This proposal intends to confirm 10 candidate pulsars in a certain dispersion measures (DMs) range. Using new machine learning ranking and image processing methods, we have identified new candidates (with relatively low dispersion measures) in the Parkes Multibeam Pulsar Survey (PMPS) data. The initial processing of the multibeam survey was so successful that relatively low S/N candidates were placed in a "tier 2" category and never followed-up for re-observation. We, therefore, expect that a large number of relatively weak pulsars with S/N ratios around 8 will later be identified as "real" pulsars. We have already shown, with previous observations, that two of our ranked candidates are pulsars that were missed by the previous processing of the survey and wish to carry out confirmation observation of the next ten of our top-ranked candidates. The new discoveries of low-DM pulsars will significantly improve our understanding of the nearby neutron star population, which may generate a gamma-ray background affecting all related experiments. Additionally, it will also improve our knowledge of the completeness of low DM pulsars in existing surveys, and in turn, help improve the design and performance of further pulsar search surveys. In the last round we were allocated 5 hours, but unfortunately, these were canceled because of the NASA Voyager Voyager tracking.
