A vector polarimeter at MAMI

چکیده
Atomic bremsstrahlung-polarisation correlation between incoming electrons and outgoing photons may allow to design a polarimeter capable of measuring all components of beam polarisation simultaneously. This device can be called a vector polarimeter. It might allow to test theoretical predictions of correlation coefficients between 1 and 3.5 MeV as well as work as a beam diagnostics device. As a first step we have set up a measurement of the helicity transfer to the photon as a function of electron energy based on the Compton absorption method.

Low-Energy Deuteron Polarimeter
We built a Low Energy Deuteron Polarimeter (LDP) which measures the spin-polarization of deuteron beams in the energy range of 25 to 80 keV. The LDP works by measuring azimuthal asymmetries in the D(~ d, n)He reaction at θlab = 90 ◦ and comparing them to analyzing powers. We built this polarimeter for two reasons. Firstly, to crosscheck other polarimeters at KVI (LSP and IBP). Secondly to test ...
متن کاملGASP - Galway Astronomical Stokes Polarimeter
The Galway Astronomical Stokes Polarimeter (GASP) is an ultra-high-speed, full Stokes, astronomical imaging polarimeter based upon a Division of Amplitude Polarimeter. It has been developed to resolve extremely rapid stochastic (∼ms) variations in objects such as optical pulsars, RRATs and magnetic cataclysmic variables. GASP has no moving parts or modulated components, so the complete Stokes v...
متن کاملTarget detection with a liquid-crystal-based passive Stokes polarimeter.
We present an imaging system that measures the polarimetric state of the light coming from each point of a scene. This system, which determines the four components of the Stokes vector at each spatial location, is based on a liquid-crystal polarization modulator, which makes it possible to acquire four-dimensional Stokes parameter images at a standard video rate. We show that using such polarim...
متن کاملAn ambiguity-free determination of JZ in solar active regions
We propose a way to derive a radial electric current density from vector magnetograms that is free of any particular choice of the two possible azimuths for the plane of the sky field. The method is applied to active region data obtained with the Advanced Stokes Polarimeter (ASP). A comparison of this current density with that derived for two particular sets of possible azimuth assignments allo...
متن کاملFast and optimal broad-band Stokes/Mueller polarimeter design by the use of a genetic algorithm.
A fast multichannel Stokes/Mueller polarimeter with no mechanically moving parts has been designed to have close to optimal performance from 430-2000 nm by applying a genetic algorithm. Stokes (Mueller) polarimeters are characterized by their ability to analyze the full Stokes (Mueller) vector (matrix) of the incident light (sample). This ability is characterized by the condition number, κ, whi...
