Single Channel Analyser Type : SC530 manufactured by NUCLEONIX is designed primarily to be a constituent unit of Modular Gamma Ray Spectrometer Type : GR611M.
Single Channel Analyser SC530 is essentially used for pulse height analysis. It has THREE modes of operations namely INTEGRAL, NORMAL & WINDOW. In Gamma Ray Spectrometer the scintillation detector pulse output is proportional to the Gamma Energy and hence accurate measurement of pulse height by Single Channel Analyser will give the energy information. |
Features
- Accepts both positive unipolar or bipolar pulses as input
- Modes : INTEGRAL, NORMAL & WINDOW modes of operation
- Discriminator : LLD & ULD
- Output : Positive TTL
- Window width constancy, better than 30mV
