In order to avoid the optical noise we let the whole path of the laser beam be within black-walled cylindrical tubes until it entered the photodetector . This has eliminated the optical noise to about zero. To avoid the entrance of scattered light ...

Rutherford backscattering spectrometry
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.
