Figure 8
The trend line shows the Touschek lifetime for Phase 2, keeping all the other parameters constant. Full circles show the lifetime calculated using the natural horizontal emittance for the different scenarios. The arrow shows the changes from calculations without (filled circle) and with IBS effects (empty circle). While from the IBS effects the horizontal emittance growth leads to a reduction of the lifetime, the energy spread also increases, leading to a net increase in the Touschek lifetime. |
