The routine for the processing of a stack consisting of 117 K-5 pellicles 15 cm x20 cm x 1200 Vm in size is described in detail. Measurements of the lateral shrinkage of the processed pellicles indicate absence of irregular deformations. A multiple scattering calibration on K/sup -/ tracks contained in the stack (715 Mev/c momentum) yields, without corrections, an accurate p BETA value in agreement with the known p BETA of the beam. Blob countings on beam tracks show a high degree of uniformity of development throughout the entire depth of the pellicles, a high plateau blob density and good discriminating properties of the emulsion. It is concluded that the qualities of freeprocessed 1200 mu m pellicles are, to all effects, equivalent to those of standard glass- backed emulsions. This enables one to take full advantage, otherwise generally precluded, of the use of such thick pellicles. (auth)
