Parity Violation in Neutron Resonances of Palladium

, 2002
Parity violation in p-wave neutron resonances of the palladium isotopes 104, 105, 106, and 108 has been measured by transmission of a longitudinally polarized neutron beam through a natural palladium target.

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 ...

Spallation neutron source beam current monitor electronics [PDF]

PACS2001. Proceedings of the 2001 Particle Accelerator Conference (Cat. No.01CH37268), 2002
The Spallation Neutron Source (SNS) to be constructed at ORNL is a collaboration of six laboratories. The beam current monitors for SNS will be used to monitor H-minus and H-plus beams ranging from the 15 mA (tune-up in the Front End and Linac) to over 60 A fully accumulated in the Ring.

Slow neutron leakage spectra from spallation neutron sources [PDF]

, 1980
An efficient technique is described for Monte Carlo simulation of neutron beam spectra from target-moderator-reflector assemblies typical of pulsed spallation neutron sources. The technique involves the scoring of the transport-theoretical probability that a neutron will emerge from the moderator surface in the direction of interest, at each collision.
