Definitions

  • Central pipe 12 serves to supply cooling water to volume 14. This cooling water flows out of pipe 12 near remote end 26 of volume 14, flows back along inner quartz cylinder 16 and sleeve 15, and leaves lamp 10 through outlet pipe 50.
  • the liquid being treated enters the lamp through housing input pipe 52, flows along and around the outside of outer quartz cylinder 20 as it is irradiated by the ultraviolet radiation generated by the excimer discharge within excimer gas enclosure 18, and exits the lamp through housing outlet pipe 54.
  • the lamp appears electrically as a series of five dielectrics between the electrical inputs formed by pipe 12 and housing 28.
  • cooling liquid feed path and return path to central pipe 12 are long enough and the impedance of the cooling liquid high enough, such liquid flow paths will merely act as high impedances in parallel with the lamp, and the load they cause on the power supply will be inconsequential.
  • typical tap water has a resistivity in the range of 20 to 200 micromho, and therefore has a resistance of 150 kilohm to 1.5 megohm per foot when flowing in a .45 inch diameter plastic hose. It is then only necessary to determine what leakage current would be tolerable for power supply 60 and to make feed hose 62 for pipe 12 and return hose 64 long enough to limit the leakage current to that value.
