   Although the globular cluster rotation-powered pulsars are believed
   to be the descendants of LMXBs, the number of LMXB in the globular
   clusters is smaller than what is expected from the number of the
   pulsars by an order of magnitude. It is recently pointed out based on
   ROSAT observations that a part of the dim cluster sources is probably
   LMXBs in low-state. We attempt to classify the dim cluster sources by
   measuring the spectral hardness of them. Also, half of the bright
   cluster sources known are transient. We try to find out similar
   bright new sources from other clusters. For these purpose, we propose
   to observe 5 globular clusters with 20ksec for each.
