Mode decomposition refers to a set of techniques aimed recover modal content in multimode optical fibers. In this Letter, we examine the appropriateness similarity metrics commonly used experiments on mode few-mode We show that conventional Pearson correlation coefficient is often misleading and should not be as sole criterion for justifying performance experiment. consider several alternatives propose another metric most accurately reflects discrepancy between complex coefficients, given...
We consider the capability of flexible spin-transparent polarization control and manipulation in conventional synchrotrons at integer spin resonances by means navigators. The latter are designed as a couple small solenoids separated constant beam bend. formulate requirements to navigator design considering criteria for stability motion presence synchrotron energy oscillations. propose novel spin-flipping system free resonant depolarization based on such navigator. discuss possibilities...
Abstract In this paper we propose a lattice insertion for the Nuclotron ring called “spin navigator” that can adjust any direction of proton polarization in orbital plane using weak solenoids. The control is realized spin transparency mode at energy 108 MeV, which corresponds to integer resonance γ G = 2. requirements on navigator solenoid fields are specified considering criteria stability motion during manipulation an experiment. presents results numerical modeling dynamics operated mode....
We propose an alternative approach to compensation of intermodal interactions in few-mode optical fibers by means digital backpropagation. Instead solving the inverse generalized multimode nonlinear Schrödinger equation, we accomplish backpropagation signals with help their near-field intensity distributions captured a camera. demonstrate that this task can successfully be handled deep neural network and provide proof concept training autoencoder for six linearly polarized (LP) modes...
Abstract Hadron polarization control schemes for Spin Transparent (ST) synchrotrons are analyzed. The spin dynamics and beam in such controlled by navigators (SN) which special small insertions of weak magnetic fields. An SN stabilizes the allows setting any desirable orientation at an interaction point operational regime, including a frequent flip. We present general approach to design SNs. distinguish different types SNs, namely, those not causing closed orbit perturbation as well...
A spin navigator based on correcting dipoles has been proposed to manipulate the directions of protons spins in experiments at Nuclotron synchrotron (JINR, Dubna). The polarization is controlled by means controllable distortion beam closed orbit dipoles, which ensures significant enhancement action particles. method measure coherent effect lattice imperfection dynamics navigator. An idea a compensator presented, allows one eliminate polarization. and make it possible perform series verify...
