Abstract: | Low-pressure mercury lamps are commonly used for germicidal applications such as water and wastewater sterilisation. The germicidal
effect is due to the emission of light at 254 nm, which leads to the destruction of most waterborne bacteria. The Microwave
plasma ultraviolet lamp (MPUVL) is a new technology for generating a high intensity ultraviolet (UV) light. A Fluorescent
optical fiber based sensor is presented which is used for monitoring the output of a high power microwave UV light source
and its control. This sensor is a fiber which has had its cladding removed and been coated with a phosphor doped polymer.

Japan. |
