THP073 | Simulations of Emittance Measurement at CLIC | 2270 |
|
||
A proposal for a CLIC emittance measurement line using laser-wire beam profile monitors is presented. Results of simulations and optimizations are given. Estimates of the impact of beam size as well as statistical and machine-related errors on the measurement accuracy are discussed. | ||
THP076 | Combined Target-collection System for Positron Production in ILC | 2273 |
|
||
Funding: NSF We describe the positron collection system with Lithium lens, while one of the flanges of this lens made on Tungsten, which serves as a target for the photons radiated in a helical undulator by high-energy ILC beam. |

THP078 | Study of a TeV Level Linear Collider Using Short rf Pulse (~20ns) Two Beam Accelerator Concept | 2279 |
|

Funding: Work is supported by DOE SBIR grant under contract No. DE-SC0004320. In a general sense, a high gradient is desirable for a TeV level linear collider design because it can reduce the total linac length. More importantly, the efficiency and the cost to sustain such a gradient should be considered as well in the optimization process of an overall design. We propose a high energy linear collider based on a short rf pulse (~22ns flat top), high gradient (~267MV/m loaded gradient), high frequency (26GHz) dielectric two beam accelerator scheme. This scheme is a modular design and its unique locally repetitive drive beam structure allows a flexible configuration to meet different needs. Major parameters of a conceptual 3-TeV linear collider are presented. This preliminary study shows an efficient (~7% overall ) short pulse collider may be achievable. As the first step, a dielectric based broadband accelerating structure is under development. |
