Large area multiturn superfluid phase slip gyroscope

چکیده
We have built and tested a large area multiturn superfluid He phase slip gyroscope. This device demonstrates quantum-mechanical phase coherence of superfluid He over a macroscopic length scale ~1.4 m!. The sensing loop area of this device is two orders of magnitude larger than our proof-of-principle model, with an improvement in sensitivity of ;20 over any other superfluid He gyroscope. We find that this rotation sensor has excellent long-term stability. In addition, there are no new noise sources preventing further enhancements in sensitivity. © 2003 American Institute of Physics. @DOI: 10.1063/1.1536727#

RMP Colloquia The role of the Josephson-Anderson equation in superfluid helium*
This article explains how a simple equation describing the time evolution of a superfluid’s quantum phase can be used as a powerful tool to rapidly deduce exact magnitudes of physical observables in situations involving very complex vortex motion. The equation has been used to simplify the understanding of new phenomena, such as vortex precession. Applications of the equation have also led to s...
متن کاملVISCOSITY COEFFICIENTS OF THE A-PHASE OF SUPERFLUID He AT LOW TEMPERATURES
It has been shown that the Boltzmann equation for the viscosity of the A-phase of superfluid 3He at low temperatures has the same form as for a normal Ferrni liquid. The viscosity coefficients A, B, C, D and E are derived exactly. The h , parameter plays an important role in determining the temperature dependence of the viscosity coefficients
متن کاملPhase-slip memory effects in dissipation-free superflow
Critical superflow, preceding a free ringing superfluid oscillation, induces a remnant stochastic uncertainty in the oscillation amplitude. We demonstrate that the distribution function for the oscillation’s velocity amplitude reflects both the quantized size of the underlying phase-slip dissipation events, as well as the stochastic nature of the processes which nucleate the slips @S0163-1829~9...
متن کاملNovel method for multiturn extraction: trapping charged particles in islands of phase space.
A novel method for multiturn extraction from a circular particle accelerator is presented, based on trapping particles into islands of phase space generated by nonlinear resonances. By appropriate use of sextupoles and octupoles, stable islands can be created at small amplitude in phase space. By varying the linear tune, particles can be trapped inside these islands and then transported towards...
متن کاملCritical Flow of Superfluid Helium-4 through a Submicron Aperture: Width of the Critical Transition
1. EXPERIMENT We-have observed that the critical velocity of the _ flow of superfluid 4He through a submicron aperture exhibits fluctuations which increase with temperature. We have analyzed these fluctuations in order to gain information about the velocity dependence of the probability of occurrence of dissipative phase-slip events. These measurements were made with the same apparatus and duri...
