Tile PMTs, developed over 15 years, faced challenges but met TileCal specifications. Starting with APDs in RD1, the journey involved collaboration with Hamamatsu for revolutionary R5600 PMTs. Main R&D improvements each year led to the creation of PMTs meeting TileCal needs. Key specifications for Ti
