Abstract
We have surveyed nearly 1500 deg2 of the northern galactic plane for rapidly rotating pulsars using the 76-m Lovell telescope. The sampling rate was such that we have nominal sensitivity to detect pulsars with periods as short as 0.6 ms. To overcome the effects of dispersion, scattering and galactic background radiation, the high frequency of 1420 MHz was used to survey the inner galaxy, while lower frequencies of 928 and 610 MHz were used for regions further from the Galactic Centre. PSR 1937 + 21 was detected in the survey, but no new pulsars were discovered. This is consistent with the results of other recent surveys and suggests that rapidly rotating, high-luminosity pulsars are not very common in the galactic disc.Keywords
