Experimental subcritical facility driven by D-D/D-T neutron generator at BARC, India

The 67 Zn(n,p) 67 Cu, 64 Zn(n,2n) 63 Zn, 89 Y(n,γ) 90m Y and 89 Y(n,2n) 88 Y reaction cross sections relative to the 197 Au(n,2n) 196 Au monitor reaction have been determined at the neutron energy of 14.54 ± 0.002 MeV by using the method of activation and off-line γ-ray spectrometry. The neutron energy used was obtained from the 3 H(d,n) 4 He reaction. The covariance analysis was performed by taking the uncertainties arising in various attributes and the correlations between those attributes. The analyzed results from the present measurement were compared with the literature data and evaluated data of various libraries like ENDF/B-VIII, JEFF-3.3, JENDL-4.0 and ROSFOND-2010 libraries as well as with the calculated values based on TALYS-1.9 code.

“…The D + ions are generated in an RF ion source, which is extracted, focused, accelerated and incident on a tritium target. The deuteron ions incident on titanium-tritium (TiT) target was maintain at ground potential to produce 14.1 MeV neutrons through the 3 H(d,n) 4 He reaction [35]. In the present measurement the D + ion is accelerated to 99.71 kV which was impinge on titanium-tritium (TiT) target.…”

The cross sections for the 93 Nb(n,2n) 92m Nb, 93 Nb(n,α) 90m Y and the 92 Mo(n,p) 92m Nb reactions have been measured with respect to the 197 Au(n,2n) 196 Au monitor reaction at the incident neutron energy of 14.78 ± 0.19 MeV by employing methods of activation and off-line γ-ray spectrometry. The covariance analysis was carried out by taking into consideration of partial uncertainties in different attributes and correlation among the attributes. The present data have been compared with the literature data available in EXFOR, evaluated data of different libraries and theoretical values based on TALYS-1.8 code.

“…The deuteron ions impinge on titanium-tritium (TiT) targets (with copper backing), provides neutron energies of 14.1 MeV or 2.45 MeV via the T(d,n) 4 He or D(d,n) 3 He reactions, respectively. Due to shielding considerations, the maximum output of the assembly at present is limited to 10 10 n/s [8]. The target holder at the end of the accelerator tube contains TiT target of about 6-8 curie.…”

The 92 Mo(n,α) 89 Zr, 97 Mo(n,p) 97 Nb, 148 Nd(n,2n) 147 Nd and 146 Nd(n,p) 146 Pr reaction cross sections with the neutron of energy of 14.54 ± 0.24 MeV have been measured by using the method of activation and off-line γ-ray spectrometry. The neutron was generated from the D-T reaction at the PURNIMA neutron generator of BARC. The 197 Au(n,2n) 196 Au monitor reaction was used for the estimation of neutron flux. The covariance analysis for the uncertainties of the cross sections has been carried out by considering the partial uncertainties of different attributes. The present data have been compared with the literature data, evaluated data and theoretically calculated values from TALYS-1.9 code.
