  1. Flat Beam Generation Via beam shaping: Elliptical beam distribution: y Larmor rotation b x a YAG3 Virtual Cathode

  2. Optimization values for the AWA parameters (Flat Beam) For laser pulse of 1.15 ps (Q = 100pc)

  3. Larmor angle = -18 degrees  need to rotate beam on the Virtual cathode by 18 degrees to compensate for the rotation effect( get rid of coupling) when we generate the initial particle distribution. Define parameter e such that: Correlation

  4. Track of Twiss parameters : Track of R parameter : R = SC effects /emittance effects Come from the envelope equation Emittance Ratio =

  5. Density distribution at VC Density distribution at YAG3 e = 1 e = 1/2 e = 1/10 e = 1/50 e = 1/100

  6. Blue: Red: Angle in degrees Emittance dominant [31,17,10,4,1]

  7. g = gap width = 0.0508m Enge coefficients for Dipole B profile (version 17)

  8. c coefficients: *using fmin search* c = 0.4656 -2.6516 -1.2879 -0.2804 0.0237 -0.1952 -0.1405 -0.0242 *using polyfit* c = 0.4876 -2.8936 -1.5224 -0.1953 0.2725 0.0660 -0.0183 -0.0050 Note: c = c_i where i = 1,…,8

  9. AWA Emittance Exchange (round beam) For laser pulse of 1.15 ps (Q = 100pc)

  10. Some Simulation results
