چکیده

A full-scale prototype C-band structure for the e+elinear collider has been built in which the dipole powers are damped to suppress the long-range transverse wakefield. To verify that the damping works as expected, the C-band structure was tested in the Accelerator Structure SETup (ASSET) at SLAC. This paper presents results of the wakefield measurement with ASSET.

Studies of Beam Induced Dipole-Mode Signals in Accelerating Structures at the SLC

Beam emittance dilution by self induced transverse elds (wake elds) in accelerating structures is a key problem in linear accelerators. To minimize the wake eld e ects the beam trajectory must be precisely centered within the structures. An e cient way to achieve this is to detect beam induced microwave signals in the lowest dipole mode band and to steer the beam by minimizing these signals. Th...

Damping Effect Studies for X-band Normal Conducting High Gradient Standing Wave Structures*

The Multi-TeV colliders should have the capability to accelerate low emittance beam with high rf efficiency, X-band normal conducting high gradient accelerating structure is one of the promising candidate. However, the long range transverse wake field which can cause beam emittance dilution is one of the critical issues. We examined effectiveness of dipole mode damping in three kinds of X-band,...

Detection of Beam Induced Dipole-Mode Signals in the SLC S-Band Structures*

Beam emittance dilution caused by wakefield effects is one of the important issues in the SLC linac. The detection of beam induced dipole mode signals in the C.. band range could provide a direct measure of the strength of transverse wakefield kicks the beam experiences in the accelerating structures. We investigate the applicability of these microwave signals for beam steering purposes. The RF...

Optimized Wakefield Suppression & Emittance Dilution-imposed Alignment Tolerances in X-band Accelerating Structures for the Jlc/nlc

In order to prevent electrical breakdown occurring in the JLC/NLC (Japanese Linear Collider/Next Linear Collider) X-band structures several new structures are under investigation. These accelerating structures represent an evolutionary design of the DDS series of structures [1]. The phase advance per cell has been varied and the detailed elliptical shape of the cell has been varied in order to ...

Beam Loading and Higher-band Longitudinal Wakes in High Phase Advance Traveling Wave Accelerator Structures for the Glc/nlc

A multi-bunch beam, traversing travelling wave accelerator structures, each with a 5π/6 phase advance per cell, is accelerated at a frequency that is synchronous with the fundamental mode frequency. As per design, the main interaction occurs at the working frequency of 11.424 GHz. However, modes with frequencies surrounding the dominant accelerating mode are also excited and these give rise to ...
