Smooth solid DT layers inside a spherical shell are needed in order to achieve ignition on the Laser MegaJoule (LMJ) facility. This paper presents a few novel techniques developed in our lab to achieve the required temperature and surface roughness conditions. Results are presented that confirm our hypotheses and lead us to be confident that we may achieve the requirements for the cryogenic LMJ ignition target.
