ESR-NMR Control Unit (230 V, 50/60 Hz)

Experimental topics that can be studied with the unit include:

• Resonance absorption of a high-frequency oscillating circuit
• Dependence of resonance frequency on magnetic fields
• Resonant line widths
• Electron and proton spin
• Magnetic moment of atomic particles and nuclei
• Determination of nuclear g-factors
• Nuclear-spin tomography
  The ESR/ NMR control unit is used in conjunction with the ESR module (1022705) to investigate electron spin resonance (ESR) in DPPH (diphenyl picryl hydrazyl) and with the NMR module (1022706) to study nuclear magnetic resonance (NMR) in glycerine, polystyrene and Teflon. Resonances can be observed as a result of transitions induced by high frequencies due to changes in an external magnetic field. Reso-nance absorption curves can be viewed using a simple dual-channel oscilloscope. The control console provides control and pow-er-supply voltages for the test probe being used and for the pair of coils. It also provides a suitable signal for an oscilloscope and displays the value of the high-frequency signal in Hertz. The ESR/NMR control unit numbered 1022700 is designed for 230 V/ 50-60 Hz (±10 %) mains voltage supplies, while 1022702 is for 115 V/ 50-60 Hz (±10 %).  Equipment supplied:1 Control console1 Plug-in power supply, 12 V AC (230 V, 50/60 Hz) Technical data:Control consoleProbe input: 4-pin Lemo socketCoil connectors: Sawtooth current source, 0 − 250 mA, 50 ms, pair of co-axial connectorsMagnetic field output: proportional to coil cur-rent, 0 to 1 V, BNC socketSignal output: Resonance signal, 0 to 1V, BNC socketFrequency range: 45 to 75 MHz approx.(ESR)11 to 15 MHz approx.
