GENIETS TRAGEDIE: ET TSJEKKISK SKUESPILL OM HAMSUN

This article discusses the play The Old Nazi: The Tragedy of a Genius, written by the Czech journalist Martin Komárek and staged in Prague in 2010/2011. It presents both the formal and the thematic aspects of the drama and argues that this unique text deserves to be known outside of the Czech Republic. Komárek made himself familiar with various information about Hamsun’s life, but this did not curb his imagination; his play works very well as theater. The drama contains many fictitious events and dialogues, yet at the same time, it does not distort in any major way the historical image of Hamsun. The play is thus well balanced and provides a very good basis for potentially successful theater productions

Thermal Loading Considerations For Synchrotron Radiation Mirrors

Grazing incidence mirrors used to focus synchrotron radiation beams through small distant apertures have severe optical requirements. The surface distortion due to heat loading of the first mirror in a bending magnet beam line is of particular concern when a large fraction of the incident beam is absorbed. In this paper we discuss mirror design considerations involved in minimizing the thermal/mechanical loading on vertically deflecting first surface mirrors required for SPEAR synchrotron radiation beam lines. Topics include selection of mirror material and cooling method, the choice of SiC for the substrate, optimization of the thickness, and the design of the mirror holder and cooling mechanism. Results obtained using two-dimensional, finite-element thermal/mechanical distortion analysis are presented for the case of a 6/sup 0/ grazing incidence SiC mirror absorbing up to 260 W at Beam Line VIII on the SPEAR ring. Test descriptions and results are given for the material used to thermally couple this SiC mirror to a water-cooled block. The interface material is limited to applications for which the equivalent normal heat load is less than 20 W/cm/sup 2/
