The principal characteristics of neutron activation analysis facility REGATA 

Distance between irradiation  and measurement positions 


(Ch1-cadmium case) 


60 m

70 m

Air pressure  3-7 bar
Transportation capsule types


polyethylene,  teflon, 

aluminum, titanic

Internal volume of transportation capsule (Ø 16  mm, H - 22- 35 mm)  3.5 – 5.5 сm3 

Maximum irradiation time with 2.0 Mw power for capsules:



0.5 h

3 h

Transportation time for capsule:

teflon , aluminum 

10-20 s

3-8 s

Thermal neutron flux     Ch2 1.5× 1012 n/s сm2
Resonance neutron flux    Ch1 3.6× 1011 n/s сm2
Mass of sample for analysis depends from type of sample 1 mg – several grams


Detection limit depends on elemental composition of the sample and type of sample and can reach, for example, 10-10  for vegetable samples. Around 45 elements can be determined for such type of samples.


The principal characteristics of  spectrometers and spectra analysis

- Four HPGe detectors with efficiency 40-55% and resolution 1.8-1.9 keV (Canberra)
- Spectrometric electronics - analog type and digital processors (Canberra)
- Automated system for spectra measurement for three detectors
- Software for spectra analysis - Genie-2000 (Canberra)
- Software package for storage of information and automation of all stages of NAA (FLNP JINR)
- Low background detector with low background shield (Canberra) for measurement of environmental samples
