      abstract     = {We report the demonstration of a scanning probe coherent
                      diffractive imaging method (also known as ptychographic CDI)
                      using a compact and partially coherent gas–discharge
                      plasma source of extreme ultraviolet (EUV) radiation at a
                      17.3 nm wavelength. Until now, CDI has been mainly carried
                      out with coherent, high-brightness light sources, such as
                      third generation synchrotrons, x-ray free-electron lasers,
                      and high harmonic generation. Here we performed
                      ptychographic lensless imaging of an extended sample using a
                      compact, lab–scale source. The CDI reconstructions were
                      achieved by applying constraint relaxation to the CDI
                      algorithm. Experimental results indicate that our method can
                      handle the low spatial coherence and broadband nature of the
                      EUV illumination, as well as the residual background due to
                      visible light emitted by the gas–discharge source. The
                      ability to conduct ptychographic imaging with lab–scale
                      and partially coherent EUV sources is expected to
                      significantly expand the applications of this powerful CDI
                      method.},
