Monoenergetic positron beams of high intensity are of major interest in atomic and particle physics as well as in material science. The intensity of conventional positron beams using β + sources amounts typically to 10 6 positrons per second. Therefore, great efforts are undertaken to generate positrons by pair production using bright γ-sources, i.e. bremsstrahlung in a target at linear accelerators, γ-radiation from the nuclear fission or high-energy prompt γ-rays after thermal neutron capture. The NE utron induced PO sitron source at MU ni C h, NEPOMUC, is installed at the new research reactor FRM II. The world's highest positron intensity of up to 10 10 positrons per second is expected at this novel user dedicated positron beam facility. Since the final license for reactor operation was granted in May 2003 positrons will presently be available at FRM II. In this work, a brief overview of positron beams is given and the status of the positron project NEPOMUC as well as the linked experiments is reported. |
