Abstract

Abstract

The background of Thirty Meter Telescope(TMT) and its mission that we should take in hand are introdced. The detailed specifications and the preliminary scheme for the M3CA and M3PA in the 3 mirror(M3) system are presented according to the general specification. Then, the two parts,axial support and lateral support of M3CA, are designed in detail. Due to the kinematic concept design used in both of axial support and lateral support, the mirror surface error can be reduced in a acceptable level. When the kinematic axial support scheme is taken, its surface accuracy RMS is 109.7 nm and Slope RMS is 0.95 rad, while the kinematic lateral support scheme is taken, its surface accuracy RMS is 15 nm,and the first natural frequency can reach to 17.7 Hz. The design proposal for M3PA is discussed and the control system for M3 system(M3CS) is introduced briefly.
