Novel technique of making thin target foil of high density material via rolling method

The conventional rolling method fails to yield good quality thin foils of thicknesses less than ~ 2 mg/cm2 for high density materials with Z ≥ 70 (e.g. gold, lead). A special and improved technique has been developed to obtain such low thickness good quality gold foils by rolling method. Using this technique thin gold foils of thickness in the range of 0.850−2.5 mg/cm2 were obtained in the present work. By making use of alcohol during rolling, foils of thickness ~ 1 mg/cm2 can be obtained in shorter time with less effort.The conventional rolling method fails to yield good quality thin foils of thicknesses less than ~ 2 mg/cm2 for high density materials with Z ≥ 70 (e.g. gold, lead).
