Automated system for Nuclear Magnetic Resonance probes

In this multidisciplinary work plan we developed an automated system able to control the tuning of the resonant frequency of a tank (RLC) circuit in Nuclear Magnetic Resonance (NMR) probes. Thus, the variable capacitors tuning (CT) and matching (CM) of such a circuit are remotely controlled with the aid of engines (DC motor) via a computer interface quite quickly and very conveniently from the desk. This technical improvement certainly makes a great difference in NMR experiments in the research of complex and advanced materials in Condensed Matter Physics developed at the IFGW-Unicamp.
