New implosion tests of the PMTs of the Hyper-Kamiokande telescope in collaboration with SOCIB

The sixth implosion test campaign, led by the LSC and carried out at the SOCIB facilities (Mallorca), has recently been successfully completed. These campaigns aim to validate the viability of the protective covers of the sensors of the future HK telescope.

This time, thanks to the work of a team of 20 people after 3 weeks with a total of more than one tonne of steel mobilised and 50 photomultipliers tested, it has been confirmed that the Spanish prototypes are suitable for operating in conditions equivalent to those of the telescope, i.e. at a depth of  70 m underwater.
