104 and opposite to the carbon dioxide laser 111 was a metal plate forged from 2024 aluminum painted black and measured 12 7 cm u00d7 15 24 cm u00d7 1 905 cm the metal plate 109 had one straight internal channel 0 635 cm in diameter through which water is circulated using a water pump the metal plate 109 was oriented with respect to the rest of the assembly so that any part of the laser beam 107 not being intercepted by the optical fiber 104 impinges on the water channel within aluminum plate 109 fused quartz substrates were invisible to the pyrometer 106 the carbon layer application in a second preferred embodiment is carried out in the same way as that in the first preferred embodiment except in the following aspects the beam 107 from the 25 w continuous monochromatic laser 111 is split into three beams instead of four as depicted in fig1 the hydrocarbon gas blown onto the heated deposition site 721 is butane with the same purity as the propane used in the first preferred embodiment the initial preset temperature at the deposition site is between 1375 and 1500 k the inner compartment 115 of the base 113 is not centered within the base 113 while not centered in the base 113 the inner compartment 113 is still axially surrounded by the outer compartment 116 a hermetically sealing silicon carbide layer 514 is applied to a microchip assembly 1360 comprising a superconductor microchip 1363 pressed between a first silicon wafer 1361 and a second silicon wafer 1362 by the process as illustrated in fig1 and 10 the top surface of the base 113 has a central nozzle 105 and an outer nozzle 102 with diameters of 4 2 and 52 3 mm respectively the outer.
