On the new possibility of pulse accumulation of UCN

Autor: Frank, A. I., Kulin, G. V., Zakharov, M. A.

The paper considers the concept of an ultracold neutron source (UCN) based on the deceleration of very cold neutrons (VCN) by a local decelerating device. As the latter, it is proposed to use a gradient spin flipper. It is shown that in this case, th

Acceleration effect and the possibility of its observation in neutron-optical experiment

Autor: Frank, A. I., Kulin, G. V., Zakharov, M. A., Goryunov, S. V., Cubitt, R.

The development of ideas about the optical phenomenon called the accelerating matter effect led to the hypothesis of the existence of a very general acceleration effect. Its formulation is that the result of the particle interaction with any object m

On the possibility of creating a UCN source on a periodic pulsed reactor

Autor: Frank, A. I., Kulin, G. V., Rebrova, N. V., Zakharov, M. A.

The possibility of creating a UCN source on a periodic pulsed reactor is considered. It is shown that the implementation of the time focusing principle based on non-stationary neutron diffraction and the idea of the UCN trap pulse filling allow creat

Neutron focusing in time and magnification of the time lens

Autor: Frank, A. I.

The relation between the duration of the pulse of the neutron flux generated by the neutron source and the time image of this pulse formed by the time lens is considered. It is shown that the ratio of these magnitudes called "time magnification" depe

Interaction of a wave packet with potential structures moving with acceleration

Autor: Zakharov, M. A., Kulin, G. V., Frank, A. I.

The paper is devoted to a numerical study of the problem of interaction of the wave packet with potential structures moving with constant acceleration. In all the cases considered the result of the interaction is a change in the velocity spectrum. In

Report

Interaction of a wave with an accelerating object and the equivalence principle

Autor: Frank, A. I.

A new look at the so-called effect of an accelerating matter is presented. It was previously stated that the effect is optical in nature and consists in changing the frequency of the wave passing through a refractive sample moving with acceleration.
