Autor: Giovanni Mattei, Paolo Mazzoldi, S. Zandolin, Giancarlo Battaglin, G. W. Arnold

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. :440-444

Profilometer step-height measurements, ion-beam analysis, and electron microscopy have been used to characterize the structural changes and hydration of argon, krypton, and xenon implanted fused silica and soda-lime glass. For both glasses, a structu

Erosion, redeposition and boronization lifetime in RFX

Autor: Elti Cattaruzza, D Boscarino, V. Antoni, L. Tramontin, V. Rigato, Mario Bagatin, S. Zandolin

Publikováno v: Journal of Nuclear Materials. :709-713

In this paper the boronization lifetime in the reversed field pinch experiment RFX is discussed. It is found that the redeposition of carbon-rich layers, which grow during plasma exposure, cover the boron containing layers preventing the getter effec

Surface treatment of HV electrodes for superconducting cyclotron beam extraction

Autor: Lorenzo Torrisi, S. Zandolin, V. Rigato, Giacomo Cuttone, C. Marchetta, Alberto Quaranta, G. Delta Mea

Publikováno v: IEEE Transactions on Dielectrics and Electrical Insulation. 4:218-223

At the Istituto Nazionale di Fisica Nucleare Laboratorio Nazionale del Sud of Catania, a K=800 superconducting cyclotron is in operation since 1994. The accelerator beam extraction is accomplished using electrostatic deflectors constituted by HV elec

Publikováno v: Scopus-Elsevier

Wide band gap a-SiC:H and a-SiN:H films have been deposited by ultra high vacuum plasma enhanced chemical vapor deposition. For a-SiC:H films SiH 4 + CH 4 , SiH 4 + CH 4 + H 2 and SiH 4 + C 2 H 2 gas mixtures have been used, whereas for a-SiN:H films

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. :262-265

The complementary nuclear techniques of PIXE, PIGE, SEM and EDAX were employed to the study of geological samples from Wuyo, North East of Nigeria. The geological samples studied include (i) sandstones (fresh, mylonised and silicified), (ii) granites
