to a minimum when the flipping takes place. We are now able to flip the 3He gas inside a standard “magic box” with a loss of polarisation of about 10-5 per flip. If the flipper is activated once a minute ... Axial Vector Coupling λ=gA/gV from a Measurement of the β-Asymmetry Parameter A in Neutron Beta Decay D. Mund, B. Märkisch, M. Deissenroth, J. ...

Capelli at work on CYCLOPS. A general view By june 2009, CYCLOPS recorded its first Laue patterns. Less than 5 seconds were enough to get excellent data from a ruby crystal of a few mm 3 in size.
