Pulsed spallation neutron sources [PDF]

Physics Today, 1979
The discovery of the neutron in 1932, which indirectly led to the potentially catastrophic development of nuclear weapons on the one hand and to the beneficial development of nuclear-generated electricity on the other, has had another, less well-known, but scientifically important consequence: the provision of a uniquely sensitive and pervasive tool ...

Implementing bubbly mercury material model (R-P model) in the pulse simulation to predict strain on the Spallation Neutron Source target vessel with gas injection

Results in Physics, 2023
The Spallation Neutron Source (SNS) creates neutrons by striking a liquid mercury target with short pulses of high-energy protons. SNS targets have been operated with helium microbubble gas injection into portions of the flowing mercury since 2017.

Conceptual Design of the Moderator Test Station at the Spallation Neutron Source [PDF]

EPJ Web of Conferences
We describe the Moderator Test Station (MTS), under construction at the Spallation Neutron Source. We will leverage the Beam Test Facility (BTF) at the Spallation Neutron Source to provide a moderator neutronics test stand with which we will verify the ...

Overview of CSNS tantalum cladded tungsten solid Target-1 and Target-2

Nuclear Engineering and Technology, 2022
A solid tungsten target was used at the China Spallation Neutron Source (CSNS) with 100 kW proton beam power. To improve the lifetime, hot isostatic pressing (HIP) process was selected to bond tantalum cladding with tungsten plates.

Shielding around spallation neutron sources.

Journal of Physics: Conference Series, 2006
Spallation neutron sources provide more intense and harder neutron spectrum than nuclear reactors for which a substantial amount of shielding measurements have been performed. Although the main part of the cost for a spallation station is the cost of the shielding, measurements regarding shielding for the high energy neutron region are still very ...

Dose Measurements around Spallation Neutron Sources

HNPS Proceedings, 2008
Neutron dose measurements and calculations around spallation sources are of importance for an appropriate shielding study. Two spallation sources, consisted of Pb target, have been irradiated by high-energy proton beams, delivered by the Nuclotron accelerator (JINR), Dubna.
