Low-temperature performance of a large area avalanche photodiode
A Large Area Avalanche Photodiode was studied, aiming to access its performance as light detector at low temperatures, down to 80 C. The excess noise factor, F ; was measured and found to be approximately independent of the temperature. A linear dependence of F on the APD gain with a slope of 0.0023970.00008 was observed for gains >100. The detection of low intensity light pulses, producing onl...
متن کاملPerformance of a Large Area Avalanche Photodiode in a Liquid Xenon Ionization and Scintillation Chamber
Scintillation light produced in liquid xenon (LXe) by alpha particles, electrons and gamma-rays was detected with a large area avalanche photodiode (LAAPD) immersed in the liquid. The alpha scintillation yield was measured as a function of applied electric field. We estimate the quantum efficiency of the LAAPD to be 45%. The best energy resolution from the light measurement at zero electric fie...
متن کاملModelling of High Quantum Efficiency Avalanche Photodiode
A model of a low noise high quantum efficiency n+np Germanium Photodiode utilizing ion implantation technique and subsequent drive-in diffusion in the n layer is presented. Numerical analysis is used to study the influence of junction depth and bulk concentration on the electric field profile and quantum efficiency. The performance of the device is theoretically treated especially at the wave-l...
متن کاملLarge area avalanche photodiode detector array upgrade for a ruby-laser Thomson scattering system
A low-cost upgrade has been implemented on the Madison Symmetric Torus ~MST! ruby-laser Thomson scattering ~TS! system to increase spectral coverage and substantially improve the signal-to-noise ratio ~SNR!. The spectral resolution has been increased from five channels on the long-wavelength side to an 11-channel system, which covers both sides of the laser line. Coverage on both sides of the s...
متن کاملStudies of Avalanche Photodiode Performance in a High Magnetic Field
We report the results of exposing a Hamamatsu avalanche photodiode (APD) to a 7.9 Tesla magnetic field. The effect of the magnetic field on the gain of the APD is shown and discussed. We find APD gain to be unaffected in the presence of such a magnetic field.
