THPMN028 | Development of the Strip-line Kicker System for ILC Damping Ring | 2772 |
|
||
The performance of the kicker system for the International Linear collider(ILC) is the one of the key component to determine the damping ring(DR) circumference and the train structure. The parameters are discussing at the baseline configuration design for the ILC. The bunch trains in the linac are 2820(5640) bunches with 308(154) ns spacing and the repetition rate is 5Hz. The bunch spacing in the DR is 6(3) ns. The kicker has to have fast rise and fall times of 6(3) ns and the repetition rate of 3.25(6.5) MHz. The development work of the kicker system using multiple strip-lines is carried out at KEK-ATF. The beam test result of the single unit is described. Also Experimental results on new scheme to improve the rise and fall times will be presented. | ||
THPMS013 | Comparison of Tracking Codes for the International Linear Collider | 3020 |

Funding: Supported by the US Department of Energy, the US National Science Foundation and the Commission of the European Communities under the 6th Framework Programme "Structuring the European Research Area". In an effort to compare beam dynamics and create a benchmark'' for Dispersion Free Steering (DFS) a comparison was made between different International Linear Collider (ILC) simulation programs while performing DFS. This study consisted of three parts. First, a simple betatron oscillation was tracked through each code. Secondly, a set of component misalignments and corrector settings generated from one program was read into the other to confirm similar emittance dilution. Thirdly, given the same set of component misalignments DFS was performed independently in each program and the resulting emittance dilution was compared. Performance was found to agree exceptionally well in all three studies. |

THOAC01 | ATF Extraction Line Laser-Wire System | 2636 |
|
||
Funding: PPARC LC-ABD Collaboration Royal Society Daiwa Foundation Commission of European Communities under the 6th Framework Programme Structuring the European Research Area, contract number RIDS-011899 The ATF extraction line laser-wire (LW) aims to achieve a micron-scale laser spot size and to verify that micron-scale beam profile measurements can be performed at the International Linear Collider beam delivery system. Recent upgrades to the LW system are presented together with recent results including the first use of the LW as a beam diagnostic tool. |

THPMS056 | Emittance Preservation in the International Linear Collider Ring to Main Linac Transfer Line | 3118 |
|

Funding: Work supported by the US Department of Energy, contract DE-AC02-76SF00515. The very small vertical beam emittance in the International Linear Collider (ILC) can be degraded by dispersion, xy coupling, transverse wakefields, and time-varying transverse fields introduced by elements with misalignments, strength errors, xy rotation errors, or yz rotation errors in the Ring to Main Linac (RTML) transfer line. We present a plan for emittance preservation in this beamline which uses local, quasi-local, and global correction schemes. Results of simulations of the emittance preservation algorithm are also presented and discussed. |
