An apparatus for generating electricity via thermophotovoltaic (TPV) energy conversion is described. High efficiency is obtained by introducing a material into a combustion chamber that emits bright near-monochromatic visible light upon heating. This light is then directed to fall on an array of photovoltaic (PV) cells which convert the light to electricity. Heat and infrared radiation that is not absorbed by the PV cells is returned to the combustion chamber to further improve conversion efficiency.

Particulate deposition rate on a photolithographic mask, particularly of tin (Sn) particles produced within an EUV light source, is reduced by producing turbulence within a radiation source chamber of the EUV light source. Turbulence can be produced by changing the temperature, pressure, and/or gas flow rate within the radiation source chamber. The turbulence reduces the number of particles exiting the EUV light source which could be deposited on the photomask.

Interstitial brachytherapy is a cancer treatment in which radioactive material is placed directly in the target tissue of the affected site using an afterloader. The accuracy of this placement is monitored in real time using a urinary catheter that locates the radioactive material according to the radiation levels measured by sensors in the walls of the urinary catheter. A scintillator that is embedded in the walls of the urinary catheter produces light when irradiated by the radioactive material. This light is proportional to the level of radiation at each location. The light produced by each scintillator is carried through optical fibers and then converted to an electrical signal that is proportional to the light and the radiation level at each location. The radioactive material is located according to the plurality of electrical signals. This location can be used as quality control feedback to the afterloader.
