     "Bragg edge imaging is a neutron imaging technique used to study the crystalline structure of materials.\n",
-    "It relies on the phenomenon where neutron transmission through a polycrystalline sample drops sharply at specific wavelengths, known as Bragg edges.\n",

     "These edges correspond to the constructive interference condition for different crystallographic planes within the material.\n",
     "This technique is particularly useful for characterizing strain, texture, and phase composition in engineering materials and other polycrystalline systems.\n",
