[Solid_tof] SoLID TOF requirement

[Alexandre Camsonne]

How much charge can one usually get from a MCP PMT and what is typical gain
? We might need to run at lower gain and amplify because of background and
that could reduce also the timing performance. Also what is pulse width for
mRPC and MCP PMTs ? I guess for readout we would need DRS5 or PSEC5 to be
able to deal with pile up and reach 200 KHz trigger rate.
