The principal characteristics of neutron activation analysis facility REGATA
|
Distance between irradiation and measurement positions (Ch2) (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: polyethylene teflon |
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. |
