Offline test of a Cryogenic Stopping Cell for the Low-Energy Branch of the Super-FRS at FAIR
Here we report the first successful offline test of the cryogenic gas stoping cell developed for the low-energy branch of the Super Fragment Separator (Super-FRS) at FAIR in Darmstadt, Germany. This gas cell has a stopping volume of length 1 m and diameter 0.25 m. A DC field throughout the length of the cell and a RF carpet with DC field superimposed at the exit side to guide the ions towards t...
متن کاملLarge Aperture Hexapole Magnets for the Super-FRS LEB Spectrometer
It is proposed to use a magnetic spectrometer [1,2], located behind the Super-FRS [3] in the LEB cave, for experiments with exotic beams at low and intermediate energies (5 to 200 MeV/A) and stopped beams. For the HISPEC/DESPEC [4] experiments where exotic ions are measured in coincidence with gamma spectroscopy at the secondary target MF10, a good mass identification is necessary. This require...
متن کاملA Multiple-Reflection Time-of-Flight System for Mass Measurements and Isobaric Separation for SHIPTRAP and the LEB of the Super-FRS at FAIR
At low-energy radioactive ion beam facilities such as SHIPTRAP and the Low-Energy Branch of the Super-FRS at FAIR, mass measurements and spectroscopy for a broad range of nuclei can be performed. Access to these nuclei is limited by their lifetime and the amount of isobaric contamination. To help to overcome these limitations, a multiplereflection time-of-flight mass spectrometer (MR-TOF-MS) sy...
متن کاملCalculation of activation and dose spatial distributions induced by high intensity uranium beams at the Super-FRS fragment separator at FAIR
A calculation of activation and induced dose spatial distribution caused by 1.5 GeV/u U irradiation was carried out for the design of the shielding of the Super-FRS[1], which is under development for the future project at FAIR GSI. The calculation is based on a model newly developed in this study and it is divided into; (1) Residual nuclei calculation (2) activation calculation, (3) dose conver...
متن کامل3D hydrodynamic calculations of the Super-FRS liquid lithium target
A careful choice of the production target is very important for SUPER-FRS experiments at FAIR. A windowless liquid Lithium jet is one of the target configurations that are discussed [1]. Focusing of the primary beam improves the resolution of the isotopes and the transmission of the secondary beam, but can destroy the target. Analysis of the target behavior after the beam irradiation provides t...
