Variable bandwidth spin echo delay line
Abstract
Abstract A DELAY LINE FOR MICROWAVE FREQUENCY SIGNALS UTILIZING APPARATUS FOR PRODUCING AN ELECTRON SPIN ECHO SIGNAL FROM AN RF INPUT SIGNAL IN CONJUNCTION WITH AN ANISOTROPIC SPIN ECHO SAMPLE SITUATED IN A MAGNETIC FIELD IN ORDER TO OBTAIN A VARIABLE ELECTRON SPIN RESONANT ABSORPTION LINE WIDTH. THIS IS ACCOMPLISHED BY MEANS OF A CRYSTALLINE QUARTZ SPIN ECHO SAMPLE CONFIGURED IN A PLURALITY OF THIN LAYERS OF LAMINATIONS OF A PREDETERMINED THICKNESS WITH MEANS FOR VARYING THE ORIENTATION OF THE SLABS WITH RESPECT TO ONE ANOTHER IN A STATIC, UNIDIRECTIONAL AND SUBSTANTIALLY HOMOGENEOUS MAGNETIC FIELD SO THAT THE CRYSTALLOGRAPHIC AXIS ORIENTATION OF EACH LAYER IS CONTROLLED RELATIVE TO THE DIRECTION OF THE APPLIED MAGNETIC FIELD SO THAT A SPREADING OUT OF THE COMPOSITE ABSORPTION LINE OR NARROWING OF THE LINE CAN BE ACHIEVED BY VARYING THE ALIGNMENT OF THE LAMINATIONS IN A SELECTED MANNER.
