Thread: Translate an old datasheet

Hello all you people out there!

I have an old Datasheet from a photomultiplier tube (It collects and amplifies photons) that is written in russian.
Unfortunately i do not know any word in the russian language. I searched for a translation forum and found this.
Maybe you could help me?

Thank you!

My attempt (the red stuff I didn't get):

Photoelectric multiplier FEU-35 - for operation in gamma spectroscopy and scintillation counters. Photoelectric multiplier FEU-35A - for operation in scintillation counters to detect weak X-ray radiation in wavelength range 0.05-0.25 nm.
Photocathode - antimony-caesium, spectral characteristic No. 6. Optic entrance - торцвой. Diameter of operational area of cathode - 25 mm. 8 amplification cascades. Glass mounting with base. Mass - 50 grams.

Principal data

range of spectral sensitivity, nm
range of maximal spectral sensitivity, nm
photocathode sensitivity, microA/lm
anode sensitivity, A/lm
. with feed voltage = 0.7 kV
. with feed voltage = 1.2 kV
. etc
Dark current (with anode sensitivity 10 A/lm ), A
Anode current, microA
Feed voltage, kV
Lifetime (with feed voltage 1.25 kV), hours
Критерий оценки
. anode sensitivity (with feed voltage = 1.25kV for FEU-35 and feed voltage 1.6kV for FEU-35A), A/lm


Standard circuit of voltage splitters FEU-35, FEU-35A. Voltage splitter is uneven: R1=2R;R8=R9=1.5R;R2-R1=R < 100 kOhms. Capacitance C< 0.05 microF.

I - to photocathode; II - to dynodes; III - to anode; IV - to load; V 0 to feed source.

It means that photons should come from the flat end.
