[FLASH-USERS] How to set a dual pulse simultaneously irradiated on a disc target to generate a colliding plasma

[Wu, Yaoxing]

Dear FLASH users & developers,

I am doing some simulations of laser produced plasma. I have a question about how to set a dual pulse simultaneously irradiated on a disc target to generate a colliding plasma.

I edit and add another Gaussian Beam2 in the runtime parameter file (.par) copied from LaserSlab simulation. The distance between Beam 1 and Beam 2 is set to 1000 um.

All laser parameters of Beam 1 and Beam 2 are same except the incident position. But the plasma parameters generated by two beams are not same. I have attached the .par file and the electron temperature at 8 ns (The ray trace in the picture is 0 ns). I also attached my experimental setup which I want to simulate.

I would appreciate any help.

Thanks!

Regards,
