Characteristics: The UV filter sleeves are used to filter the Ne lamp lights. The light transmittivity of the plastic cover of the lamps has been analyzed at the CERN Chemical laboratory, showing a good transmission starting from 280 nm. The wavelength between 260 nm and 400 nm are potentially dangerous for the scintillating tiles and for WLS fibres. It has been decided to investigate if there is a way to filter the light and reduce the transmission of the dangerous wavelengths. A quick investigation on the WEB spotted out this UV filter sleeves that are available for a reasonable price ($ 6.75/each). Contacts with the producer are going on.
Quantity: 20 sleeves are sufficient, some spares are envisaged.
Procurement:
23/March/1999 30 UV Filter Sleeves have been ordered.
Schedule for delivery: According
to the instrumentation plant schedule.
