Development of Magnetic Field Components for the Polarisation Option of the Neutron Spectrometer FOCUS

L. Holitzner[1], U. Filges[1], J.P. Embs[2], T. Fennell[2], T. Panzner[1]
[1]Laboratory for Developments and Methods, Paul Scherrer Institut, Villigen, Switzerland
[3]Laboratory for Neutron Scattering, Paul Scherrer Institut, Villigen, Switzerland

We show a new, favourable space-saving method to host a neutron polarizer in the iron-containing monochromator shielding of a time-of-flight spectrometer for cold neutrons. In this poster you can learn e.g., how to create a robust, homogeneous, rectangular magnetic field (here realized ... En savoir plus

Modeling of Limestone Calcination Using Joule Heating

R. Kancharla, and M. Ramakrishna
Padmasri Dr. B.V.Raju Institute of Technology
Narsapur
Medak Dist, AP, India

The limestone calcination reaction is endothermic and will proceed only if the partial pressure of CO2 in the gas above the solid surface is less than the decomposition pressure of the CaCO3. As the reaction is endothermic, the conventional process for calcination uses coal firing in ... En savoir plus
