The 60 atm HP gas cell (HPG/60) is used for studies of muonium chemistry in the gas phase. It features a 0.1 mm muon entrance window made by boring almost all the way through the titanium end plate. This is the maximum thickness compatible with a surface muon beam. To eliminate all unnecessary materials in the muon beam, an in-vacuum muon counter is used which features a thin `button' of bare scintillator placed right over the entrance window and an aluminized mylar mirror to direct scintillation light to a photomultiplier tube.
