Unique electron polarimeter analyzing power comparison and precision spin-based energy measurement

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2004
Precision measurements of the relative analyzing powers of five electron beam polarimeters, based on Compton, Møller, and Mott scattering, have been performed using the CEBAF accelerator at the Thomas Jefferson National Accelerator Facility (Jefferson ...

High speed partial Stokes imaging using a ferroelectric liquid crystal modulator [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2008
This paper describes the implementation of an imaging polarimeter using a single ferroelectric liquid crystal light modulator. It provides partial imaging Stokes information at 234 Hz, much faster than polarimeters using nematic light modulators.

Magnetic Field Structure in Relativistic Jets

open access: yesEPJ Web of Conferences, 2013
Relativistic jets are ubiquitous when considering an accreting black hole. Two of the most extreme examples of these systems are blazars and gamma-ray bursts (GRBs), the jets of which are thought to be threaded with a magnetic field of unknown structure.

The Galway astronomical Stokes polarimeter: optical development

open access: yesEPJ Web of Conferences, 2010
The acquisition time of astronomical polarimeters has in the past been restricted to by the use of polarimeters utilizing modulated or rotating components [1].

Fundamental limitations of the polarization purity of x rays

open access: yesAPL Photonics, 2018
For a few years, x-ray polarimeters have been discussed and even used as a key method for the investigation of fundamental physical questions, from quantum electrodynamics to solid state physics. However, the sensitivity of optical instruments is limited.

Derivation of Instrument Requirements for Polarimetry Using Mg, Fe, and Mn Lines between 250 and 290 nm

open access: yesThe Astrophysical Journal, 2023
Judge et al. recently argued that a region of the solar spectrum in the near-UV between about 250 and 290 nm is optimal for studying magnetism in the solar chromosphere, due to an abundance of Mg ii , Fe ii , and Fe i lines that sample various heights in
