THE SCHENBERG SPHERICAL ANTENNA: STATUS REPORT |
Here we present a status report of the Schenberg antenna, which started commissioning runs in September 2006 under the full support of FAPESP. In the past year, however, it has gone to a radical upgrading operation, in which we have been installing a 1K pot dilution refrigerator, cabling and amplifiers for nine transducers circuits, and a new suspension and vibration isolation system for the cabling and microstrip antennas. We also have been developing a new set of transducers, microwave oscillators, microstrip antenna pairs, and studying an innovative approach, which could transform Schenberg into a broadband gravitational wave detector. |
