Mathematical model of the electronuclear set-up on the beam of JINR synchrotron
Abstract
On the basis of the Monte Carlo code CASCADE, developed at JINR, a mathematical model of the deep-subcritical set-up with the uranium blanket used in experiments underway at JINR using a 0.6-4 GeV proton beam, is created. The neutron spectra, yields and energies of generated particles are calculated and compared for several modifications of the set-up. The influence of paraffin and graphite moderators on the characteristics of the particles escaping the lead target is studied. The modelled set-up can be considered as a first step of the experiments to be designed at JINR U-Pu accelerator driven subcritical systems-subcritical assembly at Dubna (ADS-SAD) with a heat power of several tens of kW.
