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)
During the DAFNE [1] commissioning and run operations the Control System [2] has been continuously evolving in order to fulfill the user requirements and the needs of a complete accelerator management. The original structure of distributed CPUs relaying to a central shared memory proved to be scalable and suitable for adding functionality ’on the fly’.(More)
The SuperB project is an international effort aiming at building in Italy a very high luminosity ee (10 cm sec) 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 “crab waist”(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)
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 × 1030 cm–2 s–1 in single bunch mode and 5 × 1032 cm–2 s–1 in multibunch mode. Between the possible electromagnetic reactions at the interaction point, single bremsstrahlung (SB) has been selected for the(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 DA NE, 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(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)
Since the beginning of the past century, accelerators have started to play a fundamental role as powerful tools to discover the world around us, how the universe has evolved since the big bang and to develop fundamental instruments for everyday life. Although more than 15 000 accelerators are operating around the world only a very few of them are dedicated(More)
The e+ecollider DAΦNE, a 1.02 GeV c.m. Φ-factory, has reached a peak luminosity of about 1.4x10 cm s and a peak integrated luminosity in one day of about 8.6 pb. 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 have led to(More)
