Neutrino detection by inverse beta decay

Click For Summary
SUMMARY

Neutrinos can be detected through inverse beta decay, with a probability of interaction between a neutrino and a proton estimated at 10-43. To ensure that one out of one million neutrinos interacts with a proton, the dimensions of a water-filled detector must be calculated based on the number of protons in water. The mass density of water and the number of protons per gram are critical factors in determining the total mass and volume of the detector required for effective neutrino detection.

PREREQUISITES
  • Understanding of inverse beta decay
  • Knowledge of the mass density of water
  • Familiarity with the concept of interaction probability
  • Basic principles of particle physics
NEXT STEPS
  • Calculate the total number of protons in a given volume of water
  • Research the interaction length of neutrinos in various mediums
  • Explore the design and scaling of neutrino detectors
  • Study the principles of particle detection and measurement techniques
USEFUL FOR

Physicists, researchers in particle physics, and engineers involved in the design of neutrino detection systems will benefit from this discussion.

Hi,

I have the following question: Neutrinos can be detected by an inverse beta-decay. The probability for an interaction of a neutrino and a proton is 10^(-43). How large should be a detector filled with water in order to let interact one of 1 million neutrinos with a proton? What would be the mass of the filling of the detector?

I am not sure how to proceed. I know the number of protons in a water molecule but how can I get the dimensions of the detector from it? As for the mass filling?
Shouldn't there be additional information as for example the interaction length of neutrinos, I mean how far they fly before interacting/annealing etc.?

I would be grateful for every hint in the right direction.
Thanks
Emil

What is the mass density of water? How many protons are there per gram of water? Can you use these two numbers to find out the total number of protons in a volume of water?
