A method is described for measuring, with counters and fast electronics, the momentum of particles in a high energy beam which has a large spatial and angular spread. The beam is sent through a deflecting magnet and hodoscopes are used at three points along the trajectory. The momentum is inversely proportional to a function that is linear in the positions of the particle in the three hodoscopes and independent of incident particle angle. The main feature of our method is that this linear function can be produced by appropriate summing of the counter discriminator signals. The pulse height of the resulting signal can be used to isolate particles in any given momentum region; the signal rate, up to 100 Mcps, implies it can be used in subsequent fast logic. We discuss the application of this technique to a muon beam of 11 GeV/ c nominal momentum which was 15 cm in size and with 20 mrad angular divergence. |
