CXC/ACIS Operations

Welcome to our home page. ACIS, the Advanced CCD Imaging Spectrometer, is an instrument built by a team of scientists and engineers from the Massachusetts Institute of Technology's Center for Space Research and the Pennsylvania State University for the Chandra X-Ray Observatory. ACIS shares the Chandra focal plane with the High Resolution Camera. However, what you will find here is contact information and other resources relevant to the Chandra X-ray Observatory Center (CXC) ACIS Operations team members.
