Observe normal pulsar, magnetar and MeV pulsar.
Observe rotation powered pulsars in binaries, including the MSP in low mass X-ray binaries; pulsars in high mass X-ray binaries; observe some supernova remnant and pulsar wind nebulae.
Study emission mechanism in magnetosphere by observing normal pulsars, such as the Crab pulsar.
Explore the emission mechanism of magnetar.
Search MeV pulsars utilizing the observations from CsI of HE together with radio, X-ray or Gamma-ray ephermerides.
