==Maximum Power Calculation==
 
* <math>PD</math> - Power density (fundamental constant given by a supplier)
* <math>P(W)</math> - Power (W) from power supply
* <math>A(inch^2)</math> - Area of the target
 
------------------------------------------------------------------------------------------------------------
 
<math> PD=\frac{P(W)}{A(inch^2)}</math>  &#8658;   <math>P(W)=PD\cdot A(inch^2)=PD\cdot\frac{\pi d^2}{4}</math>
 
<ul>
<li><p> <b><span style="color: green">d=2" (2-inch target)</span></b> <math>P(W)=3.14\cdot PD</math>  </p></li>
<li><p> <b><span style="color: green">d=3" (3-inch target)</span></b> <math>P(W)=7.065\cdot PD</math>  </p></li>
<li><p> <b><span style="color: green">d=4" (4-inch target)</span></b> <math>P(W)=12.56\cdot PD</math>  </p></li>
<li><p> <b><span style="color: green">d=6" (6-inch target)</span></b> <math>P(W)=28.26\cdot PD</math>  </p></li>
</ul>

Value of the <math>PD</math> is material dependent and can be found on KJLC homepage
