Abstract
The Applied Technology Group at TRIUMF operates three accelerators, TR30-1, TR30-2 and CP42 that use 30 MeV proton beams in the generation of commercial radioisotopes. These cyclotrons typically use diamond-like carbon (DLC) stripper foils produced in house of between 2.0 and 3.0 lm to extract particle beams from these cyclotrons. Micromatter (formerly the TRIUMF Carbon Foil Laboratory) manufactures DLC foils in a range of thicknesses from 10 nm to *10 lm using pulsed laser deposition. Continuing our previous work '(Zeisler and Jaggi Nucl Instrum Methods Phys Res A 613:434, 2010)' we further investigated the presence of boron in multilayer DLC foils, specifically DLC/boron/DLC hybrid foils. In this work, we investigated the mechanical properties and lifetime of these stripper foils in cyclotrons with varying thicknesses and boron content as well as a special DLC layer deposited by chemical vapor deposition and find an improvement in flexibility, mechanical strength and lifetime.
