Self-aligned VCSEL-microlens scanner with large scan range

This paper reports on the design, fabrication and optical characterization of a self-aligned microlaser scanning system consisting of a vertical cavity surface emitting laser (VCSEL) source and a MEMS-actuated microlens scanner. The alignment and the spaci ...

Cavitation in impacted drops and jets and the effect on erosion damage thresholds

Mohamed Farhat, Danail Obreschkow, Marc Tinguely

It is well known that metals and alloys erode at lower impact threshold velocities than expected. This was studied by Thomas and Brunton (1970) who reported “discrepancy factors” in the range 4–10. These authors suggested that liquid impact was a more sear ...

Deposition Processes with Hardcore Behaviour

Particles are deposited onto a surface with discrete sites. They are subject to an inhibition by which they cannot pass close by a particle already fixed on the surface. This implies that the surface builds up with vertical gaps between the particles. In t ...

Analysis of selected Phenix EOL tests with the FAST code system - Part I: Control-rod-shift experiments

Rakesh Chawla, Konstantin Mikityuk, Aurélia Chenu

The end-of-life (EOL) tests recently performed at the Phenix reactor present a unique opportunity to validate computational tools used for Sodium-cooled Fast Reactor (SFR) static and transient analysis. In the first part of the current study, PSI's FAST co ...

Plasma Isotopic Effect on the Damping Rate of Toroidal Alfven Eigenmodes with Intermediate Toroidal Mode Numbers

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard, Theodoros Panis

This paper reports on the results of recent experiments performed on the JET tokamak on toroidal Alfvén eigenmodes (TAEs) with toroidal mode number (n) in the range up to |n|=7. The stability properties of these medium-nTAEs are investigated experimentally ...

Effects of an Asymmetric Chamber on the Beam Coupling Impedance

Carlo Zannini, Giovanni Rumolo

The wake function of an accelerator device appears to have a constant term if the geometry of the device is asymmetric or when the beam passes off axis in a symmetric geometry. Its contribution can be significant and has to be taken into account. In this p ...

Plasma isotopic effect on the damping rate of toroidal Alfven eigenmodes with intermediate toroidal mode numbers

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard, Theodoros Panis

This paper reports on the results of recent experiments performed on the JET tokamak on toroidal Alfven eigenmodes (TAEs) with toroidal mode number (n) in the range up to vertical bar n vertical bar = 7. The stability properties of these medium-nTAEs are i ...

Production of long bunch trains with 4.5 mu C total charge using a photoinjector

Daniel Egger, Öznur Mete

A photoinjector, PHIN (PHotoINjector), has been realized at CERN by a joint effort of several institutes within the European Coordinated Accelerator Research in Europe program. The test facility has been installed and commissioned at CERN with the aim to d ...

Analysis of Defective Interconnections of the 13 kA LHC Superconducting Bus Bars

Luca Bottura, Pier Paolo Granieri

The interconnections between Large Hadron Collider (LHC) main dipole and quadrupole magnets are made of soldered joints of two superconducting cables stabilized by a copper bus bar. The 2008 incident revealed the possible presence of defects in the interco ...
