Description
Cooling of secondary beams is often critical to accelerator based nuclear and sub-nuclear physics, with beams ranging from positrons e+ to muons μ+/- to hadrons (for the respective collider facilities) to exotic nuclei ions (like 132Sn1+) as in the SPES (Selective Production of Exotic Species) project at LNL. A prototype of a radiofrequency quadrupole (RFQ) cooler (RFQC) was developed at LNL and is under test in the Eltrap facility at Milan University; Eltrap provides a solenoidal magnetic field. Typical limits of RFQC and high resolution mass spectrometer (HRMS) performances are discussed, and relevant formulas are implemented in easy reference tools; HRMS requires less than 1 eV energy spread. The necessary collisional data are reviewed, in particular for Cs+ against He gas, whose pressure ranges from 2 to 9 Pa; status of Milan test bench is updated, with radiofrequency multiplexer and matching box details; the energy analyzer concepts are discussed. Practical consideration on gas pumping are also included.
