Effective Neutron Targets
Because of the lack of a free neutron target, deuterium targets have been used extensively in studying the neutron structure. The unique spin structure of the 3He ground state wave function and the recent developments in laser technologies made polarized 3He targets widely used in many experiments from neutron electromagnetic form factor studies to nucleon spin structure function measurements a...
متن کاملEstimation of neutron effective dose from DD and DT neutron generators and the design of appropriate shield for standing user
Neutron Generators (NG) are used as a neutron source for different applications. During recent years, major efforts are underway to develop a high yield compact NG. In this way, radiation protection aspects need to be considered during the operation of these high yield NGs. In this paper the neutron effective dose of a NG operator has been calculated using MCNPX Monte Carlo code. The results sh...
متن کاملHigh-Resolution Neutron Imaging of Laser-Imploded DT Targets
74 LLE Review, Volume 86 Imaging the neutrons produced by implosions at the National Ignition Facility1 or the Laser Mega Joule2 will require spatial resolution as good as 5 μm (Ref. 3) to identify failure mechanisms such as poor implosion symmetry or improper laser pulse shaping. An important step to achieving this goal is reported in this article. Neutron images were obtained from OMEGA implo...
متن کاملConstraining the neutron-proton effective mass splitting in neutron-rich matter
One of the most fundamental properties characterizing the propagation of a nucleon in nuclear medium is its effective mass[1, 2, 3]. The latter describes to leading order the effects related to the non-locality of the underlying nuclear effective interactions and the Pauli exchange effects in many-fermion systems. In neutron-rich matter, an interesting new question arises as to whether the effe...
متن کاملEffective mass of free neutrons in neutron star crust
The inner layers of a neutron star crust, composed of a Coulomb lattice of neutron rich nuclear clusters immersed in a sea of “free” superfluid neutrons, are closely analogous to periodic condensed matter systems such as electronic, photonic or phononic crystals. Applying methods from solid state physics to the neutron star context, we study the transport properties of those “free” neutrons for...
