Avalanche Photodiodes High Energy Radiation Detection Applications and Molecular Imaging
Large Area Si-APDs – UV-Enhanced APDs
The Large Area Silicon Avalanche Photodiode (Si-APD), C30739ECERH, is intended for use in a wide variety of broadband low light level applications covering the spectral range from below 400 nm to over 700 nm. It has low noise, low capacitance and high gain and is designed to have enhanced short wavelength sensitivity, with quantum efficiency of 60% at 430nm. This Si-APD is well suited for applications including molecular imaging, fluorescence detection and nuclear research.

The standard ceramic carrier package allows for easy handling and coupling to scintillating crystals such as LSO and BGO. Combined with the superior short wavelength responsivity, it makes this APD ideal in demanding applications such as Positron Emission Tomography (PET).

The C30626FH and C30703FH series are large area Si APDs in flat pack packages for either direct detection or easy coupling to scintillator crystals. The C30626 uses a standard reach through structure and has peak detection at about 900 nm. The C30703 is enhanced for blue wavelength response and has peak quantum efficiency at ~ 530 nm.

These APDs are packaged in square flat pack with or without windows or on ceramics. The no-window devices can detect direct radiation of X-rays and electrons at the energies listed, and the windowed packages are best for easy scintillator coupling.
