REACTOR SYSTEM FOR GROWTH OF CARBON BASED NANO MATERIALS. THE SYSTEM IS COMPUTER CONTROLLED AND INCLUDES AS HEATER, SHOWERHEAD, MASS FLOW CONTROLLER AND POWER SUPPLY. SAMPLES ARE PLACED ON THE HEATER AND ARE EXPOSED TO GASES DISTRIBUTED VIA THE SHOWERHEAD. DURING GROWTH A HIGH VOLTAGE IS ALSO APPLIED BETWEEN THE HEATER AND THE GAS SHOWERHEAD TO FORM A PLASMA. THE TEMPERATURE OF THE SAMPLES IS DETERMINED EITHER BY CONTACT THERMOCOUPLE OR BY PYROMETRY. THE FLOW OF THE GASES, TYPICALLY CONSISTING OF CARBON CONTAINING GAS, REDUCING GAS AND AN INERT GAS IS CONTROLLED BY MASS FLOW CONTROLLERS. A POWER SUPPLY IS USED FOR THE PLASMA. THE SYSTEM IS USED FOR RESEARCH AND IN INDUSTRY.
