Description The properties of the inner gaps have been subject to theoretical debate. X-ray
observations of the sub-pulse drifting pulsars open a door to greatly constrain
the properties of the inner gaps from the data. A previous XMM observation of
PSR B0943+10 by the PI has provided strong evidence of the existence of a
partially screened inner gap in this pulsar. In order to definitely test the
theory, an observation of another sub-pulse drifting radio pulsar with higher
significance is desirable. PSR B0826-34 is an ideal target to achieve this goal.
We propose a 50 ks exposure of this pulsar to detect the X-ray emission due to
polar cap heating and to differentiate a thermal spectrum from a power law one.
This has profound implications for the understanding of pulsar inner gaps.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
