| Apr 16, 2019 at 15:17 | comment | added | rob♦ | @CinaedSimson Scintillators make light; free charges in a scintillator aren't converted into a detectable current. You're thinking of something like a silicon-strip or other semiconductor detector. | |
| Apr 13, 2019 at 23:35 | comment | added | Cinaed Simson | I would guess the electron would join the electron parade to the PM? But that still leaves protons lying around. So I have another related question, does the detector float electrically relative to ground during data collection, and reconnected to ground after the data run to allow electrons to flow back into the detector? | |
| Apr 12, 2019 at 22:44 | comment | added | Betsy | @CinaedSimson yes there is a photomultiplier at the end of the scintillator. But what would the electron combine with? The recoil proton assists in producing a photoelectron when it interacts with a scintillation molecule | |
| Apr 12, 2019 at 22:35 | comment | added | Cinaed Simson | Is there photo multiplier tube on the end of scintillator? How do they detect an event electronically? | |
| Apr 12, 2019 at 21:51 | comment | added | Jon Custer | @CinaedSimson - indeed, with time, some electron will combine most likely. The chance it is the original electron is pretty small, but that will depend on the recoil energy. | |
| Apr 12, 2019 at 21:34 | comment | added | Cinaed Simson | Actually, if you have a hydrogen atom, and it collides with a neutron to produce a proton and an electron, doesn't the proton and the electron recombine to produce hydrogen again? | |
| Apr 12, 2019 at 19:25 | comment | added | Michael Seifert | Naively, I would think that it would be captured by another molecule in the scintillator, making that molecule an ion. But scintillator physics is well outside of my expertise. | |
