Re: [Discuss-gnuradio] GnuRadio in particle accelerators

[M Dammer]

I thought about other options for signal analysis (KST for example). My
initial idea was in absence of a scintillation counter system to use a
(simple) PIN diode like the widely used BPW34 photodiode as detector.
There is some material about this on the web. Then put some amplifier
behind it and do the data acquisition with a DC to HF (direct sample)
modded RTL-SDR dongle. The interesting parameter in this case would be
the pulse height.
