Synchrotron-driven spallation sources [PDF]

Proceedings Particle Accelerator Conference, 2002
The use of synchrotrons for pulsed neutron spallation sources is an example of spin-off from the accelerator development prompted by particle physics. The first proposal for an accelerator-driven source with a thermalised neutron facility was in the 1960s (Intense Neutron Generator, ING), but this project was never built.

Twin‐compartment solid–liquid cells for neutron reflectometry

Journal of Applied Crystallography, EarlyView.
We introduce a twin‐compartment solid–liquid cell for neutron reflectometry that divides a single substrate into two independent measurement areas, doubling sample capacity and enabling direct side‐by‐side comparisons. This sample environment also reduces alignment and sample preparation time and has been successfully tested on both vertical and ...

Li I enhancement during a long-duration stellar flare [PDF]

, 1998
We report the possible detection of a Li I 6708 AA line enhancement during an unusual long-duration optical flare in the recently discovered, X-ray/EUV selected, chromospherically active binary 2RE J0743+224.

Spallation Reactions: Calculations [PDF]

, 1976
Current methods for calculating spallation reactions over various energy ranges are described and evaluated. Recent semiempirical fits to existing data will probably yield the most accurate predictions for these reactions in general. However, if the products in question have binding energies appreciably different from their isotopic neighbors and if ...
