Description
Low energy charged particle reactions determine the nuclear burning in different phases of stellar evolution. The ashes provide the seed and fuel for subsequent evolution phases and also determine the seed material for nuclear processes in subsequent cataclysmic events. The charged particle reactions have extremely small cross sections. The direct measurement is extremely challenging because of the low reaction rate and the large cosmogenic, radiogenic, and beam induced background in the detectors.A deep underground location for the accelerator laboratory removes the cosmic ray background, a substantial component in the experimental spectra. The talk presents present initiatives and developments of underground accelerator labs and gives a summary of the present progress in the measurement of critical low energy reactions.
