Robin Timmis fredpz: it has always worked fine without a function 14:19:22
masladomHi! I was just wondering , is there an easy way how to define a front-tilted Gaussian laser pulse using LaserGaussian2D/LaserGaussian3D?15:31:22
masladomI mean that there is a tilt between the pulse front and direction perpendicular to the Gaussian beam propagation.15:31:52
beck-llrHi ! I'm afraid this is not supported in the "Gaussian" versions of the laser implementations.15:49:32

If you know an analytical expression you can try to define it in Python in the general Laser block, as in the benchmark tst3d_04_laser_wake.py

In seems that phaseZero doesn't change CEP and waveform, it only shifts it along the time-axis.
Hello, then I would try to define the CEP in the generic Laser block, like in the benchmark tst3d_04_laser_wake.py

Ok sure, I will try that, thank you :)

fredpz Robin Timmis I am unable to test it right now, but I suggest to use print() to find out if there are any unexpected things 12:34:38

Robin Timmis Hi there, I wanted to ask a question about the gamma diagnostic, is it just total energy in simulation units since E=\gamma mc^2 06:56:11
fredpzHi, What do you mean by gamma diagnostic?06:57:13
fredpzBTW, for your previous issue, I would like to test it. Do you have a full input file to share?06:57:37
Robin TimmisI mean as an axes for the particle binning diagnostic07:13:01
fredpzthe axes of particle binning diagnostics are always individual particle quantities07:15:39
Robin Timmissorry I meant total energy of the particle07:19:06
Robin Timmishere is the input file for the other issue I had07:19:33
fredpzAh well gamma is indeed the total energy of the particle07:19:55
Robin Timmis and ekin is the kinetic energy = (\gamma -1)mc^2 07:20:18
fredpzyes07:20:24
fredpzthe file is empty :/07:20:51
Robin TimmisOh sorry!07:21:04
fredpz

So

1. You really need to add .copy() otherwise you set all weights to 0!
2. You inverted the role of "beam" and "plasma". You actually can see a plasma. No issue there.

Robin TimmisThanks :)07:40:39
