PI Wins Substantial Hexapod Order from General Dynamics Daughter for ALMA Millimeter Radio Telescope
Feb. 2006 - Physik Instrumente (PI) has been awarded a contract by Vertex Antenna Systems, a daughter of General Dynamics C4 Systems, to provide 25 six-axis hexapod alignment systems and motion controllers. These custom high-precision micropositioning systems will be employed to align the secondary reflectors in 25 twelve-meter telescopes - the North American portion of the Atacama Large Millimeter Array Project (ALMA) radio telescope.
ALMA is an international joint effort to build the world's most sensitive radio telescope, in Chile's Atacama Desert, 16,500 feet above sea level. Eventually, an array of up to 64 antennas will work together as one giant virtual telescope and provide a spatial resolution 10 times higher than the Hubble Space Telescope. After its completion in 2011, the telescope will allow scientists to observe galaxies in their formative stages with unmatched clarity.
PI was chosen as a supplier for the secondary alignment systems, because of its long track record with designing and manufacturing astronomical secondary hexapods, actuators and active optics. In the last two decades, PI piezo-driven tip/tilt systems, actuators or hexapods have been employed in a number of astronomical telescopes, for example in: Hawaii, Chile, South Africa and the Canary Islands.
