  1. Draft Proposal for Halo Collimation in ATF2 A. Faus-Golfe, J. Resta Lopez IFIC P. Bambade LAL LC2013 ATF2 Meeting

  2. Motivation and Planning Study of a possible implementation of an halo collimator device for reducing the background in the instrumentation after the IP of ATF2 FFS • Tracking simulation with “realistic hallo” of the possible scenarios of implementing a retractable hallo collimator jaw in the FFS of ATF2 • Betatron collimation (mainly vertical, IPBSM background reduction) • Energy collimation (mainly horizontal, Compton electron diamond detectors) • Halo generation (two Gaussian superimposed, measurements in ATF2 or others accelerators) • If the simulations studies show that such a system is efficient for the background reduction we will present a proposal in next Technical Board. • If the TB approved the proposal we will start the design, construction and implementation of a retractable hallo jaw collimator. Including dedicated measurements after IP and comparison with simulations. These studies will be complemented by a complete analytical and experimental study of the impact of such a device in the FFS of ATF2 from the point of view of the wakefield effect. LC2013 ATF2 Meeting

  3. First results • Tracking simulation with “realistic halo” (two Gaussian superimposed) has been started with MADx to evaluate and compare the particle losses along the ATF2 FFS ( FFS quads, IP, bending after the IP) in the following cases: • With reference cavity (16 mm aperture) • Standard beam pipe (24 mm aperture) • Tapered beam pipe (16 mm aperture) • Compare the effect from the wakefield point of view ( geometrical and resistive analytical kick) with reference cavity and with the tapered beam pipe LC2013 ATF2 Meeting

  4. Status • The team is a collaborative effort between the Instituto de Física Corpuscular (IFIC) and Laboratoire de l’Accélérateur Linéaire (LAL). • The people involved are: • A. Faus-Golfe, J. Resta Lopez and N. Fuster Martinez (PhD) (IFIC) • P. Bambade, S. Wallon and S. Liu (PhD) (LAL) • and KEK for support and advice LC2013 ATF2 Meeting
