Abstract
Detecting relic neutrinos is a longstanding goal in fundamental physics. Experimentally, this goal is extremely challenging as the required energy resolution is defined by the tiny neutrino masses ($\sim\SI{10}{\milli\electronvolt}$). The current consensus is that sufficient statistics together with the clean spectrum could only be achieved if beta decayers are attached to a solid state substrate. However, this inevitably imposes irreducible intrinsic limitations on the energy resolution coming from the Heisenberg's uncertainty principle. This limitation appears to be critical for the currently accepted decayer - Tritium. Here we analyze ways of mitigation of this limitation that are known at the moment and provide an up-to-date conclusion regarding the viability of using the Tritium for the relic neutrino detection.
