Abstract

The Center for High Angular Resolution Astronomy (CHARA) Array currently consists of 6 telescopes at fixed positions, connected by vacuum pipes to the delay lines. The CHARA Michelson Array Pathfinder (CMAP) project includes two major components: 1) a mobile telescope that can be placed at a number of locations, and 2) a fiber optic relay system to transport light to the beam combining facility. The telescope will be equipped with a custom-built instrument bench with adaptive optics and fiber injection. The light will be transported by optical fibers to the existing CHARA delay lines. In this contribution, we present the progress on the various subsystems needed to integrate the new telescope and beam transport method into the existing CHARA environment. We will also describe our efforts to find internal fringes with the new fibers.
