In the coming years, the LHC (Large Hadron Collider LHC) at CERN will increase its luminosity by an order of magnitude, reaching unprecedented levels of radiation, to become the HL-LHC (High Luminosity Large Hadron Collider). Due to the damage threshold of silicon detectors currently used to determine the particle trajectories, the operation of HL-LHC requires a new generation of sensors resistant to such influences. In this sense, the CERN RD50 Collaboration has launched an intensive research program to develop new detectors with high tolerance to radiation.

A year ago, the Laser SGIker Service collaborates with researchers from the CSIC-UC, University of Sevilla and CERN in the development of a new technique for the characterization of silicon detectors of the LHC, based on photon absorption of ultrashort pulses. Last November, some details of the experimental system implemented in the UPV/EHU and the first results obtained were presented at the 25th RD50 Workshop at CERN (Geneva). Given the good acceptance of the technique in this event, is expected to intensify collaboration next year 2015.
