      abstract     = {Neutron damage is a major deciding factor in the
                      commercialisation of a fusion power plant.Neutron damage
                      inflicted on the walls of the reactor during operation,
                      leads to changes in thebehaviour ofmaterials and ultimately
                      decides the life time of the component. Consequently,it is
                      essential that fusion relevant materials are tested under
                      fusion irradiation conditions inorder to qualify them, prior
                      to use. Tungsten is a keymaterial for the plasma facing
                      componentin a fusion reactor, and is located directly in the
                      path of high energy fusion neutrons. Currently,it is not
                      possible to test the change inmaterial behaviour under high
                      energy neutrons as thereexits no high flux fusion neutron
                      source. Moreover, high flux fission reactors are unable tore
                      produce the high energy neutron damage. However, this work
                      demonstrates the use of 30MeV protons to induce fusion
                      relevant neutron damage on tungsten.This work involves the
                      first irradiation of tungsten using high energy protons
                      (30MeV). Acomplete irradiation cycle, including irradiation
                      planning, sample design and manufacturing,polishing,
                      irradiation, the setting up of post irradiation devices and
                      post irradiation investigationwas carried out within the
                      scope of this work. Optimal sample geometry for
                      acceleratorirradiations, which is also directly comparable
                      and compatible with fission reactor irradiations,was
                      manufactured. The sample holder was designed such that
                      in-situ temperaturemeasurements were possible for the first
                      time. Additionally, hot cell and remote handlingconforming,
                      punch and indentation testing have been developed and
                      demonstrated throughthe use of irradiated active samples.},
