Laser-triggered electron source for x-ray applications

We report the results of the development of an electron source , based on the emission of electrons from plasma . The plasma electron source delivers emission currents of more than 1 A, based on a laser-induced discharge plasma and grid-controlled electron emission. Circuit times of less than 1 µs and temporal modulation strongly connected to laser burst duration were measured. X-ray imaging verified high brightness and low emittance of the electron beam

Effect of ionizing irradiation on the physiological activity of cyclic adenosinemonophosphate on smooth muscle preparations.

The effect of ionizing irradiation on the physiological activity of cyclic adenosine monophosphate (cAMP) in smooth muscle preparations from frog lung was studied. cAMP, given as dibutyryl salt (dib-cAMP) inhibited the radiation induced contractions of the muscle in a manner similar to the action of theophylline. In vitro irradiation of dib-cAMP resulted in an alteration of the chemical structure of this substance, i.e., formation of monobutyryl-cAMP and further derivatives as well as a decomposition of the purine structure. There was also a loss of the relaxing activity of irradiated cAMP on the muscle tone of frog lung preparations. The physiologically measured inactivation of dib-cAMP was far more pronounced than the chemical alteration. An inhibitory effect of the reaction products is postulated

SLIOS: a contribution to standard procedures in stray light measurements

Light scattering measurements are important tools for characterizing optical surfaces can basically be divided into two main groups: total scatter measurements (TS) and Angle Resolved Scattering (ARS). Since TS measurements are fairly straight forward and widely used, international standardization has formulated an international draft standard on it, ISO/DIS 13696. ARS is a more complex method and not as common as TS measurements. However ARS data in form of the Bi-directional Reflectance Distribution FUnction (BRDF) can be used to predict stray light in Laser and Industrial Optical Systems. Because of increasing importance of this topic the EC is sponsoring a project regarding 'Standard procedures for stray light specification, measurement and testing - SLIOS'. During the project two of the activities are: performing a round robin experiment of measuring BRDF data at 5 different sites including some complementary techniques; compiling of an open access data base of measured BRDF data, measured according to procedures agreed upon between the SLIOS partners and proposed for 'Standard Procedures'. Results of these two activities will be presented
