Development of ΔE-E telescope ERDA using an ionization chamber for identification of hydrogen isotopes

We are developing a  ΔE-E_res telescope detector for depth profiling of hydrogen isotopes by elastic recoil detection analysis (ERDA). Energy loss (ΔE) was detected by an ionization chamber, and residual energy (E_res) was detected by silicon surface detector (SSD). In previous research, ΔE was detected by a thin 3.7 μm transmission detector. The production of this detector has been, however, discontinued, therefore we propose an ionization chamber as an alternative for ΔE detection.
