In this study, two-phase immiscible polymer blend with selective radiation heating by infrared laser is studied numerically. The phase-field model of a non-isothermal flow, which accounts for laser induced temperature field, two-phase flow with interfacial tension and Marangoni effect, was developed. This model was used to simulate a droplet deforming in shear flow with various shear rate, droplet size and laser irradiation power. Based on the simulation results the effect of the selective radiation heating by infrared laser to the droplet deformation, the break-up situation and the micro-structure of the polymer blend was discussed. The paper concludes with suggestions for future research and potential applications.

WP10 is one of the working packages of the HiPER project and it has the goal of addressing, in a systematic and programmatic way, some of the key experimental uncertainties on the way towards fast ignition (and shock ignition) in a perspective of risk reduction, so to contribute to the definition of the basic characteristics of the HiPER project. The paper describes the key points contained in the short term HiPER experimental road map, as well as the results of two first experiments performed in "HiPER dedicated time slots" in European Laser Facilities. © 2010 American Institute of Physics.

HTS leads are increasingly used on superconducting magnets. In most cases the magnet leads are shielded from the magnetic field by iron or the magnet is actively shielded, so that the stray field at HTS leads is low. There are magnets where the HTS leads must be located in a magnetic field. The two general types of HTS leads that are commercially available are either leads fabricated from bulk HTS materials or leads fabricated from oriented HTS materials that have one or two planes of favorable current density. This paper will discuss how two types of leads are affected by magnetic field. The warm end temperature of the HTS lead is a key lead performance factor. © 2008 American Institute of Physics.

The first successful experimental studies of microwave radiation from a co-axial Free-Electron Maser (FEM) based on two-dimensional (2D) distributed feedback have been recently conducted. This paper contains a description of the experimental set-up and the results obtained. The high-power pulsed power supply and high-current accelerator (HCA) developed and used to drive the FEM are discussed. The results of the experimental study of the FEM operating in the Ka frequency band are presented and compared with theoretical predictions. © 2005 American Institute of Physics.
