Method for transporting charged particles from source to detector with an efficiency close to 100 percent

A method is examined for transporting charged particles over large distances (about 10 meters for electrons and positrons) with an efficiency close to 100 percent. The method is based on the drift of charged particles in the magnetic field of a linear conductor with a current directed parallel to the conductor. The method described can be developed into simple and reliable systems for detecting light charged particles. These systems would combine an extremely high luminosity with an effective shielding against background radiation from the source. Further advantages of the method are the simplicity of implementation and the absence of a large, heavy electromagnet.
