dc.description.abstractHF CVD (hot filament chemical vapour deposition) reaktor je technologické zariadenie, v ktorom sa na rôznych substrátoch syntetizujú uhlíkové nanorúr ky. Reaktor pracuje na princípe pyrolýzy metánu a vodíka. Substrát je umiestnený na molybdénovom držiaku niekoľko milimetrov pod žeravenými (2200 °C) volfrámovými vláknami a jeho teplota počas syntézy je optimalizovaná cca na 600 °C. Merania a regulácie teploty rotačného držiaku v priebehu syntézy sa vykonáva teplomerom s bezdrôtovým optickým prenosom dát. Počas prevádzky zariadenia sa v yskytol závažný probl é m, a to nestabilné napájanie, čo viedlo ku kolísaniu teploty v reaktore. To je dôvod, prečo bolo navrhnuté iné riešenie za použitia impulzného napájacieho zdroja. Merací reťazec bol zjednodušený od stránením mobilných kontaktov a izolačných zosilňovačov, ktoré po prehriatí pracovali ne s p r ávne a skresľovali údaje o teplote. Výsledkom tejto práce je návrh a rekonštrukcia obvodov napájajúcich merač teploty v HF CVD reaktore.sk

dc.description.abstract-translatedHF CVD (hot filament chemical vapour deposition) reactor is a technological apparatus in which carbon nanotubes are synthesized on various substrates. The reactor operates on the principle of pyrolysis of methane and hydrogen. The substrate is placed on a molybdenum holder, several millimetres below hot (2200 °C) tungsten filaments and its temperature during synthesis is optimized to approximately 600 °C. Measurement and control of the temperature of the rotating holder during synthesis are carried out by a temperatur e gauge with wireless optical data transfer. During operation of the facility a severe drawback was encountered, namely instable supplying resulting in temperature fluctuations in the reactor. This is why another solution has been designed utilizing a swit ched mode power supply. The measurement string has been simplified by removing mobile contacts and isolation amplifiers that behaved incorrectly – when they became overheated – and distorted the data on temperature. The result of the present work is the de sign and reconstruction of the circuitry supplying the temperature meter in the HF CVD reactor.en
