R2386 is a 28mm (1-1/8 Inch) diameter, side-on photomultiplier tube having a trans-
mission mode multialkali photocathode. The transmission mode photocathode off-
ers better spatial uniformity and wider angle of radiation input than conventional
side-on tubes which have opaque photocathodes (reflection mode photocathode).
Also, this type of photocathodes is independent of polarized light.
The R2368 has a 9-stage dynode which provides high gain and employs an HA
Coating for noise reduction and an "Anti-hysteresis design".
