Study of Radiation Hardness Photomultiplayers
Protvino, 1996.- p.4, figs 2, refs.:5.


The radiation hardness of PMP FEU-115 with the photocathode windows from glass S096-1, dynode systems of alloyed type and PMP windows of $MgF_{2}$, radiation hardness glass S096-1, glasses S096-1, S050 is studied. It is shown that there are no registered changes in photocathode S096-1 windows transparency up to 35 Mrad, PMP FEU-115 output signals --- up to 15 Mrad and alloyed type dynode system amplification --- up to 100 Mrad.
