From systematic analysis of the high pulsed magnetic field resistance data of La2−x Srx CuO4 thin films, we extract an experimental phase diagram for several doping values ranging from the very underdoped to the very overdoped regimes. Our analy- sis highlights a competition between charge density waves and superconductivity which is ubiquitous between x = 0.08 and x = 0.19 and produces the previously observed double step transition. When suppressed by a strong magnetic field, superconductivity is resilient for two specific doping ranges centered around respectively x ≈ 0.09 and x ≈ 0.19 and the characteristic temperature for the onset of the competing charge den- sity wave phase is found to vanish above x = 0.19. At x = 1/8 the two phases are found to coexist exactly at zero magnetic field.
