accumulated charge density of c/cm , corresponding to about years of lhcb running at the highest background rate. we observe a rise in the dark current and noise measured with source off. the current drawn with source on steadily decreased, possibly indicating an increase of resistivity of the chamber plates...
mg/kg in metals causes embrittlement and can be determined with two neutron-based techniques: prompt gamma neutron activation analysis and neutron incoherent scattering. the latter technique has been demonstrated with cold neutrons at nist for hydrogen mass ratios up to mg/kg in mm thick titanium plates...
