DIY Magnetron Sputtering Chamber

This project might be of interest to some of you. As part of a larger project I need to apply a thin conductive film to some CZT crystals and for that I need a vacuum deposition system. I found a few old systems on eBay for around US $3500 that were either broken or for parts only, so I decided to m...

Re: Looking for XRF comparison and calibration software recommendations

Ed,

Check out a site called PeakaBoo - open source software for XRF. I am interested in this too, but currently working on the detector side of things.

Re: Hello from New York

Ed,

I am obviously positively biased towards the GS-PRO-V5 (pun intended) , it has a built in texas Instruments sound card.

Unless you have unlimited resources my advise would be to focus on the probe (detector) that's where you can make the biggest gain.

Re: Hello from New York

Hello Ed, Welcome to the forum... Building an XRF setup is in theory not so hard, but the problem we come up against is to find a low energy detector with good resolution. Under 50 KeV energy the pulse height from any detector is small and consequently the resolution is poor, which makes it hard to ...

Re: Software for embedded system (ESP32 "arduino")

Nice job,

Many years ago I was also playing around with an Arduino, I made this budget version of a spectrometer.

It was just a fun project and a completely useless display.

Re: The New GS-PRO-V5

Hi Guys, This is a very old thread - If you own a GS-PRO with a white circuit board the only likely fault is a dead opamp (LM6142) it can be replaced without soldering for around $4.50. When both Shape and Volume potentiometers are turned up to maximum it sets up a condition where a large pulse will...

ImpulseQt v3.2.5.0

While testing impulse with a synthetic pulse which has a resolution of 0.2% I noticed a slow but steady peak drift to the left. The drift was slow - only around 1 channel in 4000 every 30 seconds, but because it appeared constant I decided to investigate - Was it the synthetic pulser drifting or was...
