We present in this paper new and updated calculations of the ionization equilibrium for all the elements from H to Ni. We collected for these elements all the data available in the literature for the ionization and radiative plus dielectronic recombination rates. In particular, the dielectronic rates have been fitted with a single formula and the related(More)
Progress in thermonuclear fusion energy research based on deuterium plasmas magnetically confined in toroidal tokamak devices requires the development of efficient current drive methods. Previous experiments have shown that plasma current can be driven effectively by externally launched radio frequency power coupled to lower hybrid plasma waves. However, at(More)
The SuperB project is an international effort aiming at building in Italy a very high luminosity e + e − (10 36 cm-2 sec-1) asymmetric collider at the Y(4S) energy in the CM. The accelerator design has been extensively studied and changed during the past year. The present design, based on the new collision scheme, with large Piwinski angle and the use of "(More)
The main goal of FTU lithium liquid metal experiments was to demonstrate the capability of the Capillary Porous System (CPS), firstly tested on T-11 tokamak, to confine liquid lithium avoiding sudden release as consequence of j×Β electromagnetic force on the surface. These latter should be balanced by the surface tension forces associated to the liquid(More)
The e+e-collider DAΦNE, a 1.02 GeV c.m. Φ-factory, has reached a peak luminosity of about 1.4x10 32 cm-2 s-1 and a peak integrated luminosity in one day of about 8.6 pb-1. With the current rates the physics program of the three main experiments DEAR, FINUDA and KLOE will be completed by the end of 2007. In this paper we describe in detail the steps which(More)
In modern tokamaks visible and infrared video cameras are becoming more and more important to monitor plasma evolution during fusion experiments. Analyzing these images in real-time can provide relevant information for controlling the plasma and the safety of the machines. The realtime image processing capability of Cellular Nonlinear Network based chip has(More)
We investigate the phenomena related to the emission of coherent synchrotron radiation (CSR) in the Terahertz frequency range at the DAΦNE collider. In particular, we calculate the threshold for the synchrotron radiation (SR) induced single bunch instability, usually referred as microbunching instability (MBI) [1-4]. The MBI can potentially have some effect(More)
The operation of DANE, the 1.02 GeV c.m. e + e-collider of the Frascati National Laboratory with the KLOE experimental detector was successfully concluded in March 2006. Since April 2004 it delivered a luminosity > 2 fb-1 on the peak of the resonance, > 0.25 fb-1 off peak and a high statistics scan of the resonance. The best peak luminosity obtained during(More)
DAΦNE, the Frascati Φ-factory, is an e + /e – collider with 2 interaction points (IPs). The center of mass energy is 1020 MeV and the design luminosity 4.2 × 10 30 cm –2 s –1 in single bunch mode and 5 × 10 32 cm –2 s –1 in multibunch mode. Between the possible electromagnetic reactions at the interaction point, single bremsstrahlung (SB) has been selected(More)
