The High Resolution Array is a detector designed to detect and identify light charged particles like protons, deuterium, triton, alpha's and the different isotopes of nuclei with Z<10. These are particles that are produced in nuclear reactions, and by obtaining an accurate measurement of their direction and energy we can learn much about the dynamics of nuclear reactions and the structure of nuclei.

This detector will consist out of an array of 20 telescopes. Each telescope will consist of two Silicon strip detectors and four Thalium doped Cesium Iodide (CsI(Tl)) detectors.

This project is a collaboration between the National Super-conducting Cyclotron Laboratory Michigan State University , The Indiana University department of Chemistry, Washington University in St. Louis, and INFN Milan in Italy.
