Superconducting UCN Polarizer for a New EDM Spectrometer
A test experiment has shown that the number of ultracold neutrons (UCN) of one polarization state, transmitted through a 100 μm Al foil when placed in a 5 T magnetic field, is greater by 3.8 times. The increased transmission is due to the higher velocity of the UCN passing through the foil.
Depolarization of UCN stored in material traps
Depolarization of ultra-cold neutrons (UCN) stored in material traps was "rst observed. The probability of UCN spin #ip per re#ection depends on the trap material and varies from 7]10~6 (beryllium) to 10~4 (glass). ( 2000 Elsevier Science B.V. All rights reserved.
Rapid Spatially Coupled AVO Inversion
The Bayesian methodology yields a natural framework for many geophysical inverse problem, see e.g. (Tarantola and Valette, 1982; Tarantola, 1987; Duijndam, 1988a; Duijndam, 1988b). The solution of a Bayesian inverse problem is represented by the posterior distribution. From the posterior distribution the best estimate and the corresponding uncertainty can be extracted and a set of plausible solutions can be drawn.
