CIZA J1358-4750 is one of the near-by early phase major merger clusters ofgalaxies. It has two distinct humps and a bright bridge region in between.With Suzaku temperature jump, XMM snap shot and Chandra images, we detected aMach sim1.4 shock in the bridge, with a narrow 120. wide hump consideredto be the post-shock region between the forward and reverse shocks. Here wepropose a deep ( 90 virgulks) XMM-Newton observation to resolve the temperaturestructure in the post-shock region. Since the shock age is estimated to be asyoung as 70 virgulMyr, which is 1/3 of the electron Coulomb heating timescale tau_{c} , with the temperature distribution resolved in 24. slices, we areable to determine the actual heating timescale to be shorter than 1/8 tau_c .

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
