Abstract Until 1997, all the fibres used in the TILECAL prototypes were mirror aluminized in the opposite end to the readout side. This operation was performed always in the Swiss enterprise Precitrame, with the Magnetron Sputtering technique [1]. Before the aluminization, the fibres are cut and then polished in the Swiss enterprise Gebex. Bicron fibres were used to re-equip half of the Module 0 in 1998, the aluminization of these fibres was performed in Precitrame as in the previous years. The S250 Pol.Hi.Tech fibres were used to re-equip the other half of the Module 0, the aluminization was performed in an Italian enterprise by Cold Plasma Technique in a high vacuum environment. This note reports on: • The quality control of the Kuraray Y11(200)MS fibres for the 1997 Extended Barrel Module 0, table 1, performed in April 1997. The light output and effective attenuation length were measured, as well as the fibre to fibre fluctuations. To...
