Hydrogen and carbon target preparation for a positive ion accelerator

Abstract

Abstract A detailed description is given of the techniques used to make hydrogen and carbon targets for the Hanford 2 MeV positive ion accelerator. The hydrogen targets were made by adsorbing deuterium or tritium onto either titanium or zirconium. These metals were mounted on their platinum and tantalum backing disks by evaporation or by sintering. Targets ranged in thickness from 200 to 15000 μg per square centimeter with atomic ratios of 1 to 1. Carbon targets were made by mounting carbon on platinum backing disks by evaporation, painting, or cracking. Targets ranged in thickness from 100 to 5000 μg per square centimeter.
