Contribution

It presents potential approaches for cable design and power distribution tailored for vertex detectors in high magnetic field environments.

Findings

Cable material should be minimized to reduce radiation lengths.

Pulsed power enables gas cooling and efficient operation.

Design strategies accommodate 5 T magnetic field constraints.

Abstract

Vertex detector cable requirements are considered within the context of the SiD concept. Cable material should be limited so that the number of radiation lengths represented is consistent with the material budget. In order to take advantage of the proposed accelerator beam structure and allow cooling by flow of dry gas, pulsed power is assumed. Potential approaches to power distribution, cable paths, and cable design for operation in a 5 T magnetic field are described.
