Search for gravitational radiation from the Crab pulsar

The result of a revised search for the gravitational radiation from the Crab pulsar at 60.2 Hz is presented. Cold damping was applied to a 1400-kg aluminum quadrupole antenna at room temperature. The resulting antenna system had a bandwidth increased to 0.012 Hz and a noise temperature reduced to 24 K. From the taped record of 621 h of observation, we have obtained an upper limit for the energy flux of the radiation in one of the polarization components: $S_{G+}<0.08\mathrm{}$ ${\mathrm{W}/\mathrm{m}}^2$.
