The use of synchrotrons for pulsed neutron spallation sources is an example of spin-off from the accelerator development prompted by particle physics. The first proposal for an accelerator-driven source with a thermalised neutron facility was in the 1960s (Intense Neutron Generator, ING) [1], but this project was never built. There was earlier work on 'electrical' breeders [2] and the direct bo...
The ablator couples energy between the driver and fusion fuel in inertial confinement fusion (ICF). Because of its low opacity, high solid density, and material properties, beryllium has long been considered an ideal ablator for ICF ignition experiments at the National Ignition Facility. We report here the first indirect drive Be implosions driven with shaped laser pulses and diagnosed with fus...
A compact, step range filter proton spectrometer has been developed for the measurement of the absolute DD proton spectrum, from which yield and areal density (ρR) are inferred for deuterium-filled thin-shell inertial confinement fusion implosions. This spectrometer, which is based on tantalum step-range filters, is sensitive to protons in the energy range 1-9 MeV and can be used to measure pro...
The proton matrix element of the isovector-scalar density, 〈p|uu−dd|p〉/2Mp, is calculated by evaluating the nucleon current correlation function in an external isovector-scalar field using the QCD sum-rule method. In addition to the usual chiral and gluon condensates of the QCD vacuum, the response of the chiral condensates to the external isovector field enters the calculation. The latter is d...
This paper summarizes recent results on non-SUSY searches at the Fermilab Teva-tron p p collider. All the analysis are based on the complete data samples recorded by both the CDF and DD collaborations during the 1992-1995 running period (Run I), and correspond to 100 pb ?1. Searches for new neutral heavy vector bosons, leptoquarks, dijet mass resonances, and associated production of new heavy s...
