Control Analysis of the TMT Primary Segment Assembly
primary mirror primary segment assembly segment support assembly
2015/5/12
The primary mirror control system (M1CS) stabilizes the 492 segments of the Thirty Meter Telescope primary mirror in
the presence of disturbances. Each Primary Segment Assembly (PSA) has three actua...
Design of a Prototype Primary Mirror Segment Positioning Actuator for the Thirty Meter Telescope
TMT actuator control system
2015/5/12
In order for the Thirty Meter Telescope (TMT) to achieve the required optical performance, each of its 738 primary
mirror segments must be positioned relative to adjacent segments with nanometer-lev...
Development of the Primary Mirror Segment Support Assemblies for the Thirty Meter Telescope
TMT segment mirror support
2015/5/12
This paper describes the studies performed to establish a baseline conceptual design of the Segment Support Assembly (SSA) for the Thirty Meter Telescope (TMT) primary mirror. The SSA uses a combinat...
