GMT Actuators

Introduction

Production of the air cylinders and single/triple actuators required for the GMT primary mirror test cell are underway at Texas A&M. The first set of 20 air cylinders have been completed and parts for the next 65 are currently being manufactured. In collaboration with the GMT engineering group our lab has developed the assembly and test procedures for each air cylinder as well as integrating the air cylinders into the single or triple actuator castings. After completion the actuators will be shipped to the University of Arizona to be installed in the primary mirror test cell.
