The Ps 80 Mhz Cavities
As part of the preparation of the PS as injector for LHC, two new 80 MHz cavities have been designed and built at CERN. Bunches spaced by 25 ns and less than 4 ns long are required at injection into the SPS. The bunch spacing is obtained with a 40 MHz system installed in the PS in 1996, but the nominal small bunch length will only be obtained with the 80 MHz systems producing a total of 600 kV....

We investigate in this paper the performance of a simple file sharing principle. For this purpose, we consider a system composed of N peers becoming active at exponential random times; the system is initiated with only one server offering the desired file and the other peers after becoming active try to download it. Once the file has been downloaded by a peer, this one immediately becomes a ser...

In this paper, we introduce the notion of fuzzy dot PS-subalgebras in PSalgebras and establish its various properties.
متن کاملEnhanced Ps-Ps interactions due to quantum confinement.
Slow positrons implanted into a porous silica film may efficiently form positronium (Ps) atoms that diffuse through a network of interconnected pores. At high Ps densities, the long lifetime of ortho-positronium atoms is reduced due to Ps-Ps spin dependent interactions at a rate that implies an effective free-space scattering cross section, σ(e) = (3.4 ± 0.5) × 10(-14) cm(-2), at least 25 times...
متن کاملMending your Ps & Qs
0. Introduction Phonological representations include sequences of featural specifications, pq. Two properties can be observed about such sequences: (i) for a sequence pq to be of significance for the phonology of a language, p must be perceptibly different than q; (ii) to produce a sequence pq, the articulators must start in the configuration for p and then change into the configuration for q. ...
