“…1. The conceptual design of such a target benefits from the analysis done during the design phase of other rotating target projects such as the second target station project SNS [14] or that regarding the German SNQ project [15], and from the experience acquired during the manufacturing of the rotating target flow test stand [16]. This test stand, built and operated within the ESS-Bilbao facilities, simulates the solid rotating design option for the second target station of SNS, within the framework of a collaborative agreement established between the two institutions.…”

The ESS-Bilbao facility, hosted by the University of the Basque Country (UPV/EHU), envisages the operation of a high-current proton accelerator delivering beams with energies up to 50 MeV. The timeaveraged proton current will be 2.25 mA, delivered by 1.5 ms proton pulses with a repetition rate of 20 Hz. This beam will feed a neutron source based upon the Be (p,n) reaction, which will enable the provision of relevant neutron experimentation capabilities. The neutron source baseline concept consists in a rotating beryllium target cooled by water. The target structure will comprise a rotatable disk made of 6061-T6 aluminium alloy holding 20 beryllium plates. Heat dissipation from the target relies upon a distribution of coolant-flow channels. The practical implementation of such a concept is here described with emphasis put on the beryllium plates thermo-mechanical optimization, the chosen coolant distribution system as well as the mechanical behavior of the assembly.

“…Engineering and safety constraints should be considered first. The solid rotating target cooled by cold plates proposed by ESS-Bilbao [18] is an extension of the design proposed for SNS-STS [19]. From a neutronic point of view, the main advantage of this concept is that it allows to maximize the density of the target material.…”

In the course of discussing different target types for their suitability in the European Spallation Source (ESS) one main focus was on neutronics' performance. Diverse concepts have been assessed baselining some preliminary engineering and geometrical details and including some optimization. With the restrictions and resulting uncertainty imposed by the lack of detailed designs optimizations at the time of compiling this paper, the conclusion drawn is basically that there is a little difference in the neutronic yield of the investigated targets. Other criteria like safety, environmental compatibility, reliability and cost will thus dominate the choice of an ESS target.

“…The problem was solved with a technique of tantalum cladding on tungsten using the HIP method [10] because tantalum is highly corrosion resistant and capable of maintaining sufficient ductility even after high proton irradiation of about 10 dpa [11]. Thus, tantalum-clad tungsten has been revalued to be applicable to the rotating solid target for an intense spallation neutron source with MW-class power [4][5][6]. The remaining problem is radiation embrittlement and low ductility at low temperature.…”

“…We have been studying mechanisms of material damage and developing the materials for the spallation neutron sources [1][2][3]. Tungsten is the most promising material of a rotating target receiving MW-class protons to produce intense long-pulsed neutrons for the second target of the SNS (Spallation Neutron Source) project and the CSNS (Chinese Spallation Neutron Source) target [4][5][6]. Although recent metallurgy has produced the tungsten which can endure the radiation doses as high as 23 dpa [7], high toughness of tungsten will be expected in order to receive high power pulsed proton beam of several MW.…”
