METHOD AND APPARATUS FOR ELECTROCHEMICAL DEVELOPMENT OF TRACES PRODUCED BY NUCLEAR PARTICLES

摘要

THE INVENTION CONCERNS THE DEVELOPMENT OF NUCLEAR TRACES IN INSULATING MATERIALS. NUCLEAR TRACES FORMED IN AN INSULATING MATERIAL SHEET 1 COATED WITH A THIN METAL LAYER 2 ON ONE IN ITS FACES, BY SUBMITTING THE NON METALLIC FACE TO AN ATTACK BY A LIQUID ELECTROLYTIC REAGENT 5, WHILE THE OTHER FACE IS IN CONTACT WITH AN INSULATING LIQUID 6. A CONSTANT OR VARIABLE ELECTRIC FIELD IS APPLIED ON EACH OTHER OF THE SHEET USING AN ELECTRODE 8 IMMERED IN THE ELECTROLYTIC REAGENT. THE COMBINED CHEMICAL AND ELECTRICAL ACTION INCREASES THE LENGTH OF THE EXISTING TRACES UNTIL THEY COMPLETELY CROSS THE SHEET OF INSULATING MATERIAL, WITHOUT PRODUCING FOR ALL THE SHORT CIRCUITS. / P P APPLICATION TO DOSIMETERS. / P
