Group of TECI graduate students, postdoctoral researchers, and early-career professionals from partners in the Thirty Meter Telescope International Observatory visiting TMT Lab on 6 December 2018 during the annual TECI workshop. The workshop is designed to support international collaboration among the TMT partners including Caltech, Canada, China, India, Japan, and University of California. A full week program to build community among TMT future users and leaders, and connect them to current TMT leaders.

TMT member NAOJ with their industrial partners Canon Inc. and SHIBA R&D CO. Ltd. successfully performed hexagonal cutting of a full size primary mirror segment. Metrology measurements carried out by Coordinate Measurement Machines (CMM) show that critical dimensions of parts including pockets for sensors and actuators, meet TMT stringent requirements.

Dewars of liquid nitrogen (LN2) installed on the two Nasmyth platforms provide each TMT instrument’s cooling needs and maintain a steady state of cooling for all instruments. The total wet mass (including full cryogen load) of the CRYO components on each Nasmyth platform shall be less than 3,000 kg.

Engineers from TMT project office were happy to welcome TMT International Observatory (TIO) Board Members at their technical laboratory near Pasadena. The visit was organized over the course of TIO Board of Directors meeting on Tuesday 31 July 2018. This was a unique opportunity to present the multi segment integration and test facility that will be used to verify and test all TMT primary mirror system components and assemblies prior to full-scale production. TIO Board Members are pictured in front of the primary mirror cell prototype that will host seven full size segments to verify the performance and operation of the primary mirror control system.

Glen Cole, TMT lead optical fabrication engineer, explains the technical steps involved in the integration of the glass segment with the new segment support design, prior to carrying out the optical test validation. The assembly tool is seen in the background. TIO Board members are looking over the safety perimeter of the spherical segment, which is guarded under a piece of protective black foam.

Alastair Heptonstall, TMT opto-mechanical engineer, is testing the guide flexure of the M1 segment to measure the component stiffness. Each TMT individual segment must be controlled to create a continuous M1 mirror. TMT control system can move segments individually and the guide flexures allow the segments to move while resisting lateral motions. This test is part of the performance assessment to ensure the control system can align the mirror to achieve the required telescope performance.
