick, Gudrid (Hamburg U. ; DESY) ; Riemann, Sabine (DESY, Zeuthen) ; Sievers, Peter (CERN) ; Tenholt, Carmen (DESY)
Several designs for high-energy Lepton Colliders serving as Higgs factories but extendable to higher energies up to the TeV range are under discussion. The most mature design is the International Linear Collider (ILC), but also the Compact Linear Collider (CLIC) as well as the new concept of a Hybrid Asymmetric Linear Higgs Factory (HALHF) have a large physics potential.

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. [...]

Proposal for the ILC Preparatory Laboratory (Pre-lab)
/ International Linear Collider International Development Team Collaboration
During the preparatory phase of the International Linear Collider (ILC) project, all technical development and engineering design needed for the start of ILC construction must be completed, in parallel with intergovernmental discussion of governance and sharing of responsibilities and cost. [...]

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).

Studies of a scheme for low emittance muon beam production from positrons on target
/ Collamati, Francesco (INFN, Rome) ; Antonelli, Mario (Frascati) ; Boscolo, Manuela (Frascati) ; Biagini, Marica (Frascati) ; Blanco-Garcia, Oscar (Frascati) ; Variola, Alessandro (Frascati) ; Bacci, Alberto (INFN, Milan) ; Liuzzo, Simone (ESRF, Grenoble) ; Raimondi, Pantaleo (ESRF, Grenoble) ; Chaikovska, Iryna (Orsay, LAL) et al.
A new scheme to produce muon beams characterised by very low emittance, in such a way to avoid the need for cooling, using a positron beam of about 45 GeV interacting on electrons on target is being studied by our group. This scheme is challenging and innovative, and needs a full design study to be developed. [...]
