    A technique is suggested for evaluating the distance two defects on the surface of a fluid-cooled laser mirror must be separated before they can be considered independently. The basic ingredient of the correlation is taken from a technique suggested by Max Jakob for steady-state conduction with heat generation in a circumferential fin. Using this technique with concomitant Bessel functions of zero order and first kind, a distribution of temperatures in a circumferential fin at various radii may be evaluated for cylindrical heat generators acting in concert.
