Michaëlsson's (1961) method for the measurement of plasma bilirubin concentration was found to be complicated by conjugated bilirubin. Delaying the addition of the accelerator, diphylline, corrected this fault. The method was calibrated using serum or plasma, since reconstituted protein solutions introduced large errors.
In this paper the results of measurements azimuthal component distribution plasma column magnetic field in coaxial accelerator PW-7 are presented. Registration was performed by probe method. The objective work is to investigate dynamics and temporal evolution field. It has been revealed that using a dielectric (quartz) tube limiting column, escape charged particles from discharge onto walls vac...
A new coaxial plasma gun is described. The long term objective is to accelerate 100-200 microg of plasma with density above 10(17) cm(-3) to greater than 200 km/s with a Mach number above 10. Such high velocity dense plasma jets have a number of potential fusion applications, including plasma refueling, magnetized target fusion, injection of angular momentum into centrifugally confined mirrors,...
Abstract The neutral beam injectors of the ITER experiment will be based on negative ion sources for generation beams composed by 1 MeV H/D particles. prototype these is currently under testing in SPIDER experiment, part Neutral Beam Test Facility Consorzio RFX, Padua, Italy. Among targets experimentation SPIDER, it foremost importance to maximize current density produced accelerator. operating...

These notes are intended to provide a brief primer in plasma physics, introducing common definitions, basic properties, and typical processes found in plasmas. These concepts are inherent in contemporary plasma-based accelerator schemes, and thus provide a foundation for the more advanced expositions that follow in this volume. No prior knowledge of plasma physics is required, but the reader is...
Recent electron beam driven plasma wakefield accelerator experiments carried out at SLAC indicate trapping of plasma electrons. More charge came out of than went into the plasma. Most of this extra charge had energies at or below the 10 MeV level. In addition, there were trapped electron streaks that extended from a few GeV to tens of GeV, and there were mono-energetic trapped electron bunches ...
A modified version of the plasma beat-wave accelerator scheme is proposed, based on autoresonant phase locking of the Langmuir wave to the slowly chirped beat frequency of the driving lasers by passage through resonance. Peak electric fields above standard detuning limits seem readily attainable, and the plasma wave excitation is robust to large variations in plasma density or chirp rate. This ...
