Introduction:

1.PMT Tube Base Digital Multichannel Analyzer (Hereinafter referred to as TMCA) :

UltraBase Series TMCA is a high performance, tubular digital multichannel pulse amplitude analyzer, based on multiple communication interfaces (USB、RS485 or Ethernet interface), and match

various scintillator detectors, such as Nal(Tl) scintillator, or LaBr3(Ce) scintillator, and is connected to photomultiplier tubes (PMTs) with 8-stages or 10-stages dynode structure. UltraBase TMCA has

its own high-voltage unit to supply PMT high-voltage. Nuclear pulse signal is acquired and processed by digital signal processing, then transmit to special software installed on PC by USB/Ethernet,

carry out pulse waveform analysis and gamma spectrum analysis and activity calculation,etc.

TMCA installation is simple to connect to PC via USB or Ethernet interface, just load the software, use GMAS V1.0 to establish the communication and the measurement is started.

Applications:

Nuclear power, nuclear industry, environmental protection, medical treatment, sanitation and epidemic prevention, chemical industry and other fields. OEM products are available.

Features:

1) Integrated socket-type digital multi-channel based on USB/Ethernet interface, built-in high voltage, preamplifier and multi-channel pulse amplitude analyzer;

2) Wide adaptability: the 14-pin E687-14W tube socket is matched, and various scintillator probes such as NaI (Tl) and LaBr3 (Ce) can be connected externally. The parameters can be adjusted to match the characteristics of different detectors, and the high voltage of the probe can be adjusted;

3) Use FPGA to complete digital signal processing such as trapezoidal filter forming, stacking and discarding, fast forming, and automatic baseline restoration;

4) Compact structure, easy to carry, plug and play, directly connected with the photomultiplier tube holder;

5) The operation is convenient and flexible, and the nuclear pulse waveform analysis, gamma spectrum analysis and activity calculation can be performed through the special software on the PC side; adjust and set the parameters required by the user;

6) Built-in digital oscilloscope, which can observe the effect of digital signal processing and assist fault diagnosis;

7) An external temperature sensor can be connected to expand the spectrum stabilization system;

8) The supporting γ-spectrum measurement and analysis software is friendly in interface, powerful in function and easy to operate.
