This figure shows the transition from construction to operations through subsystem Fabrication/Integration and Testing (INT), Construction, Assembly, Integration and Verification (CAIV), Science and Operations Commissioning (SOC) and the period of early operations leading to steady-state operations (some acronyms are used to denote different levels of reviews: Pre-Shipment Review (PSR), Site Acceptance Review (SAR), Final Acceptance Review (FAR) and Science Readiness Review (SRR)).
This Figure shows the various activities involved in the maintenance and cleaning of TMT optics, with their duration and the number of personnel allocated. This is a preliminary allocation which will be updated as the workflows are finalized.

Storage of TMT polished roundels A total of five accepted and completed roundels produced by Coherent are stacked at the TMT storage facility in Fremont, CA, June 2021.
The LGSF mounted on the telescope structure will project powerful laser beams into the upper atmosphere of the Earth, creating artificial stars for adaptive optics correction of the atmospheric turbulence.
The Laser Units (each consisting of a Laser Head and Laser Electronics) are installed on the laser platform. A long beam transfer optics enables the laser beams to be relayed to the LGSF Top-End, where they will be formatted and then launched from the laser launch telescope.
