dc.descriptionThe second fastest millisecond pulsar, B1937+21, is one of several pulsars known to emit giant pulses (GPs). GPs are characterized by their huge energy, power-law cumulative energy distribution, and particular longitudes of occurrence. All these characteristics are different from those of regular pulses. Here, we present a study of GPs from our observations of the pulsar B1937+21 with the GBT at 2.1 GHz in both left and right circular polarization with a time resolution of 8 ns. The Mark5 data acquisition system was used for the first time in single-dish observations with the GBT. This allowed us to obtain continuous and uniform recording for 7.5 hours with a data rate of 512 Mbps. As a result, more than 6000 GPs were found above a detection threshold of 200 Jy. We report on instantaneous spectra of GPs, as well as on a comparison with scintillation spectra of regular emission, on the distribution of GP energies, and on polarization properties of GPs.
