Idea for an add on for pi detector

[Sean_Goddard]

One of my projects is an R&D PI using direct sampling with an 18-bit ADI Pulsar ADC. My experience is that sampling a traditional PI decay curve does not offer much benefit for advanced analysis. So we are looking at significantly different PI waveforms. I can't really divulge what they are, but one is easy to guess.

"You can ring my coi - oi - oil....ring my coil" tra la la la? Now I KNOW this method works.

Funny you say there is no information in the decay curve Carl, as I observed the opposite (maybe my results were flawed) but I saw Iron, SKEW the decay curve to the RIGHT (zero point) and Gold/ Silver etc skew to the LEFT, what I mean is what appeared was as though you were ROTATING the curve about a point somewhere in the middle (this was my oscilloscope trigger setpoint with pre-record and delay set up) If an array of PRE samples were taken and POST samples (centre curve REFERENCE point) then you could "curve fit" using a micro and reference curves (I Know this method works too) as this is what the PD3200 and PD3600 did. I have one...THEY WORK VERY WELL, except when the target is deep and small, but then they are PI's so go MUCH deeper anyhow!
