We construct a class of CFT's which describe space-dependent closed stringtachyon backgrounds, as the IR limit of GLSM's in which the FI-parameter ispromoted to a superfield. Whole process of tachyon condensation is described bya single CFT. We apply this construction to several examples, in which targetspace is deformed drastically, and the dilaton background may vary, as atachyon condenses.Comment: 20 page
