      abstract     = {Experiments in JET with the Be/W ITER-like wall show that
                      in pure hydrogen low-confinement mode (L-mode) plasmas the
                      density limit is approximately $20\%$ higher than their
                      corresponding deuterium plasmas. The maximum achievable
                      density in L-mode plasmas is limited by the
                      magnetohydrodynamic stability of the m/n = 2/1 tearing mode.
                      Studies with the edge fluid-neutral Monte-Carlo code package
                      EDGE2D-EIRENE show that the density of hydrogen atoms inside
                      the separatrix is two times lower than for deuterium in
                      plasma conditions preceding the density limit. The
                      difference between the isotopes is caused by the non-linear
                      process at density limit onset which leads to more efficient
                      dissociation and ionization of hydrogen molecules and atoms
                      in hydrogen than in deuterium plasmas at the high-field
                      X-point region at electron temperatures lower than 2 eV. The
                      m/n = 2/1 island size is estimated to be $30\%$ smaller
                      islands for hydrogen than for deuterium cases for equal
                      fuelling conditions and radial transport assumptions.},
