Prototyping of the ILC Baseline Positron Target
The ILC positron system uses novel helical undulators to create a powerful
photon beam from the main electron beam. This beam is passed through a titanium
target to convert it into electron-positron pairs. The target is constructed as
a 1 m diameter wheel spinning at 2000 RPM to smear the 1 ms ILC pulse train
over 10 cm. A pulsed flux concentrating magnet is used to increase the positron
capture efficiency. It is cooled to liquid nitrogen temperatures to maximize
the flatness of the magnetic field over the 1 ms ILC pulse train. We report on
prototyping effort on this system.Comment: 7 pages, 9 figures, Proceedings of the International Workshop on
