Abstract
Quartz glass sleeves containing medium-pressure mercury
lamps (MPLs) are subject to radiation damage due to the
intense VUV- and UV-C emission of this kind of lamp.
In general sleeves are made out of conventional quartz
glass produced by melting pegmatite sand under reducing
atmospheric conditions. The result is a “dry” quartz
glass material with low OH-content and a large amount
of SiH groups, which are subject to strong radiation
damage reducing the UV-transmission and useful lifetime
of the sleeves. Alternative materials containing SiOH in
addition to SiH groups are much more resistance against
radiation damage showing a self-annealing property under
prolonged irradiance.
