Gas recirculation and purification system needed since gas pressure will be changed at higher SHMS momenta. Maintain sub-atmosphere (0.95 atm) pressure below 7.3 GeV/c. Maintain sub-atmosphere (0.95 atm) pressure below 7.3 GeV/c. Above 7.3 GeV/c, reduce gas pressure to maintain good π/K separation. Above 7.3 GeV/c, reduce gas pressure to maintain good π/K separation. Gap between the `set’ and `K’ curves takes into account the SHMS momentum bite and a possible 0.1 atm error in the setting of the gas pressure regulator.
