	The accelerating gradient of superconducting resonators can be enhanced by engineering the thickness of a dirty layer grown at the cavity's rf surface. In this paper the description of the physics behind the accelerating gradient enhancement by meaning of the dirty layer is carried out by solving numerically the the Ginzburg-Landau (GL) equations for the layered system. The calculation shows that the presence of the dirty layer stabilizes the Meissner state up to the lower critical field of the bulk, increasing the maximum accelerating gradient.

The current interest for the next generation linear induction radiography accelerator (LIA) is to generate multiple electron beam pulses with high peak currents.

Simulation studies of multi-pulse LIAs using AMBER [1] and BREAKUP Code [2] are described.

The impact of energy variation and accelerating voltage error on radiograph performance are discussed.
