The binding interactions of the small fragments to the target proteins are understood by X-ray crystallography or other physical techniques like NMR (Nuclear Magnetic Resonance). Speed and decreased attrition rates in drug development are some of the ...
[Question from NMRWiki Q&A forum] How do you build an NMR power amplifier?
How do you build an NMR power amplifier?
And how to you match it to the NMR coil?
Basically I'm looking to perform NMR experiments with frequencies in the 500KHZ region. I already have an arbitrary function generator that I can program with the required pulses at that frequency, now I need to amplifier the signal, and deliver the current to a coil.
How do build an amplifier that can drive a lot of current into a coil at that frequency? Do I resonate the coil with a capacitor, and if so, how do I ensure the resulting circuit won't ring, and ruin the pulse sequences?
