5. Abstract

We propose a re-analysis of HST archival STIS-MAMA and HSP UV observations of the
Crab pulsar. By correlating these results with our new ground and space-based Crab
data, we can resolve for the first time the important spectral variations through
the pulse from the IR through the X-ray. The UV HST spectroscopy and polarimetry
play a central role in this analysis, since the synchrotron spectrum breaks through
this energy range, providing unique diagnostics of the pulsar machine.
