Target Design Challenges
Contributed Focus Session Oral Presentation
High energy physics experiments often require a target to produce subatomic particles of scientific interest. In a typical particle accelerator, a high energy particle beam is fired at the target and the interaction results in the emission of neutrons or other particles of interest which in the case of charged particles are often refocused with magnetic fields. Many existing and proposed...

Target Design Challenges
Contributed Focus Session Oral Presentation
The Facility for Rare Isotope Beams (FRIB) under construction at Michigan State University is based on a 400 kW heavy ion accelerator and uses in-flight production and separation to generate rare isotope beams. The first section of the fragment separator houses the rare isotope production target and a primary beam dump to absorb unreacted primary beam. FRIB will use ion beams from 18O to 238U...

Target Design Challenges
Contributed Focus Session Oral Presentation
CERN is presently operating various particle producing targets and the associated infrastructure in its accelerator complex, including a neutron spallation source, an antiproton production targets, a neutrino target and various general-purpose primary targets for test beams and experiments. At the same time, devices of different types and characterized by high power density as well as high...

Target Design Challenges
Contributed Focus Session Oral Presentation
A detailed thermal and mechanical analysis was carried out for the spallation target of the ISIS 2nd target station (TS2). The objective was to develop a better understanding of operating conditions in the target and to identify factors limiting target lifetime.
The TS2 target consists of a solid tungsten rod, with tantalum cladding to improve corrosion resistance. The cladding is bonded to...

The ESS spallation target will be operating at 5 MW proton beam power. As the 5 MJ/s proton beam power is concentrated in 2.86 ms long 14 Hz pulses, the instantaneous power during each pulse impinging on target reaches 125 MJ/s. This large pulsed power condition poses a challenge in designing a robust and reliable target without sacrificing much of the neutronic performances.
In this...

Target Design Challenges
Contributed Focus Session Oral Presentation
The performance of a spallation neutron source depends on the underlying physics, its engineering and available technologies. However, the realization of a project and the operation of the facility will – in the real world - depend on the financial resources and political support. Funding will only be granted if appropriate sales arguments are given. A fashionable argument is to deliver a high...
