WEPMN041 | Reduction of RF Skin Loss with Thin Foils | 2134 |
|
||
Reduction of RF power loss caused by skin effect has been studied. Some measurement results on a coaxial cavity with thin foils are described. Application to another type of RF devices will be discussed. | ||
THPMN006 | Modification and Measurement of the Adjustable Permanent Magnet Quadrupole for the Final Focus in a Linear Collider | 2719 |

Funding: This research was partially supported by JSPS, Grant-in-Aid for Scientific Research, 14204023-2002, 18204023-2006 and the U. S. DOE under contract DE-AC02-76SF00515. An adjustable permanent magnet quadrupole has been developed for the final focus in an electron-positron linear collider. The design has two concentric rings of permanent magnets. Recent activities include a newly fabricated inner ring that demonstrates the strongest field gradient at a small bore diameter of 15mm and a new magnetic field measurement system based on a rotating coil. The prospects of the R&D will be discussed. |
