Abstract

For many years there has been an aspiration within the community to develop curved silicon detectors for particle physics applications. We present the results from 10 × 10cm low mass support modules as a part of the “ZeroMass” project that aims to minimise the material budget for tracking and vertexing systems for future colliders. We use

50 μ m

thick DC coupled strip sensors from Micron Semiconductor Ltd., with a carbon composite support frame. Our current module demonstrators use a radius of curvature of 15 cm, typical of that used for the outer parts of large pixel systems, or the inner part of strip trackers and the outer part of large radii vertex detectors. The material budget obtained varies from an

X_{0}

of 0.05% in the active area to 0.62% in the support structure, with an average of 0.28%. There is further scope for material budget reduction in applying the concept and methods to large instruments for future detector systems, which we also discuss.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
