Description

The LEMING (LEptons in Muonium INteracting with Gravity) experiment aims to measure the gravitational acceleration of Muonium (M = e$^−$ + μ$^+$ ) in the gravitational field of the earth. An essential part of this experiment is the reliable detection of M’s decay products, i.e. e$^+$ and e$^−$, at temperatures below 1$\,$K. The electron, referred to as atomic electron, can be accelerated to energies of $\mathcal{O}$(keV), thus requiring a sensitive detector. This work considers perovskite nanocrystals for the detection of the atomic electron. Preliminary tests at room and cryogenic temperatures are presented.
