I am inexperienced and need advice.
I have a solid state detector (an active component comprised of a P-type doped silicon semiconductor junction) simply diode. It has a BNC connector at the end.
The project is to connect the detector to a preamplifier then to Arduino ono with LCD reading in order to count an external photon beam from a linear accelerator.
I need your advice please.
MY advice is for you to explain what type of advice you think you need! Are you needing to power your system? Are you needing to write programs? Are you wanting someone to build and program something for you?
Please post a link to the product page or data sheet for the detector.
Morning Paul, Let's start with the list of components I've got so fare:
R4, or R3 (or earlier)? They are quite different!
So what output will that give to the Arduino?
What have you tried so far? Where are you stuck?
Do you have any experience with writing Arduino programs (known as "sketches")?
Do you have any experience with writing programs in general?
We need to know this to understand what level of advice you need.
EDP-15 3G:
15 mm water equivalent build-up, primarily designed for use in 6 to 12
MV beams.
I cannot find the datasheet but copied the following details from the user's guide
Arduino uno R3, No experience at all but I am determined to get there.
So start with the basics - don't try to leap straight into something advanced!
Basics:
The key is to take one step at a time - don't try to do everything all at once.
Start basic, and build up.
All appreciated. I have just downloaded sketches and working on it. Will keep you updated
What's the pulse frequency out of your photon detector? Is it an avalanche photodiode perhaps?
This happens in the depletion zone. When radiation beam interact with the detector, electrons from the n-type migrate across the junction between the two layers to fill the holes in the p-type, creating a depletion zone or charge zone if you want.
This depletion zone behave like the detection area of the diode. Radiation interacting with the atoms inside the depletion zone causes them to re-ionize, and create an electronic pulse which can be measured.
Sorry, that is completely useless.
You will need some sort of amplifier/interface. I imagine the manufacturer sells one.
If it is a SiPM, this thread may be of interest.
OK, but again, what's the output frequency? I've worked with photomultiplier tube detectors that produce hundreds of MHz pulse output even at low light levels. Arduino is not going to read that.
