Hello Nick,
I have the very same problem. I'm working too on a Hamamatsu photon-counting PMT and I'd like to keep the 1 ns rising time. This post is one year old and I'd like to know if you made it!
Anyway I share some information I have. I recommend you a paper "Amplifiers for use with photomultipliers - who needs them? -A.G. Wright" The key word is Transimpedance amplifier. I will purchase the OPA633 I think the most important features are the bias current and the gainbandwidth product, I need a 500 gain.
Hope to hear from you guys.
