We describe the status of the effort to realize a first neutrino factory and the progress made in understanding the problems associated with the collection and cooling of muons towards that end. We summarize the physics that can be done with neutrino factories as well as with intense cold beams of muons. The physics potential of muon colliders is reviewed,(More)
With an aim to develop mapping population on fibre fineness trait, grouping of 16 selected jute accessions, eight each from Corchorus olitorius and Corchorus capsularis which showed promising agronomic characteristics, was carried out using fibre fineness data and DNA fingerprinting using SSR and RAPID primers. Based on fibre fineness trait two subgroups(More)
In a Maxwellian view, an accelerator of charged particles converts electromagnetic field energy into mechanical energy of the particles. A conventional accelerator based on a resonant cavity emphasizes interference between the drive fields and the the spontaneous radiation fields (those fields radiated when charged particles pass through an otherwise empty(More)

Our primary role in the genesis of PEP-II, the energy-asymmetric B-meson factory at the Stanford Linear Accelerator Center, has since evolved into a major collaborative construction project. The project, when completed, will greatly facilitate the study of CP violation. Our scientists and engineers remain involved with PEP-II, especially in beam dynamics(More)
The charge dynamics at the surface of the transparent conducting oxide and photoanode material ZnO are investigated in the presence and absence of light-harvesting colloidal quantum dots (QDs). The time-resolved change in surface potential upon photoexcitation has been measured in the m-plane ZnO (101[combining macron]0) using a laser pump-synchrotron X-ray(More)
