Figure 7
IBS and microwave instability effects calculated as a function of single-bunch current for Phase 2 with 3HC (triangles) and without 3HC (circles and diamonds). Top plots are horizontal and vertical emittances and lower plots are bunch length and energy spread. Red plots include IBS only and green ones also include microwave growth rate. Note that for the case with 3HC the longitudinal plane is stable due to the very long bunches. |
