[en] The ''standard'' luminosity of 2 x 10³² is taken as a goal for a device that measures charged particle momenta over a wide solid angle. It appears that a projection chamber is capable of operation in this mode providing care is taken to optimize the geometry with this high flux in mind. Some calculations have indicated that optimism is required but in no direction have the demands on the apparatus appeared to be well beyond those attainable. In addition dE/dx measurements yielding particle identification over the median momentum range, about 2 to 30 GeV/c, are also feasible
