Recent additions to Kassiopeia also allow it to simulate neutral particle trajectories in magnetic fields based on their magnetic moments. Two different methods were implemented: an exact method that can work for arbitrary fields and an adiabatic method that is limited to slowly-varying fields but is much faster for large precession frequencies. Additional interactions to simulate reflection of ultracold neutrons from material walls and to allow spin-flip pulses were also added. These tools were used to simulate neutron precession in the Paul Scherrer Institute's neutron electric dipole moment experiment and predict the values of the longitudinal and transverse relax- ation times as well as the trapping lifetime.

Facilities and Methods Ultracold Neutrons—Physics and Production
facilities and methods Ultracold Neutrons—Physics and Production Introduction Free neutrons are the most funda- mental ones of the easily accessible, electrically neutral spin-1/2 systems. They take part in all the four known interactions: they strongly interact with nucleons and nuclear matter, they undergo weak β-decay, they have magnetic moments and gravitational mass. Although the neutron itself is a composite system, and thus, strictly speaking, not a fundamental particle, it is one of the finest probes for funda- mental physics. Neutrons can be and are used to study all interactions, to search for new interactions, to test fundamental quantum mechanics and symmetries of nature. Over the past five decades the field of slow neutron Figure 1.

The truly high density that could be obtained at TRIUMF would allow a class of precision measurements to be conducted with signiﬁcantly improved statistical and systematic uncertainties, and thus more signiﬁcant results. This source would therefore make a major impact on studies of fundamental physics with UCN that would complement and enhance the ISAC program. A window of opportunity exists to capitalize on the successes of Y. Masuda’s group at KEK and at RCNP, thereby allowing the TRIUMF project to surpass other proposed sources elsewhere.

Neutron Phase Spin Echo
PHYSICAL REVIEW C 93, 045501 (2016) Neutron phase spin echo Florian M. Piegsa,1,* Patrick Hautle,2 and Christian Schanzer3 1ETH Zurich,¨ Institute for Particle Physics, CH-8093 Zurich,¨ Switzerland 2Paul Scherrer Institute, CH-5232 Villigen PSI, Switzerland 3SwissNeutronics AG, CH-5313 Klingnau, Switzerland (Received 25 January 2016; revised manuscript received 11 February 2016; published 8 April 2016) A novel neutron spin resonance technique is presented based on the well-known neutron spin echo method. In a first proof-of-principle measurement using a monochromatic neutron beam, it is demonstrated that relative velocity changes of down to a precision of 4 × 10−7 can be resolved, corresponding to an energy resolution of better than 3 neV. Currently, the sensitivity is only limited by counting statistics and not by systematic effects. An improvement by another two orders of magnitude can be achieved with a dedicated setup, allowing energy resolutions in the 10 peV regime. The new technique is ideally suited for investigations in the field of precision fundamental neutron physics, but will also be beneficial in scattering applications.

The possibility of relatively fast neutron oscillations into a mirror neutron state is not excluded experimentally when a mirror magnetic field is considered. Direct searches for the disappearance of neutrons into mirror neutrons in a controlled magnetic field have previously been performed using ultracold neutrons, with some anomalous results reported. We describe a technique using cold neutrons to perform a disappearance and regeneration search, which would allow us to unambiguously identify a possible oscillation signal. An experiment using the existing General Purpose-Small Angle Neutron Scattering instrument at the High Flux Isotope Reactor at Oak Ridge National Laboratory will have the sensitivity to fully explore the parameter space of prior ultracold neutron searches and confirm or refute previous claims of observation. This instrument can also conclusively test the validity of recently suggested oscillation-based explanations for the neutron lifetime anomaly. 1 Introduction that can resolve the ambiguity associated with the source of ultracold neutron losses [14, 15]. The astrophysical evidence for dark matter is strong.

Golub Hahn Meitner Institut, 14109 Berlin, Germany Ultracold neutrons, that is, neutrons whose energy is so low that they can be contained for long periods of time in material and magnetic bottles, provide the basis for the currently most sensitive experiments seeking to detect the neutron electric dipole moment and to measure the neutron lifetime.

Experiments with Ultracold Neutrons
Experiments with ultracold neutrons - first 50 years. Yu.N. Pokotilovski1 Joint Institute for Nuclear Research 141980 Dubna, Moscow region, Russia Abstract This year is 50 anniversary of the first experimental observation of ultracold neutrons (UCN). I present my reminiscences of the first experiment in Dubna, first encounter with F.L. Shapiro – pioneer of the UCN investigations, and the early stage of the UCN experiments. Present status of investigations with UCN is shortly reviewed. PACS: 28.20.-v; 29.25.Dz; 14.20.Dh; 13.30.-a. Keywords: ultracold neutrons. 1 Prologue. My 1968 before UCN. 1968 was the last year of my postgraduate studentship in Moscow academic Institute. The topic of my work was the experimental study of interactions of high energy protons with big (quasi-infinite) uranium targets - so called electronuclear method of generation of neutrons and fuel isotopes. The experimental part was performed at the JINR synchrocyclotron and consisted in the measurement of production of neutrons and 239Pu in big uranium targets of different depletion and different central proton beam targets, bombarded by protons in the energy range 300-660 MeV. At that time this method was considered as a possible radical alternative to the arXiv:1805.05292v1 [physics.hist-ph] 14 May 2018 breeder-reactor-plus-fuel-reprocessing industry and as a way to solve the future world energy problem due to involvement of all uranium to energy production without en- richment process. Later, when it became clear that situation with mineral sources of energy is not as sad as was predicted, this theme was put aside.
