AGFA ADC 5155 X-ray Scanner Teardown (4 part series)
« on: November 18, 2020, 08:47:27 PM »
Part 1: AGFA ADC 5155 System teardown
Teardown of a AGFA ADC 5155 x-ray image scanner / digitizer. Also known as Computerized Radiography (CR) it fulfills the job of scanning a x-ray exposed image plate with a laser beam and extract each pixel illumination with a photo multiplier tube setup.

This particular unit has a very interesting computer that runs on VME framework developed for the Motorola 68000 series CPUs.

This is the reverse engineering and teardown of a very interesting computer that runs on VME framework developed for the Motorola 68000 series CPUs. It runs a custom operating system called Monitor 4.28 developed by Agfa-Gevaert NV, Belgium.

Teardown of the laser scanning module that feeds in the image plate and converts the irradiated plate from analog pixel values to digital bits through a photomultiplier tube.

Teardown of the photomultiplier tube assembly (PMT) and its high voltage power supply. The high voltage power supply and PMT is reverse-engineering to use the PMT as a cosmic ray detector with a scintillation plastic crystal in front of the PMT.

/>
The PMT assembly contains a Burle S83021E photomultiplier tube


The Heim Electronic SNP1.5N24/176 high voltage power supply is a custom made AGFA unit that can output a maximum of -1.5kV / 6mA. It is a very nice little power supply that only takes 24VDC supply, can be controlled by 0-10V and gives a feedback at 0-10V.





The low output voltage makes a huge difference on the sensitivity of the PMT, at its -600V it is   20 times less sensitive than if it was running at -1100V.



Some examples of the detected particles resulting pulse on the oscilloscope

Nice experiment, as I said on youtube, it's always nice to find something that uses only single digital flags and analog signals which makes it pretty easy to reuse.  :)

Where did you get your Scintillation platic?
I'm searching for some as well, maybe some Bicron BC412.
Do you know some place in europe that sells stuff like this?


Greetings,
Michael

I could only find a note that I bought the 2" diameter round one for around 80€, so I guess it was from USA as that total would include shipping and import taxes. Seems to fit with current listing prices on ebay.

The unknown square piece was given to me by a friend that works with radiography.

Thanks for the response, I guess I will have to order it from the USA as well.  :D
