PILGRIM, a Multi-Reflection Time-of-Flight Mass Spectrometer for Spiral2-S3 at GANIL

Abstract : PILGRIM is a Multi-Reflection Time-of-Flight Mass Spectrometer currently under development at GANIL for the S3 (Super Separator Spectrometer) collaboration and dedicated to the study of the ground-state properties of exotic nuclei. MR-ToF devices have proven to be effective tools for isobar separation (with mass resolving powers in excess of 105105) and high-precision mass measurements (relative mass uncertainty down to a few 10-710-7) within a few tens of milliseconds. These features make them extremely interesting for ensuring beam purity and accurate mass determinations of very exotic, short lived nuclei. PILGRIM is to be set up in the future low energy branch of the S3-Spiral2 project and may also be used as a beam purifier in front of the double Penning trap PIPERADE at DESIR-Spiral2. An electrostatic 90 degree quadrupole deflector to be placed between an RFQ cooler-buncher (for beam preparation) and PILGRIM is also under study. The study on the deflector focuses on conserving the beam features, especially the time-of-flight spread of the ion bunches which has a direct impact on the resolving power of a multi-reflection device.
