<p class="MsoNormal"><span lang="EN-US">Dear FLASH users & developers,</span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">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.
</span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">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.
</span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">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.</span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I would appreciate any help. </span></p>
