The SINQ gas-jet facility as a source for radionuclides from neutron-induced fission of 235U

نویسندگان

چکیده

The Swiss Spallation Neutron Source SINQ of the Paul Scherrer Institute provides neutrons via proton-induced spallation reactions in a lead target. Produced are thermalized and impinge on 235U-targets, enclosed three-part chamber assembly, which is located inner wall shielding. thermal-neutron-induced fission products can be readily transported from this assembly to radiochemical laboratory using gas-jet technique either with pure carrier gas or an aerosol-particle-loaded gas. In past, mainly radioisotopes elements Se, Br, Rb, Kr were retrieved used for gas-phase chemistry experiments. Here, we present first experiments after commissioning facility as source recoverable, non-volatile volatile, carrier-free general studies other applications.

Measurement of neutron induced fission of 235U, 233U and 245Cm with the FIC detector at the CERN n TOF facility

A series of measurements of neutron induced fission cross section of various TRU isotopes have been performed at the CERN n TOF spallation neutron facility, in the energy range from thermal to nearly 250MeV. The experimental apparatus consists in a fast ionization chamber (FIC), used as a fission fragment detector with a high efficiency. Good discrimination between alphas and fission fragments ...

Effects of Neutron Emission on Fragment Mass and Kinetic Energy Distribution from Thermal Neutron-Induced Fission of 235U

The mass and kinetic energy distribution of nuclear fragments from thermal neutroninduced fission of U(nth, f ) have been studied using a Monte-Carlo simulation. Besides reproducing the pronounced broadening in the standard deviation of the kinetic energy at the final fragment mass number around m = 109, our simulation also produces a second broadening around m = 125. These results are in good ...

Nucleon pair breaking in the thermal neutron induced fission of 233U and 235U

2014 The absence of a systematic even-odd effect in the primary fragment mass distributions, which has been recently observed, is discussed in terms of nucleon pair breaking during the saddle to scission transition. It is concluded that the existing experimental data are compatible with the assumption of a process where at least one nucleon pair is broken. J. Physique 44 (1983) 785-790 JUILLET ...
