The recent record-setting performance of the Fermilab Tevatron is the culmination of a long series of efforts to optimize the many parameters that go into generating integrated luminosity for the colliding beams experiments. Here we take an analytical approach in an attempt to illustrate the most fundamental aspects of integrating and optimizing luminosity in the Tevatron. Essential features such as weekly integrated luminosity and store length optimization can be quickly analyzed in terms of antiproton stacking rate and observed beam emittance growth rates in the Tevatron. This optimization approach has been used to maximize the integrated luminosity for Run II. We will build up our understanding in two stages. First, we look at the condition where a collider uses two beams with unequal bunch intensities, and where particles are lost from the accelerator only due to collisions. Next, we introduce a beam lifetime which is independent of luminosity (for example, beam growth and subsequent loss due to noise sources) to arrive at a more realistic description.
