Neutron Imaging at Spallation Neutron Sources

Neutron imaging is a powerful method for non-destructive investigations where the high penetration through metals and the high contrast for hydrogenous materials is exploited in particular. The complementary to X-ray studies is a clever alternative in many cases of scientific and industrial applications. Reactor based neutron sources are becoming less available, caused by the shutdown of aged f...

Beam Instrumentation for the Spallation Neutron Source Ring

The Spallation Neutron Source (SNS) will be constructed by a multi-laboratory collaboration with BNL responsible for the transfer lines and ring. [1] The 1 MW beam power necessitates careful monitoring to minimize un-controlled loss. This high beam power will influence the design of the monitors in the high energy beam transport line (HEBT) from linac to ring, in the ring, and in the ring-totar...

Two-phase flow model for energetic proton beam induced pressure waves in mercury target systems in the planned European Spallation Source

Two-phase flow calculations are presented to investigate the thermo-hydraulical effects of the interaction between 300 kJ proton pulses (2 ms long, 1.3 GeV) with a closed mercury loop which can be considered as a model system of the target of the planned European Spallation Source(ESS) facility. The two-fluid model consists of six first-order partial differential equations that present one dime...

The Spallation Target for the Ultra Cold Neutron Source Ucn

A source of ultra cold neutrons, based on the spallation process is under construction at PSI. With the help of a fast kicker the whole ~1 MW proton beam (590 MeV, 2 mA) from the accelerator will be switched onto the UCN spallation target for approximately 8 seconds every 15 minutes. The spallation neutrons are thermalized in a large heavywater moderator at room temperature and further cooled i...
