Beam-line configuration

OEDO project is an upgrade of the beamline which is currently operated as "High-Resolution Beam-line" in RIBF. In March, 2017, new devices of a STQ (Superconduting Triplet Quadrupole magnet) and an RF-deflector were installed. The almost part of OEDO beamline was completed by rearrangement of existing beamline devices. The commissioning of the OEDO beamline was performed in June, 2017.

The OEDO beamline shares the elements with BigRIPS from F0 to F6. The elements of OEDO after F6 are listed below and the OEDO beamline finally gets connected to the SHARAQ spectrometer.

Acceptance and transmission

Based on the preliminary report of the commissioning results, we provide the transmission of the OEDO beamline. As conditions of the secondary beam, the momentum was set to be ± 1%, the spot size at BigRIPS F3 was 10 mm in diameter. The transmission of the secondary beam to the secondary target position (S0) was preliminarily estimated to be 10%.
