Abstract	We propose to observe a southwestern knot (SW-K) in the Cygnus Loop. The aim isto find first robust evidence for charge exchange (CX) emission from SNRs. Ourcomprehensive SUzaku XIS studies have found a possible sign of CX. However, dueto the lack of the energy resolution of the XIS, we cannot resolve them clearlyand thus cannot exclude other possibilities from their spectra. The SW-K is oneof the brightest and the most compact region among them. Our simulation showsthat the RGS can clearly divide the O Hea and the Ne Hea triplets into threelines. Their forbidden-to-resonance ratios are useful to find conclusiveevidence for the existence of CX emission from the Cygnus Loop. A 100 ksobservation is required for this purpose.

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.
