ILC, XFEL and TTF are planning to use
section with a few third harmonic cavities
(3.9GHz) before the bunch compression section
to improve the beam performances. Fer-
milab is developing superconducting third harmonic section, including cavities, couplers, tuners and cryostat. Few
cavities are built and tested. The status of cavity development and test results are presented in the paper.
Collimators for ILC Conversion System
We considered two types of collimators for
A.A. Mikhailichenko (Cornell University, Department of Physics) usage in undulator conversion system of ILC.
In the first, the Pyrolytic graphite is used and
it is installed in front of a target; the second one uses InGa alloy in rotating cylinder. The last one installed in front of
undulator. Collimators allow absorption single train on bunches in ILC and enhace the photon polarization.
Independent Operation of Electron/Positron Wings of ILC

Test of SC Undulator for ILC
A.A. Mikhailichenko (Cornell University, Department of Physics)
This undulator can be used in ILC positron conversion system.
Liquid Metal Target for ILC
We represent a concept of fast feedback system
allowing independent operation of electron-positron
wings of ILC.
We represent details of design and results of
test SC 40cm-long undulator having period
10mm and aperture ∼8 mm allowing K=0.7.
We considered the Hg target for gamma/
A.A. Mikhailichenko (Cornell University, Department of Physics) positron conversion suitable for usage in ILC
project. Positron scheme generation with undulator
allows usage thin Hg jet confined in profiled duct with rectangular cross-section.
