We report the d.tection of aγ-ray bubble spanning at least 100d.g2 in ultra-high energy(UHE)up to a few PeV in the d.rection of the star-forming region Cygnus X,implying the presence super PeVatron(s)accelerating protons to at least 10 PeV.A log-parabola form with the photon ind.xΓ(E)=(2.71±0.02)+(0.11±0.02)×log10(E/10 TeV)is found.fitting the gamma-ray energy spectrum of the bubble *** sources,“hot spots”correlated.with very massive molecular cloud.,and.a q.asi-spherical amorphousγ-ray emitter with a sharp central brightening are observed.in the *** the core of~0.5°,spatially associating with a region containing massive OB association(Cygnus OB2)and.a microq.asar(Cygnus X-3),as well as previously reported.multi-TeV sources,an enhanced.concentration of UHEγ-rays is observed.with 2 photons at energies above 1 *** general feature of the bubble,the morphology,and.the energy spectrum,are reasonably reprod.ced.by the assumption of a particle accelerator in the core,continuously inj.cting protons into the ambient med.um.
