Facility for Antiproton and Ion Research

FAIR is• An international accelerator facility of the ”next generation”• Located at GSI, utilising the existing accelerator facilities

(UNILAC)• Consists of double synchrotron (SIS 100/300), production target

and storage rings FAIR accelerators will provide– Highest Beam

Intensities– Brilliant Beam Quality– Higher Beam Energies– Highest Beam Power– Paraller Operation

FAIR experiments

• Compressed Baryonic Matter experiment (CMB) • Electron-Ion Scartering in a Storage Ring (ELISe)• Facility for Low-energy Antiproton and heavy-Ion Research (FLAIR)• High Energy Density Matter Generated by Heavy Ion Beams (HEDqeHOB)• Stored Particles Atomic Physics Research Collaboration (SPARC)• Proton Antiproton Darmstad experiment (PAnDa)• The Super Fragment Recoil Separator project (S-FRS)• International Nuclear Structure and Astrophysics Community (NuStAR)• High Energy Irradiation Facility for Biophysics and Materials Research


Super-Fragment Recoil Separator

• Production of exotic nuclear species by fragmentation, spallation and fission of relativistic heavy ions up to 238U and 1500 MeV/u

• Selection of wanted species by magnetic fields (superconducting magnet coils) combined with ion tracking

• Three branches: High Energy, Low Energy, and the Ring Branch

NUSTAR – Nuclear STructure, Astrophysics and

Reactions• Collaboration of the international nuclear structure and astrophysics community• 440 scientists from more than 100 institutions • Current experimental programmes concentrate on the SIS18/FRS and

UNILAC/SHIP facilities at GSI, supported by corresponding theoretical studies. • The main goal is to develop, construct and operate the Super - FRS rare isotope

beam facility and its related ambitious experimental set-ups at future FAIR.• NuStAR projects at FAIR :

– ELISe - Electron-Ion Scartering in a Storage Ring – ILIMA - Isomeric Beams, Lifetimes and Masses– EXL - Exotic nuclei studied in light ion induced reactions– R3B – Reactions with Relativistic Radioactive Beams– HiSpec/DeSpec – High Resolution In-flight Spectroscopy/Decay Spectroscopy– MATS - Precision Measurements of very short-lived nuclei using an Advanced

Trapping System for highly-charged ions– LaSpec – Laser Spectroscopy– Super-FRS

Low energy branch experiments

FAIR is

• Fission product (A,Z) distribution provides information on fission process

• Wide range of independent cross sections needed for model/theory development

• Simulations of ISOL-RIB targets (e.g. EURISOL)• Simulations of ”Generation 4” nuclear reactors• Nuclear structure experiment planning

• HiSpec/DeSpec

• LaSpec

• MATS

•Energy buncher / high resolution separator

•Gas cell


LEB : HiSpec and DeSpec

HiSpec project

• Nuclear reactions with radioactive beams

– at intermediate energies from the S-FRS – at Coulomb barrier energies with further deceleration

– single step Coulomb excitations – fragmentation reactions – inelastic scattering– transfer reactions – fusion evaporation reactions

– transition probabilities– single particle spectroscopic factors– high spin states, etc.

• Complementary to work at R3B

– energy scale!

DeSpec concept

• Deep implantation of the ions in a highly pixellated active stopper -> correlation of ion to its subsequent beta decay.

• Neutron and high resolution gamma-ray detectors in a compact arrangement around the active stopper in a highly flexible and modular geometry will be at the heart of this set-up.

• Complementary measurements – Total Absorption Gamma technique – measurements of nuclear g-factors

and quadrupole moments – level half lives .

• high resolution Ge detectors • AGATA γ-ray tracking array• beam tracking and identification detectors before and behind the secondary target • charged particle detectors • neutron detector array• plunger • magnetic spectrometer

LaSpec

Laser Spectroscopy of Short-Lived Nuclei at FAIR’s Low Energy Branch • laser spectroscopy of the stopped, cooled, and bunched radioactive species with

fluorescence, resonance ionization and polarization based spectroscopic techniques.

• model-independent isotopic and isomeric nuclear spin, magnetic dipole moments, electric quadrupole moments and changes in mean square charge radii

• provides an unparalleled opportunity to study the most exotic, and short-lived, nuclear species to the limits of nuclear stability


MATS

Precision Measurements of very short-lived nuclei using an Advanced Trapping System for highly-charged ions

• high-precision mass measurements • in-trap conversion electron and alpha spectroscopy• electron beam ion trap (EBIT) for charge breeding • ion traps for beam preparation • high precision Penning trap system for mass measurements • Fourier-Transform-Ion-Cyclotron-Resonance (FT-ICR)

contribute towards running costs

FAIR pricetag: 1.2 GEuro

”I do not know why people are so impressed by money. I think that the first experiment that is done pays for the machine. After that, it’s gravy. I don’t think we should worry so much about money. Just because a machine costs a lot of money doesn’t mean you have to use it for a lot of dump experiments.”

- Isaac Rabi, 1943 Nobel Prize winner for studies on the magnetic moments of nuclei


IN-KIND SPECIFICATION Instruction

Each component of FAIR will be bought, built, or in any sense achieved according to a specification.

This principle is valid for all components including in-kind contributions.The rules of placing an order to a firm or to a contributor are discussed in the

AFI – but in any case organisationaland technical supervision of the component will be done according to given

specs.These specs will be a "tool kit" for the IKAB to give advices for in-kind

contributions.By defining Specs we define the contributors as being "Contractors", FAIR

GmbH as "customer" and the relationbetween them as a "purchase-like" situation.The contributor, which may have any organisational form agrees to take over

certain duties from FAIR withaccepting a contribution.Among these duties there is the duty to supervise the fabrication of the

component and to report to FAIR.It may be possible, that he needs technical expertise, in which case he will be

helped by experts of GSI or otherexternal experts sent by FAIR GmbH.In any case the contributor has to establish a connection from FAIR GmbHto the productions site of the component.
