BASIC STUDIES OF THE ELECTRON SPIN ENERGY LEVELS IN A RUBY
CRYSTAL FOR PRODUCING MASER ACTION AT 2623MHz
Electron spin resonance studies on
the energy levels in a Ruby Crystal required for amplifying signals at 2623MHz were
Calculations and measurements on the effect of different orientations
of the magnetic field on the energy level scheme used for three-level maser action were
studied. It was possible to correlate these effects with relaxation mechanisms between
the electron spin energy levels in the crystal.
The microwave frequncy and power required to achieve population inversion was
determined. A superconducting solenoid was designed to replace a water-cooled conventional
copper wire solenoid.
