The positron source of the International Linear Collider is based on a superconducting helical undulator passed by the high-energy electron beam to generate photons which hit a conversion target. Since the photons are circularly polarized the resulting positron beam is polarized. At ILC250, the full undulator is needed to produce the required number of positrons. To keep the power deposition in the undulator walls below the acceptable limit of 1W/m, photon masks must be inserted in the… 

Energy Deposition due to Secondary Particles in The Helical Undulator Wall at ILC-250GeV

In the future, International Linear Collider (ILC), a helical undulator based polarized positron source is expected to be chosen. A high energy electron beam passes through a superconducting helical

Design of Photon Masks for the ILC Positron Source

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,

Vacuum systems for the ILC helical undulator

The International Linear Collider (ILC) positron source uses a helical undulator to generate polarized photons of ∼10MeV at the first harmonic. Unlike many undulators used in synchrotron radiation

Design of the Photon Collimators for the ILC Positron Helical Undulator.

A number of photon collimators are placed inside the helical undulator to protect the cold surfaces of the vacuum vessel from being hit by the photons and thus achieving the baseline pressure

An Investigation Into the Design of the Helical Undulator for the International Linear Collider Positron Source

Positrons are produced in the International Linear Collider via pair-production when multi-MeV photons are incident on a metallic conversion target. The multi-MeV photons are generated by the main

A short‐period helical wiggler as an improved source of synchrotron radiation

A new kind of wiggler is proposed as an improved source of synchrotron radiation from high‐energy electron storage rings. The electrons are made to travel in a short‐period helix by a transverse

MODELING SYNCHROTRON RADIATION FROM REALISTIC AND IDEAL LONG UNDULATOR SYSTEMS

An analytic description of the synchrotron radiation from electrons with short-period helical trajectories is given by the Kincaid equation [1]. A new code is under development which generates an
