Debye-Scherrer Cylindrical Powder Camera The Plan View

3 Debye-Scherrer Cylindrical Powder Camera The Plan View 

measuring 25 from film which is loaded on the inside wall and knowing R the radius of the camera and the wavelength A, we can calculate the inter planar spacing dhki for the hkl plane. The dhki for the cubic system is related to the lattice parameter a by 

By using Debye-Scherrer technique for polycrystals, lattice parameter can be determined. The lines (arcs) can be indexed by adopting the following
