Physics: A New Reactor Physics Analysis Toolkit

Description: In the last year INL has internally pursued the development of a new reactor analysis tool: PHISICS. The software is built in a modular approach to simplify the independent development of modules by different teams and future maintenance. Most of the modules at the time of this summary are still under development (time dependent transport driver, depletion, cross section I/O and interpolation, generalized perturbation theory), while the transport solver INSTANT (Intelligent Nodal and Semi-struc… more

Physics design requirements for the Tokamak Physics Experiment (TPX)

Description: The design of TPX is driven by physics requirements that follow from its mission. The tokamak and heating systems provide the performance and profile controls needed to study advanced steady state tokamak operating modes. The magnetic control systems provide substantial flexibility for the study of regimes with high beta and bootstrap current. The divertor is designed for high steady state power and particle exhaust.

[Experimental nuclear physics]. [Physics Dept. , Yale Univ]

Description: An earlier study of unusual electromagnetic decays in [sup 86]Zr was extended in order to make comparisons with its isotone [sup 84]Sr and with [sup 84]Zr. The K=14 (t [sub [1/2]] = 70 ns) high-spin isomer in [sup 176]W was found to have a 13% branch directly to the K=O ground-state band, one of the strongest violations of K-selection rules known. A new program to search for a predicted region of oblate deformation involving neutron deficient isotopes in the Rn/Fr/Ra region was begun. In the ar… more

Recent results on top quark physics and B physics at CDF

Description: We present the recent results on top quark physics and B physics with the Collider Detector at Fermilab (CDF). These results come from analyses using a full data sample at an integrated luminosity of 109 pb{sup -1} cross section in 1.8-TeV p{anti p} collisions. We measure the top quark mass to be 175.8{+-}6.5 GeV/c{sup 2} and the t{anti t} production cross section to be 7.6{sup +1.8}{sub -1.5} pb. We also present measurements of the lifetimes of B-hadrons and the time- dependent B{sup 0}-{anti … more
