2014 A pulsed source for Cs-ions has been constructed as part of a sputter ion source in Hortig geometry. A beam of Cs-ions is extracted from a tungsten surface ionizer and bunched into pulses a few ns wide by a combination of velocity and path-of-flight modulation. It is expected that such a beam will produce intense pulses of negative ions having pulse widths in the ns range. REVUE DE PHYSIQU...

Progress in construction and scaling of a repetitively pulsed, flash x-ray device producing intense nanosecond pulses is described. This source would be used to excite nuclear fluorescence for the evaluation of candidate materials for a gamma-ray laser. For some applications these devices can offer a table-top laboratory alternative to laser plasma x-rays and to synchrotron radiation.

UNLABELLED STUDY DESIGN/BACKGROUND AND OBJECTIVES: Currently, ablative laser therapy (with CO2/Er:YAG lasers) is considered an effective and promising method of skin rejuvenation. The induction of collagen synthesis was observed after treatments with the CO2 laser and with the long-pulsed Er:Yag laser. In past years, the undesirable side effects and risks of these methods have led to intensifie...

Two new technologies for use in the food industry are described. The first method discussed uses intense pulse of light. This pulsed light (PureBright) process uses short duration flashes of broad spectrum "white" light to kill all exposed microorganisms, including vegetative bacteria, microbial and fungal spores, viruses, and protozoan oocysts. Each pulse, or flash, of light lasts only a few h...

Background and Objectives: Hair removal is a common aesthetic concern for patients referred to dermatologists physicians. Lasers lights are one of the mainstays in management this condition. Among these devices, intense pulsed (IPLs) broadly used order reduce number width hair present. Currently techniques associated with high risk side effects, such as hyper or hypopigmentation.
