Hi，

Thank you for your great toolbox.

I want to change the light source to X-ray for simulation, but I don't know how to set it up.

The absorption of x-ray can be obtained by the Beer–Lambert law： I=I0*exp(-μpx). where μ is the mass attenuation coefficient[cm2/g], p is the density[g/cm3], x is the radiation path through the absorber[cm], μp is the linear attenuation coefficient[1/cm].

Best，
