Measures towards Increasing the Effectiveness of Research in the Field of Chemical Synthesis
Václavík, Jiří ; Hartman, Ladislav (advisor) ; Koubek, Josef (referee)
Research in the field of chemical synthesis is a very diverse and complex activity. Individual workplaces differ in many aspects and this essentially impacts the productivity. The aim of this Master's Thesis is to identify, name and analyse those aspects, and to suggest measures to be taken in order to help increase the performance, all that within defined assumptions. The first half of the Theoretical Part is devoted to academic studies on this topic, which are mainly focused on the HR part. Selected methods of lean manufacturing commonly used in industry are also described. The Experimental Part comprises an analysis of research facilities in which the author worked as a chemist, and a set of proposed measures that lead to an increased productivity. The Thesis is concluded by a demarcation of a series of factors that influence the performance of R&D workers, groups and institutions, and a vision of an ideal laboratory is presented.

Simulation of optical system of deposition controller
Doleček, Roman ; Pintr, Pavel ; Václavík, Jan
The report describes results of modeling of optical system which is component of optical monitoring system applied on machines for vacuum thin film deposition. Results were compared to real behavior of system, especially chromatic properties and total throughput. A numerical optimization, based on analysis results, was performed in order to improve throughput and ruggedness of the system.

Gallium Phosphide as a material for visible and infrared optics
Václavík, Jan ; Vápenka, David
Gallium phosphide is interesting material for optical system working in both visible and MWIR or LWIR spectral ranges. Number of a material available for these applications is limited. They are typically salts, fluorides or sulphides and usually exhibit unfavorable properties like brittleness; softness; solubility in water and small chemical resistance. Although GaP has do not offer best optical parameters excels over most other material in mechanical and chemical resistance. The article describes its most important characteristics and outlines some applications where GaP should prove useful

Photonometers for coating and sputtering machines
Oupický, Pavel ; Jareš, Daniel ; Václavík, Jan ; Vápenka, David
The concept of photonometers (alternative name of optical monitor of a vacuum deposition process)for coating and sputtering machines is based on photonometers produced by companies like SATIS or HV Dresden. Photometers were developed in the TOPTEC centre and its predecessor VOD (Optical Development Workshop of Institut of Plasma Physics AS CR) for more than 10 years. The article describes current status of the technology and ideas which will be incorporated in next development steps. Hardware and software used on coating machines B63D, VNA600 and sputtering machine UPM810 is presented.
