New MPPCs and MPPC-modules

(PresseBox) ( Herrsching am Ammersee, )
Hamamatsu Photonics expand the product range of MPPC-arrays and -modules with new monolithic arrays. Due to the compact construction a maximum position resolution with minimum dead space is possible. All arrays feature 16 channels (4x4 MPPCs) and are available in SMD (S11828-334M) and PWD (S11827-3344MG) package. The active area of each MPPC is 3x3 mm2. The amount of APDs per channel is 3600 e.g. with an active area of 50μm each and typical dark current of 3μA. The arrays could be read out by a FPC output (S11829-3344MF und S11830-3344MF).

Additionally a 64 (8x8 MPPCs, S11834-3388DF) channel MPPC-array with the same cable type output is available. The special design allows the arrangement of multiple devices in a modular format.

Together with a high voltage supply, read out circuit and DA-converter as well as a temperature control the arrays are available in compact modules. Read out electronics allow either parallel voltage outputs for each channel or a summed voltage from all channels. The modules improve evaluation of 16 channel MPPC-array e.g. and guarantee stable results. Moreover the compact design of the modules allows assembling of bigger arrays.

These new MPPC-arrays and modules are designed especially for low light level applications to the point of single photon counting. They are applied in those applications where additional requirements like compact design, low current consumption and good shielding against magnetic fields have to take into account as required in high energy physics and PET-applications in medical technologies.
