A team of researchers from the University of California and Caltech are investigating the feasibility of building a 30 meter diameter segmented mirror telescope, following the design approach pioneered by the 36-segment Keck telescopes. The current design concept for the California Extremely Large Telescope (CELT) has 1080 segments forming the primary(More)
The design of transmitter masts is determined by the wind load. The mast should sustain the load without excessive stresses but moreover in order to prevent malfunctioning of the antennae, the rotation at the top has to be limited. Because the time dependent character of the wind, the response is inherent dynamic and susceptible to resonance effects. The(More)
