"The EA operates indefinitely in a closed cycle, namely the discharge of a fuel load, with the exception of fission fragments, is re-injected in the sub-critical unit with the addition of natural Thorium to compensate for the burnt fuel. After many cycles ...
We are interested in the mortar spectral element discretization of the Stokes problem in a two-dimensional polygonal domain. We propose a family of residual type error indicators and we prove estimates which allow us to compare them with the error. We expl ...
"Several cyclotron-based high intensity accelerators have been studied in the framework of the Energy Amplifier (EA) project proposed by Prof. C. Rubbia [1]. Among them, two basic designs are presented: a 380 MeV separated sector cyclotron delivering a hig ...
This paper presents the development of spectral element methods to simulate unsteady flows of viscoelastic fluids using a differential constitutive equation. Preliminary results for simple test problems are discussed as well as possible techniques to impro ...
A preliminary study of the radio-frequency cavities for the EULIMA separated sector cyclotron is presented. A symmetrical cavity scheme with a multi-stem delta-shaped electrode has been studied. Numerical computations and model measurements have shown that ...
"The goal of this accelerator complex is to provide a 10 MW proton beam for driving the Energy Amplifier recently proposed by C. Rubbia [1]. It is lower (by one order of magnitude) than the requirements of most of the accelerator-ddrive projects based on c ...
"A high efficiency three-stage cyclotron has been proposed [1] to provide a 10 MW proton beam in the 1 GeV kinetic energy range for driving the Energy Amplifier. This accelerator complex consists of the following chain: two 15 MeV compact isochronous caylo ...
The goal of the proposed three-stage cylotron complex is to deliver a continuous external high energy (in the 1 GeV range) proton beam of the order 10 mA for driving the Energy Amplifier, a hybrid sub-critical nuclear system, which is being deveoped at CER ...
A status report on the feasibility studies for the EULIMA medical accelerator project is given. Recent advances in the assessment of the various basic accelerator types ofr the facility are presented in terms of their advantages for heavy ion beam accelera ...
The control system for the LEP machine is based on the concept of distributed intelligence. Hence the controls for the Vacuum System have to follow the same approach. There are a number of benefits available from having disctributed computing power, among ...
