Abstract
We investigated the darkening of two high
OH
-
content quartz fibres irradiated with 24
GeV protons at the Cern PS facility IRRAD. The two tested fibres have a 0.6
mm quartz core diameter, one with hard plastic cladding (qp) and the other with quartz cladding (qq). These fibres were exposed at about 1.25
Grad in 3 weeks. The fibres became opaque below 380
nm and in the range 580–650
nm. The darkening under irradiation and damage recovery after irradiation as a function of dose and time are similar to what we observed with electrons. The typical attenuation at 455
nm are
1.44
±
0.22
and
2.20
±
0.15
dB
/
m
at 100
Mrad for qp and qq fibres, respectively. The maximum damage recovery is also observed near this wavelength.
