nanoTDCR

Real-Time TDCR Counting System and Digital Pulse Processing MCA in One Package. The nanoTDCR is a triple-to-double coincidence ratio (TDCR) liquid scintillation counting system and multichannel analyzer (MCA).

There are two models to choose form: the TD9009 and TD9010. The TD9009 uses only PMT, while the TD9010 uses both PMT and SiPM. This table [pdf] provides a full comparison between the two models.

See a list of key features below and a combined data sheet for a full description of nanoTDCR’s features and specifications for both models.
