NEW DESIGN: High sensitive spectrometric SELDI detector on
the base on new light collection system and module concept.
Seldi is a series of scinti-electronic radiation detectors on the
basis of "scintillator - photodiode" assembly.
At present a concept of a module-type detection block has been
developed. Such block is mounted of individual modules with a specified energy
resolution. Each module is designed so that to provide a maximum light yield and
energy resolution. The number of modules is defined proceeding from the required
sensitivity of the block as a whole. The block is positioned in a common housing
with a common scheme of signal processing from all the modules.
The module-type block allows to determine the direction to the radiation source
while not displacing the block. The ratio "signal-noise" has been improved.
The base detection blocks with the crystal volume from 8 to 64 and energy
resolution by 137Cs from 5.5 to 14% have been developed.
The consumption power for one module - 60 mWt.
