AWAKE Simulations

Poster Simulation 09-09-22

Simulation of short driver bunches. Beams are defined directly within the configuration and beamfiles run through lem.py for diagnostics.


Run Number Base Configuration Window Width Window Length q/m Total Weight (pC) LCODE ampl LCODE Beam Current LCODE Beam Length Beam Length (um) Energy (approx) (GeV) Comments
1 short_bunch - DAC 3 10 1.0 -2045.504558 1 -3.6 0.1 3.63 30 Default DAC short_bunch.cfg
2 short_bunch - DAC 3 10 0.00054 -2045.504558 1 -3.6 0.1 3.64 30 Only change made to cfg m/q for protons. Ez plots for 1 and 2 are identical.
3 short_bunch - DAC 3 20 1.0 -2045.504558 1 -3.6 0.1 3.64 30 Plot x-range increases with window length increase.
4 short_bunch - DAC 3 100 1.0 -2045.504558 1 -3.6 0.1 3.63 30 Expecting Ez fall off with distance. Do observe this.
5 short_bunch - DAC 3 100 0.00054 -2045.504558 1 -3.6 0.1 3.64 30 Checking to see if Ez attenuation with distance is different for q/m=1/1836 (proton ). Identical plots.
6 short_bunch - DAC 3 20 0.00054 -2045.504558 -1 -3.6 0.1 3.64 30 Can compare this with run 3 as mass not impacting currently. Identical despite ampl=-1 meaning should be opposite charge. Will set this directly in m/q next.
7 short_bunch - DAC 3 20 1.0 total weight 1 -3.6 0.1 length 30 Despite setting m/q=1 in cfg, lem still shows positive and so results identical to run 3.
