HESS J1702-420 is a PeVatron candidate without multi-wavelength associations.The identification of active PeVatrons, CR accelerators reaching the knee (few10^15 eV), is key to understand the origin of CRs in the Galaxy. With deepobservations and improved analysis, H.E.S.S. has recently found a new compactsource, hidden under the bulk emission of HESS J1702-420. Its straight and veryhard powerlaw spectrum, extending up to 100 TeV, makes it a very solid PeVatroncandidate. Remarkably, Suzaku has detected, with large uncertainties, an X-raysource very close to the new compact TeV source. These facts, together with thediscovery of energy-dependent shrinking of HESS J1702-420 towards the new TeVsource, call for a deep XMM observation to investigate a PWN scenario.

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.
