Multi-Channel Analyzer (MCA) is an important part of nuclear spectroscopy system. The major requirement of MCA is for nuclear Pulse Height Analysis(PHA) in energy spectroscopy. The USB-MCA presented here, incorporates state of art technologies like FPGA, USB bus interface and precision analog electronics to meet the stringent system requirements in nuclear pulse spectroscopy. The resolution supported by the USB-MCA ranges from 256 channels to 1K/8K channels selectable via software, making it suitable for all spectroscopy applications of low resolution (e.g. NaI-PMT).

The USB bus interface of the MCA provides an excellent connectivity with most of the new PCs and lap-top computers meeting minimum requirements of PC. The ANUSPECT application software provided with the USB-MCA, seamlessly integrates with the hardware, featuring a range of standard functions required for analysis and acquisition.


Note: 1K/8K MCA & Anuspect processing software are manufuctured & supplied by NUCLEONIX based on Baba Atomic Research Centre,Technology.

ACCESSORIES FOR INTEGRAL MCA MODULE MC 1000

(a) SCINTILLATION DETECTORS

Nucleonix Systems offers wide range of NaI Scintillation Detectors of different sizes both with flat & well type crystals, to meet the requirements of wide range of users for Gamma ray spectrometry measurements.
Scintillation detectors offered for teaching labs include 1"x1" & 2"x2" NaI integral assemblies with built-in pre-amplifiers. These detector assemblies give excellent stability, superior performance & good resolution in the range of 7.0 to 8.5% for Cs-137. Scintillation detectors of other sizes can be offered against user specific requirements also. For teaching labs we recommend 1"x1" or 2"x2" NaI detector with this integral model.
