    Globular clusters are the site of numerous Xray binaries and recycled
    radio pulsars.The observed Xray sources fall into two categories:high
    luminosity sources associated with accreting neutron stars, and low-
    luminosity systems($L < 10^{34.5}\ ergs\ s^{-1}$)that are essentially
    of unknown origin.Speculation as to the nature of these latter system
    s centers around CVs, LMXBs in quiescence, and collections of RS CVn
    stars.  47 Tuc has several low-luminosity sources that,together,yield
    the highest flux of any cluster (by a factor of 8).  We propose to
    utilize Asuka to obtain a good-quality(composite) spectrum of the 47
    Tuc sources to help determine their basic nature. Such an observation
    may be the best chance at understanding these objects short of a
   direct optical identification.
