MuPAD

MuPAD (Mu-Metal Polarization Analysis Device) is an option for neutron scattering instruments to perform full 3D polarization analysis with polarized neutrons. 3D polarization analysis in magnetic neutron scattering enables us to understand microscopic magnetic features of magnetic samples.

I designed, built and tested MuPAD during my diploma thesis in physics at the Institut Laue Langevin (ILL) in Grenoble, France between October 2003 and September 2004. The title of my diploma thesis is '3D Polarization Analysis in Magnetic Neutron Scattering. This work was supervised by Prof. Peter Böni of the Technical University of Munich (TUM) and Roland Gähler of the ILL. You are free to download a copy of my diploma thesis as a pdf-file here.

Status

The following photos show the recent version of MuPAD that were constructed by my colleague Serguei Klimko (klimko (a t)ill.fr) between October 2004 and September 2005. MuPAD is currently in operation at SINQ at the Paul Scherrer Institut (PSI) in Villigen, Switzerland and the Physics Department E21 at the Technical University Munich, where the latter is associated with the new research reactor FRM-II.

MuPAD installed on the cold triple-axis spectrometer TASP in the SINQ at PSI.

MuPAD installed on the very cold neutron beamline instrument MIRA at the FRM-II in a small angle scattering setup.
