Transcranial Magnetic Stimulation (TMS) is a technique to stimulate brain tissue directly through the skull. It works by sending a very high current pulse through a coil that is located on the subject's scalp. The fast-rising edge of the pulse induces a current in the brain tissue, causing neuron stimulation.
This device uses a capacitor bank, high current SCR, trigger circuit, figure-8 (or butterfly) coil, and high voltage charging circuit.

Ha! I found a complete TMS system at the local university surplus auction. I didn't buy it, however.
great work. Where did you get the SCR and how much did you pay for it.
The SCR was donated by a generous person. I don't know what it is worth.
