“…Using an ethanol‐based suspension, the BS specimens were polished mechanically to yield a mirror‐like surface. The room‐temperature irradiation experiment with 6.0 MeV of Si 2+ generated by the 3‐MV tandetron accelerator was conducted at Sichuan University 64 . The beam flux was approximately 4.2 × 10 13 ions/(cm 2 s), and the samples were irradiated upon accumulating ion fluences of 8.0 × 10 14 and 1.1 × 10 15 ions/cm 2 , which roughly yielded average displacement per atom (dpa) values of 0.09 and 0.13, respectively.…”

The irradiation-induced temperature change on the glass surface was monitored by an FLIR thermal imaging camera, suggesting that the glass surface temperature variation remained within 200 • C. The stopping power (-dE/dx) and energy deposition of incident Si 2+ ions were estimated for each glass by using the SRIM2010 code, 65 and the damage profile was simulated using its option of "quick Kinchin and Pease calculation."…”

We examine the impact of the glass network-modifier cation field strength (CFS) on ion irradiation-induced mechanical property changes in borosilicate (BS) glasses for the ternary M 2 O-B 2 O 3 -SiO 2 systems with M = {Na, K, Rb} and the quaternary [0.5M (2) O-0.5Na 2 O]-B 2 O 3 -SiO 2 systems with M = {Li, Na, K, Rb Mg, Ca, Sr, Ba}. 11 B nuclear magnetic resonance (NMR) experiments on the as-prepared BS glasses yielded the fractional population of four-coordinated B species (B [4] ) out of all {B [3] , B [4] } groups in the glass network, along with the fraction of B [4] -O-Si linkages out of all B [4] -O-Si/B bonds. Both parameters correlated linearly with the (average) CFS of the M + and/or {M (2)+ , Na + } cations. Both the nanoindentation-derived hardness and Young's modulus values of the glasses reduced upon their irradiation by Si 2+ ions, with the property deterioration decreasing linearly with increasing M z+ CFS, that is, for higher M z+ ⋯O interaction strength. The irradiation damage of the glass network also increased linearly with the fraction of B [4] -O-Si linkages, which are the second weakest in the structure after the M z+ ⋯O bonds. Our results underscore the advantages of employing BS glasses with high-CFS cations for enhancing the radiation resistance for nuclear waste storage.

“…Figure 2 shows the control system architecture in the block diagram [14]. Interestingly, our accelerator system was the first one with ARGUS software deployment, and since then, ARGUS is now an integral part of Tandetron installations all over Europe and the world [15][16][17] which predicts potential interest of the ion beam facilities in MATLAB RBS channeling application. The Ion accelerator is operated by real-time TwinCAT SoftPLC interlinked with HVEE control software, ARGUS.…”

RBS Channeling MATLAB Application for Automated Measurement Control and Evaluation for 6MV Tandetron Accelerator

Rutherford backscattering spectrometry (RBS) in channeling regimes (RBS/C), as an ion beam analysis method performed on a Tandetron 6MV accelerator, generally gives precise information about the structure of crystalline samples by combining RBS signals in the random and aligned configurations. This paper presents details about the design and implementation of tailored RBS/C measurements (coarse and fine) and data evaluation application developed in MATLAB for in situ accelerator control system ARGUS, delivered by High Voltage Engineering Europa BV (HVEE). Additionally, we examined two different ways of stepping during the measurement to reduce the possible inaccuracies related with goniometer’s backslash affecting the evaluation of spectra. Verification experiment was carried out using a 2-MeV 4He+-beam directed on a Si (100) substrate. The channeling effect is seen as channeling dips of a lower signal in an otherwise rather homogeneous plane. Implemented application significantly facilitates the RBS/C measurement and analysis of the experiments, and also extends the ion beam analysis portfolio of Advanced Technologies Research Institute. Finally, software is ready-to-use for any Tandetron based ion beam facility with the ARGUS software for accelerator control.

“…Detection efficiency of the array was calibrated at the nuclear physics experiment (NPE) terminal of the 3-MV tandetron accelerator [15] at Sichuan university. Quasi Mono-energetic neutrons were produced using the 51 V(p, n) 51 Cr reaction (Q = -1534.8 keV) at incident energies between 1.7 and 2.6 MeV with a step of 0.15 MeV.…”

A low-background neutron detector array was developed to measure the cross section of the 13 C(α,n) 16 O reaction, which is the neutron source for the s-process in AGB stars, in the Gamow window (E c.m. = 190 ± 40 keV) at the China Jinping Underground Laboratory (CJPL). The detector array consists of 24 3 He proportional counters embedded in a polyethylene cube. Due to the deep underground location and a borated polyethylene shield around the detector array, a low background of 4.5(2)/hour was achieved. The 51 V(p, n) 51 Cr reaction was used to determine the neutron detection efficiency of the array for neutrons with energy E n < 1 MeV. Geant4 simulations, which were shown to well reproduce experimental results, were used to extrapolate the detection efficiency to higher energies for neutrons emitted in the 13 C(α,n) 16 O reaction. The theoretical angular distributions of the 13 C(α,n) 16 O reaction were shown to be important in estimating the uncertainties of the detection efficiency.
