Figure 7
Transverse phase space at the radiator, immediately after laser interaction (black dots), after two turns (blue dots), after three turns (red dots). From top to bottom: whole beam, only particles at ΔE/E > 0.4% (p-factor > 5), only particles at ΔE/E > 0.4% and within 1 ps time window centred on the laser interaction region. |
