Ok guys. Here comes the next episode of how figure out (hack) the signal of the Rigaku scintillation tube probe.
First of all, this is NOT a standard "universitary" scintillation probe, where the original photo multiplier signal goes directly on the signal cable. This is a scintillation probe with an integrated pre-amplifier inside!!
(Which is the type of scintillation probe type you want, to process a raw signal in some kind of hacking approach.)
On left side you see the voltage divider. On the right side you the little preamplifer board.
Let's have a closer look at the out pins of the preamplifer board, now.
To keep it simple and stupid, I am simply labeling the external pins of the preamplifier board from left to right
- A: light blue
- B: orange
- C: white
- C: dark blue + thin black
- E: another black connected to the ground of the high voltage cable
The original signal from photo multiplier tube is another (sixth) pin F not visible in the photo.
Third, let's have a closer look on the 5 pole cable, now.
The cable contains
- light blue
- thick black, which contains white + dark blue inside
- thin black (which is unvisible in the opposite perspective)
The big red cable is the high voltage cable, which is connected to the BNC plug.
Last for completeness only, a look at the 5-pin connector again (which already has been posted before)
On the left you see the high voltage BNC plug. On the right you see the - much more interesting - the 5-pin connector, which is the end of the 5 pole cable in the previous photo.
Happy guessing on which cable has which electrical assignment now.
Some thoughts from me:
