17. Beam optics and magnet studies for neutralizer storage rings

Marco Cavenago (INFN-LNL)

3/14/16, 4:35 PM

The design of efficient storage rings with large acceptance so that a neutralizer gas cell can be inserted requires both linear matrix formalism and full field tracking calculation. Moreover large magnet aperture must be considered. First an unbiased search of suitable lattices is needed. Matrix formalism is simple enough to allow use of symbolic manipulation programs, with s the beam...

14. High current negative ion source with Planar Funnel extraction grid

Vincenzo Variale (INFN-BA)

3/14/16, 4:35 PM

High current large negative (H-, D-) ion sources will produce the neutral beams needed for fusion plasma heating in ITER. To reach very high negative ion beams a cesium coated surface of the plasma grid is usually used. The cesium coating however, poses some problem in the maintenance and operation of the ion source and for that alternative ways to enhance the ion current extraction should be...

16. High current storage rings for neutral beam injectors

Marco Cavenago (INFN-LNL)

3/14/16, 4:35 PM

The gas neutralizer converter used to produce a neutral hydrogen (or deuterium) beam from a H- (or D-) beam has intrinsic limitation on conversion efficiency and requires a residual ion dump for H-, and produced H+. By recirculating H- into gas neutralizer N times (with N up to 4) conversion efficiency can be increased and the ion dump size is greatly reduced. In other words, the gas...

22. New thermal neutron source at LNL

Enrico Fagotti (INFN-LNL)

3/14/16, 4:35 PM

In the framework of MUNES project, a new neutron source was developed at the CN electrostatic accelerator of Legnaro National Laboratories. Neutrons are produced thruogh Be(p,n) reaction using a thin foil beryllium target brazed on a copper base. A 5 MeV, 3 microA proton beam is focalized onto the target so as to reach a 500 W/cm^2 power density on beryllium, the same as MUNES high intensity...

2. Surface dependence for laser - induced target current by plastic materials

Ernesto Giuffreda (Università del Salento, Lecce)

3/14/16, 4:35 PM

Laser - matter interactions are a wide field of physics in which many parameters are involved. A small change in one of them can lead to a completely different time evolution for the physical system. In this work, the characterization of a plastic target subjected to a laser irradiation has been studied. A focus was particularly devoted to the interaction of the target with the whole...
