Description
The designs for both the International Linear Collider (ILC) and the Compact LInear Collider (CLIC) envisage the need for of order 10^14 positrons per second, two orders of magnitude greater than the rates delivered at the Stanford Linear Collider (SLC). This extrapolation requires novel technologies to keep the stresses placed on the conversion targets to manageable levels. At the same time, it has been recognised that it is highly-desirable to be able to deliver both polarised electrons and polarised positrons to the interaction point(s) of the colliders in order to maximise the physics reach of the machines.
Here I present the status of the two leading technologies for generating intense beams of polarised positrons: helical undulator insertion devices and laser Compton scattering techniques, with emphasis on work carried out by the HeLiCal collaboration in developing the baseline positron source for the ILC.
