ELECTRON PARAMAGNETIC RESONANCE SPECTROMETRE (VERSIONS) Russian patent published in 2011 - IPC G01R33/60 G01N24/10 

FIELD: physics.

SUBSTANCE: first version of the electron paramagnetic resonance (EPR) spectrometre has a fixed frequency generator (1), a variable frequency generator (11), a first power divider (2), a second power divider (12), a third power divider (13), a channel switch (14), a first mixer (6), a second mixer (15), a low frequency amplifier (16), an oscilloscope (9), a circulator (3), a resonator (4), a magnetic system (5), an output direct current amplifier (7), a recording system (8) an a computer (10). The second version of the EPR spectrometer additionally has a low frequency power amplifier (17) and a frequency multiplier (18).

EFFECT: possibility of visualising settings and easier tuning of frequency of the resonator with a sample at a fixed working frequency of the microwave generator.
