Re: APD Voltage Settings

Hi Peter,

I did not go beyond 450V, but I got this number by looking
at the OUTPUT of the diode + preamp.  Of course this output
depends on the signal driving the photodiode.  I tried to keep
the output signal below 5V. Using my light source I didn't
need to go above 450V for any apd/preamp.   I think that
with a weak enough light source driving the APD you can go
higher.

I do not yet know the specific model number for our APD/
preamp, otherwise I would look it up.  I've been waiting for
our group's post-doc to send me this information, but he
is very busy.  I will remind him of this tonight.  Hopefully the
documentation will address the issue of a maximum voltage.

Thanks,
John

Dear John,

Forget the Molex connector. Penny sent the package
already this morning.

Thanks
