Photonics and Web Engineering: WILGA 2009

The paper is a digest of work presented during a cyclic Ph.D. student symposium on Photonics and Web Engineering WILGA 2009. The subject of WILGA are Photonics Applications in Astronomy, Communications, Industry and High-Energy Physics Experiments. WILGA is sponsored by EuCARD Project. Symposium is organized by ISE PW in cooperation with professional organizations IEEE, SPIE, PSP and KEiT PAN. There are presented mainly Ph.D. and M.Sc. theses as well as achievements of young researchers. These papers, presented in such a big number, more than 250 in some years, are in certain sense a good digest of the condition of academic research capabilities in this branch of science and technology. The undertaken research subjects for Ph.D. theses in electronics is determined by the interest and research capacity (financial, laboratory and intellectual) of the young researchers and their tutors. Basically, the condition of academic electronics research depends on financing coming from applications areas. During Wilga 2009 there were organized, and thus the paper debates, the following topical essions concerning applications of advanced electronics and photonics systems: merging of electronic systems and photonics, Internet engineering, distributed easurement systems, security in information technology, astronomy and space echnology, HEP experiments, environment protection, image processing and iometry. The paper contains also more general remarks concerning the workshops organized by and for the Ph.D. students in advanced photonics and electronics systems. WILGA Symposium used to have several dedicated sessions on EU FP6 CARE Project and now on EU FP7 EuCARD Project. Papers are presented on E-XFEL, FLASH, accelerator timing, LLRF systems and criosystems.
