Single electron non-perturbing detector
I am designing an experiment where I need to trigger the release of an electron by a radioactive source (Sr-90).
The easy way to do it is to use a thin scintillator right after the source collimator. ...

What is the smallest distance between a decaying vertex and an interaction point a detector can measure?
A short lived particle is created at the interaction point and then decaying a distance $d$ away, in some detector. My question is what is the smallest distance $d$ that can be measured ...

experimental setup to measure Center-Of-Momenta of products from spontaneous radiactive decay
This question is an attempt to complement this other question about fluctuations in radiactive decay.
This question is completely experimental though: in general, suppose i have certain sample of a ...
