Electronics, Detectors and Radiation analysis

Recently I have bought a Ludlum Model 3 because I wanted a professional meter that can drive scintillation probes as well as geiger müller tubes. In this article I take a look at the functions and the build of the meter overall. There are various switches and a pushbutton on the device. The central rotary…

VEB Robotron “Otto Schön” Dresden was a manufacturer of electronical equipment in east germany (GDR). The scintillation probe I own was made by that company presumably in the 70s or 80s. It is very large compared to other detectors. It can be disassembled rather easy. There are only four screws holding everything together. The scintillation…

For plastic scintillators or scintillation crystals Recently I have bought a Ludlum Model 3 survey meter which supports geiger müller tubes and also scintillation probes. Since the one I bought only came with a Ludlum 44-7 pancake geiger müller probe, I could either buy one or build one by myself. Actually the original Ludlum scintillation…

10 Stage Photomultiplier Diameter: 38,8mmDiameter photocathode: 34mmTotal length: 108mmBase type: FE1112Peak sensitivity: 425nm I found this Photomultiplier to be a great choice for experiments like gammaspectroscopy and particle detection with several scintillators emitting in the blue spectrum. I bought ab Box of brand new (old) tubes from a very nice guy. They were supposed to…

This is a teardown of a STRATEC Scintillation probe. I bought this one used. It seemed to be in a great shape with no visible damages on the outside. The probe was made in the late 80s or early 90s. It was presumably used with a gamma spectroscopy unit. There are three connectors at the…
