Real-time methods for magnetic resonance spectra acquisition

A method for generating an electromagnetic signal of electron Larmor frequency with modulated amplitude, the method comprising:

• placing into a vacuum area a means made of a non-conductive material with hole inside;
• placing a cathode inside said means and configuring it to emit electrons;
• placing an anode inside said means and configuring it to collect electrons;
• placing a secondary coil in the vacuum area and electrically connecting it to said cathode and said anode;
• placing at least one primary coil and electromagnetically connecting it to the secondary coil;
• forming a permanent magnetic held between the cathode and the anode inside said means by using at least one magnet located outside the means;
• placing a reflector configured to reflect modulated electromagnetic waves of electron Larmor frequency generated between the cathode and the anode due to interaction of the electrons emitted by the cathode and said magnetic held;
• placing electrical connections into the vacuum area that connect the cathode, the anode, and the secondary coil;
• and
• feeding an electrical pulse to the primary coil;
• whereby
• placing electrical connections between the cathode, and the anode and the secondary coil into the vacuum area;
• and
• the electrical pulse is transformed into the electron Larmor frequency electromagnetic signal with modulated amplitude.
