SHARC
From tigwiki
The Silicon Highly-segmented Array for Reactions and Coulex (SHARC) is a multi-purpose array for charged-particle detection.
This Wiki site is intended to provide a collaborative authoring environment for documentation on how to use SHARC and should be seen as a supplement to the pages about TIGRESS. It is written for the users, by the users, and is a living document. If you would like to contribute, please see the section on Contributing Content where appropriate content of the Wiki, the Plone document server, and the e-Log is described.

[edit] Introduction
The very compact array (SHARC) is designed to have high spatial resolution, as well as a large solid angle coverage and particle identification of the measured reaction products. The array can furthermore be used in a variety of dynamic ranges in energy, and will thereby address a diverse set of outstanding nuclear physics questions. This combination offers unique capabilities when integrated with the TIGRESS gamma-ray detectors and the post-accelerated beams at the new ISAC-II facility at TRIUMF, Canada. The project is lead from the University of York and funded by a major grant from the UK Science and Technology Facilities Council (STFC).
Two major research programs will gain significantly from the utilisation of SHARC: Reaction studies and Coulomb excitations (Coulex), both of which will be led by UK physicists. In the reaction studies, particular emphasis will be on transfer reactions used as a tool to indirectly probe nuclear reaction rates important for explosive stellar scenarios such as X-ray bursters, novae, and super novae. The Coulex experiments on the other hand will offer unique insight into nuclear structure at the extremes. In these experiments the reduced transition matrix elements ― such as e.g. B(E2) for Coulomb excitation of the 0+ ground state to the first 2+ excited state of neutron rich or neutron deficient even-even nuclei ― will be probed.
The project is carried out by a collaboration of scientists from University of York, University of Birmingham, Daresbury Laboratory, University of Manchester and University of Surrey (UK); Colorado School of Mines and Louisiana State University (USA); and McMaster University, Saint Mary's University, Simon Fraser University, and TRIUMF (Canada).
