We are going to search for the material that best emits low energy muonium into vacuum by tracking of positrons from muon decay in vacuum. Based on successful increase of the emission rate in the previous measurement with laser ablated silica aerogel, we will maximize the muonium yield by systematic comparison of the simulation and the measurement for various surface structures.
