摘要: The ALPHA project is an international collaboration, based at CERN, with the experimental goal of performing precision spectroscopic measurements on antihydrogen. As part this endeavor, experiment includes a silicon tracking detector. This detector consists three-layer array modules surrounding antihydrogen trapping region apparatus. Using device, annihilation position can be determined spatial resolution better than 5 mm. Knowledge distribution was critical component in recently successful effort. paper will describe methods used to reconstruct events Particular attention given description background rejection criteria.
