CERN has been building a transportable RFQ for use in the examination of art masterpieces based mainly on the PIXE (Proton Induced X-ray Emission) technique with an extracted beam. This new PIXE-RFQ accelerator is very compact, only one meter in leng

The effect of Nd substitution at the Ba sites has been studied in Nd1+xBa2-xCu3Oy system for 0.1 ≤ x ≤ 0.35. Orthorhombic to tetragonal structural phase transition occurs at about x = 0.17. With the increase of Nd, the Tc value decreases and ΔT

Careful characterization of (Y0.95Sr0.05)(Ba1.5Sr0.5)Cu3O7−δ and Y(Ba1.5Sr0.5)Cu3O7−δ ceramic samples has confirmed the simultaneous substitution of Sr for both Y and Ba in the YBa2Cu3O7 structure. The substitution at the Y site has a distinct

Based on the granular model of ceramic superconductors, it is shown that the magnetoresistance associated with dissipation in Josephson junctions is an excellent magnetometer with which to determine the field at the surface of superconducting grains.

The behaviour of a high-Tc superconductor YBa2Cu3O7-x subjected to a microwave e.m. field is presented. The experimental results, regarding the Q-factor of a microwave cavity (of which the sample is a part) as a function of temperature and external m
