Physics with High Intensity Neutron Sources

Development of a Position Sensitive Neutron Detector with High Efficiency and Energy Resolution for Use at High-Flux Beam Sources

We are developing a high-efficiency neutron detector with 1 cm position resolution and coarse energy resolution for use at high-flux neutron source facilities currently proposed or under construction. The detector concept integrates a segmented (3)He ionization chamber with the position sensitive, charged particle collection methods of a MicroMegas detector. Neutron absorption on the helium pro...

Search for Time-Reversal Invariance Violation with High Intensity Neutron Beam

The important advantage to the search for Time-Reversal invariance violation (TRIV) in neutron nuclei interactions is the possibility of an enhancement of T-violating observables by many orders of magnitude due to the complex nuclear structure (see, i.e. paper [1] and references therein). Moreover, the variety of nuclear systems to measure T-violating parameters provides assurance that a possib...

High Energy Beam-beam Effects in Clic

In order to achieve high luminosity, the Compact Linear Collider (CLIC) has to be operated in the highbeamstrahlung regime at centre-of-mass energies in the few TeV range. Beam-beam effects for this case are simulated. The dependence of luminosity, luminosity spectrum and background conditions on the different beam parameters is investigated. In particular the effect of beam size, waist shift a...

The effect of high-energy electron beam on drawn and undrawn high density polyethylene fibers

HDPE monofilaments were obtained using different extruders and drawn by post-extruder equipments. After solidification, drawn and undrawn monofilaments (draw ratio 7:1) were irradiated with 10 MeV electron beams in air at room temperature at 25, 50, 75, 100 and 125 kGy dose ranges to induce a network structure. HDPE crosslinking was studied on the basis of gel content measurements. The fibers w...
