“…The detail of those arrangements is presented in Ref. [6]. The loading on the target is evaluated by PEDD (Peak Energy Deposition Density in J/g); the W-Re destruction limit is 76 J/g [13], and the safe operating threshold is considered to be 35 J/g [6].…”

“…A simulation with the tracking down to DR (Damping Ring) was made by Y. Seimiya [4], but no beam loading effect was accounted. A new simulation with the beam-loading effect was done by Kuriki and Nagoshi [5,6]. For those simulations, the peak energy deposition density on the target is kept less than 35 J/g [7], which is considered to be a practical limit of the safety operation.…”

ILC is an electron-positron linear collider based on Superconducting linear accelerator. Linear collider is the only solution to realize high energy electron-positron collision beyond the limit of synchrotron radiation energy loss by ring colliders. Beam current of injector of linear colliders is much larger than that of ring colliders because the beam is not reusable. Providing an enough amount of particles, especially positron is a technical issue. In this article, we present a design of electron driven positron source for ILC. After optimizations, the system design is established with an enough technical margin, e.g. avoiding potential damage on the production target.

“…The interdependency of the polarized positron source on the availability of the 125 GeV electron beam has also spurred a parallel effort in the development of a conventional positron sources based on a 6 GeV electron beam [8,9]. This conventional high current source will simplify the commissioning phase of the accelerator providing a reliable source of positrons.…”

“…To mitigate the risks associated with the ILC project, an electron-driven conventional positron source is being developed as a backup system for the positron source. The progress of the electrondriven positron source for the ILC was recently reported including the feasibility studies in terms of the heat&stress of the accelerator components, the positron yield estimate for realistic conditions such as beam loading effect as well as the status of the target system R&D [73]. In such a way, nowadays, the ILC positron source (both undulator-and the electron-driven) remains the most mature positron source proposed for the future collider in terms of pre-design studies and prototyping.…”

A: 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. In this paper, the conventional positron sources and their main properties are explored for giving an indication to the challenges that apply during the design of the advanced accelerator concepts. The photon-driven positron sources as the novel approach proposed, primarily for the future linear colliders, are described highlighting their variety and problematic.
