Abstract

For an external radiotherapy procedure, the tissue phantom ratio (TPR20,10) is used as a quality index. This work presents an estimate of TPR20,10 using two cylindrical ionization chambers (NE2571 Farmer and PTW30013) in three high-energy photon modes (6, 10 and 15 MV) using both the Monte Carlo (MCNP) process and the experimental setup. The MCNP (version MCNP5) was used for the simulation of photon beams delivered by Varian-2300CD for the determination of TPR20,10 according to technical report series (TRS) 398. Again applying the same protocol TPR20,10 values were measured experimentally with NE2571 Farmer and PTW30013 chambers for the same medical linear accelerator (LINAC). The differences of TPR20, 10 between MCNP and experimental values were found for NE2571 Farmer chamber within 4.17 percent, 2.9 percent and 2.5 percent and similarly, these were within 3.89 percent, 2.71 percent and 1.98 percent at 6, 10 and 15 MV respectively for PTW30013. The TPR20,10 values simulated by our calculated MCNP demonstrated strong agreement with our experimental results.

Abstract

According to IAEA TRS-398 protocol the Tissue Phantom Ratio, TPR20, 10, is used as a quality index for the megavoltage photon beam in external beam radiotherapy. This work presents a calculation of TPR20, 10, in two high energy photon modes using FC65-G thimble type cylindrical ionization chambers with the help of Monte Carlo method. The MCNP (version MCNP5) code was used for the simulation of photon beams delivered by Varian-2300CD Clinac accelerator head. The TPR20, 10 values were also measured experimentally using the same chamber. The calculation of TPR20, 10 using MC simulation showed good agreement with our experimentally determined values. The TPR20, 10 discrepancies of Monte Carlo and experimental values were found within 3.12% and 2.7% for 6 MV and 10 MV photon beams respectively. As MCNP simulated values showed good agreement with experimentally determined values, so this simulation technique should be applicable for the further research in reference dosimetry.

Abstract

The neutron total cross-sections of molybdenum were measured in the neutron energy region from 0.01 eV to 200 eV by using the time-of-flight method at the Pohang Neutron Facility, which consists of an electron linear accelerator, a water-cooled tantalum target with a water moderator, and a 12-m long time-of-flight path. A 6 Li–ZnS(Ag) scintillator with a diameter of 12.5 cm and a thickness of 1.6 cm was used as a neutron detector, and a high purity natural molybdenum metallic disc with a diameter of 6.2 cm and a thickness of 3 mm thickness was used for the neutron transmission measurement. Notch filters composed of Co, In, Cd were used to estimate the background level and to calculate the length of neutron flight path. In order to reduce the gamma-ray background from Bremsstrahlung and from neutron capture, we employed a neutron–gamma separation system based on their different pulse shapes. The present measurement was compared with the existing experimental and the evaluated data. The resonance parameters of Mo isotopes were extracted from the transmission by using the SAMMY code and were compared with other previous reported results.

Abstract

The neutron-induced fission cross-section of 233U has been measured at the CERN n_TOF facility relative to the standard fission cross-section of 235U between 0.5 and 20MeV. The experiment was performed with a fast ionization chamber for the detection of the fission fragments and to discriminate against α -particles from the natural radioactivity of the samples. The high instantaneous flux and the low background of the n_TOF facility result in data with uncertainties of ≈ 3% , which were found in good agreement with previous experiments. The high quality of the present results allows to improve the evaluation of the 233U (n,f) cross-section and, consequently, the design of energy systems based on the Th/U cycle.

Abstract

The successful development of advanced nuclear systems for sustainable energy production and nuclear waste management depends on high quality nuclear data libraries. Recent sensitivity stud- ies and reports [1-3] have identi ed the need for substantially improving the accuracy of neutron cross-section data for minor actinides. The n TOF collaboration has initiated an ambitious exper- imental program for the measurement of neutron capture cross sections of minor actinides. Two experimental setups have been constructed for this purpose: a Total Absorption Calorimeter (TAC) [4] for measuring neutron capture cross-sections of low-mass and/or radioactive samples and a set of two low neutron sensitivity C6D6 detectors for the less radioactive materials.

Abstract

The Pohang Neutron Facility, which consists of an electron linear accelerator, a water‐cooled Ta target with a water moderator, and a time‐of‐flight path with an 11 m length has been operated since 2000. We report the status activities on the neutron total cross‐section measurements in the neutron energy region from 0.01 eV to 100 eV by the neutron time‐of‐flight method at Pohang Neutron Facility. A 6Li‐ZnS(Ag) scintillator with a diameter of 12.5 cm and a thickness of 1.5 cm has been used as a neutron detector. The background level has been determined by using notch‐filters of Co, In, and Cd sheets. In order to reduce the gamma rays from Bremsstrahlung and that from neutron capture, we have employed a neutron‐gamma separation system based on their different pulse shape. The present measurements for Ag, Hf, and Ta samples are compared with the previous ones and the evaluated data in ENDF/B‐VI. The resonance parameters for Ag and Hf samples have been extracted from the transmission data by using the SAMMY ...

Abstract

Neutron-induced ssion cross-sections of minor actinides have been measured using the n TOF white neutron source at CERN, Geneva, as part of a large experimental program aiming at collecting new data relevant for nuclear astrophysics and for the design of advanced reactor systems. The measurements at n TOF take advantage of the innovative features of the n TOF facility, namely the wide energy range, high instantaneous neutron ux and good energy resolution. Final results on the ssion cross-section of 233U, 245Cm and 243Am from thermal to 20 MeV are here reported, together with preliminary results for 241Am. The measurement have been performed with a dedicated Fast Ionization Chamber (FIC), a ssion fragment detector with a very high e ciency, relative to the very well known cross-section of 235U, measured simultaneously with the same detector.
