A laser produced Sn plasma driven with a pulsed CO2 laser and emitting EUV radiation has been generated in a magnetic field of 0.5T. The multiple-ionized plasma ions are efficiently guided along the B field lines of the double coil magnet. The neutral Sn atoms and Sn clusters, however, expand freely inside the vacuum chamber and contaminate e.g. EUV optics. We therefore evaluated ECR heating of...

We determine simple analytical conditions for combined radiative and thermal equilibrium between the X-ray emitting plasma and cold reprocessor in active galactic nuclei (AGN) and galactic black holes (GBH). These conditions determine the pressure at the transition zone, which is not arbitrary in the static situation. The conditions for static solution are derived analytically for different for...

Objective: Pili (Canarium ovatum, Engl.) pomace is an underutilized agricultural waste that possesses great potential to be regarded as a functional food ingredient. The aim of this study was to measure the polyphenol content and antioxidant activity of pili pomace drink and determine the influence of heating on these parameters. Moreover, it sought to assess the acute effects of thermally proc...

In the burning fusion plasmas of next step devices such as ITER (2001 ITERFEAT Outline Design Report IAEA/ITER EDA/DS/18 (Vienna: IAEA) p 21), the majority of the heating of the fusing fuel will come from the plasma self-heating by fusion born α-particles. Recent advances in theoretical understanding, together with the development of new diagnostic techniques, make this a timely opportunity to ...

A new technique is described for the isochoric heating (i.e., heating at constant volume) of matter to high energy-density plasma states (>10(5) J/g) on a picosecond time scale (10(-12)sec). An intense, collimated, ultrashort-pulse beam of protons--generated by a high-intensity laser pulse--is used to isochorically heat a solid density material to a temperature of several eV. The duration of he...

Radio-frequency (RF) power in the ion cyclotron range of frequencies (ICRF) has been chosen as the primary auxiliary heating technique for BPX. This decision is based on the wide success of ICRF heating in existing large-scale experiments (JET, TFTR, JT-60), the capability of ion cyclotron waves to penetrate the high-density plasmas of BPX, the ability to concentrate ICRF power deposition near ...
