  Our Chandra X-ray observation of the globular cluster 47 Tuc clearly detected
most of the 16 MSPs with precise radio positions, and indicates probable X-ray
emission from the remainder. The MSPs are soft (BB kT 0.2-0.3 keV) and faint
(Lx few 10^{30} ergs/s), and generally consistent with thermal emission from
small polar caps. An additional 40 soft X-ray sources are consistent with the
known MSPs in X-ray colors, luminosity, and radial distribution within the
cluster (and thus mass). We note that these MSPs display a flatter Lx to Edot
relation than pulsars and MSPs in the field, consistent with polar cap heating
models for younger MSPs and may suggest the surface magnetic field has been
modified by repeated accretion episodes to include multipole components.
Correlating HST images, radio timing positions, and the Chandra dataset has
allowed optical searches for MSP binary companions. The MSP 47 Tuc-U is
coincident with a blue star exhibiting sinusoidal variations that agree in
period and phase with the heated face of the WD companion. Another blue
variable star (and X-ray source) agrees in period and phase with the companion
to 47 Tuc-W (which lacks an accurate timing position); this companion is
probably a main sequence star.
