To All - The website has been upgraded. If you have had trouble downloading the program give it another try. Click on http://home.san.rr-dot-com/jcouture/tesla To obtain the most benefit from the program the following steps are recommended. 1. Enter the power transformer data. The output volts, milliamps, etc. The wattage is an output. If you are using a NST with a primary cap that gives resonant charging increase the milliamps which will increase the wattage and spark length. The spark lengths are for random streamers in air. Controlled sparks would be shorter. 2. Design the Secondary Circuit. Enter the secondary Radius and Turns you want to use. The Turns per inch (TPI) for the secondary wire can be found in tables in several publications including my books. Or if you have the wire you can wind a couple inches on a dowel and count the turns. The Wire Size is for record only. The secondary design determines the TC operating frequency. The program automatically tunes the primary circuit to this frequency. 3. Secondary Terminal - This input affects the operating frequency and other parameters of the coil. There is a graph in one of my books that gives the capacitance for spheres and toroids. The books also give equations to calculate these capacitances. This information is also available in other publications. It is important to have this parameter as an input because the sphere/toroid can be used to change the operating frequency and tune the TC system. The graph (free space) capacitance changes slightly when the sphere/toroid is placed on the secondary coil. 4. Design the Primary Circuit - Select the primary capacitor. There are graphs in my books that show recommended capacitor sizes for different input wattages. The number of primary wire turns (output) is calculated by the computer and will depend on the primary capacitor size and the operating frequency. Adjust the Average Radius Rp to give the "Primary to Secondary Clearance" you want in the output. Adjust the Width of Turns (spiral) to give the "center to center wire/tube spacing" you want in the output. The computer will calculate the inside radius and the outside radius of the coil . Note that all of the physical dimensions of the coil affect the number of turns which are coordinated and calculated by the computer. These dimensions are also calculated by the computer to give the proper inductance so the primary circuit will be in tune with the the secondary circuit at the proper operating frequency at all times. 5. You can click the CALCULATE button at any time and the computer will do the calculations necessary and show you the latest outputs for the latest changes. The coil parameters have been carefully selected to give the maximum output information with the minimum input data. The program can be used to check the coils of other coilers when they provide part or all of the data. I would be interested in your comments to improve the program. John H. Couture
