We report the discovery of 44.7 ms pulsations from the X-ray source CXOUJ181335.1-174957 using data obtained with the XMM-Newton Observatory. PSRJ1813-1749 lies near the center of the young radio supernova remnantG12.82-0.02, which overlaps the compact TeV source HESS J1813-178. Thisrotation-powered pulsar is the second most energetic in the Galaxy, with aspin-down luminosity of Edot = (6.8 +/- 2.7)E37 erg/s. In the rotating dipolemodel, the surface dipole magnetic field strength is B_s = (2.7 +/- 0.6)E12 Gand the spin-down age of 3.3-7.5 kyr, consistent with the location in thesmall, shell-type radio remnant. At an assumed distance of 4.7 kpc byassociation with an adjacent young stellar cluster, the efficiency of PSRJ1813-1749 in converting spin-down luminosity to radiation is approx. 0.03% forits 2-10 keV flux, approx. 0.1% for its 20-100 keV INTEGRAL flux, and approx.0.07% for the >200 GeV emission of HESS J1813-178, making it a likely powersource for the latter. The nearby young stellar cluster is possibly thebirthplace of the pulsar progenitor, as well as an additional source of seedphotons for inverse Compton scattering to TeV energies.
