Towards microwave modulation in a wavelength-tuned magneto-optical trap
... The purpose of microwave modulation is to generate the additional re-pump frequencies needed. The setup must modify the laser diode injection current [11] and produce sidebands (also known as frequency chirps [1]) onto the main laser light. The two important points that need to be discussed are the ...

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.
