Abstract (en)

Photomultiplier tube comprising a photocathode (10), focusing electrodes (12,12') and a focusing multiplier structure (20), of large entrance area relative to the photocathode and comprising, at least, one entrance dynode (21). According to the invention, the said photomultiplier tube possesses, between the photocathode (10) and the said focusing multiplier structure (20), a first multiplier stage (30) composed, in order starting from the photocathode (10) and focusing electrode (12,12') assembly, of a grid (31), of a multiplier dynode (32) of the perforated-plate type, and of an exciter grid (33) provided with the same arrangement of perforations as the said first multiplier dynode (32), the output of the exciter grid (33) being coupled to the said entrance dynode (21) of the focusing structure by a focusing electrode (40). <??>Application to photomultiplier tubes. <IMAGE>
