Scientific paper
A discussion is presented of the prospective design features of the segmented, 10-m diameter optical-IR range telescope which the University of California is planning to build on Mauna Kea, Hawaii, with attention to the performance levels obtained from prototypes. The telescope primary mirror will be formed by 36 actively controlled mirror segments, which will be polished to their desired shape by stressed mirror polishing. The active control system employs displacement sensors at the edges of the mirror segments to determine their positions, which are then adjusted by three displacement actuators/segment. The telescope overall design is described as a Ritchley-Cretien f/1.75-f/15 system. The telescope's dome is highly compact, and rotates on a stationary building in the manner of conventional telescope domes.
