4. Electron and stochastic beam cooling for intensive heavy ion beams at NICA complex: experiments and plans

Yegor TAMASHEVICH (Joint Institute for Nuclear Research)

Invited talk

The Nuclotron-based Ion Collider fAcility (NICA) is under mounting in JINR. The Collider first beam tests are planned for the second half of 2025. The goal of the NICA project is to provide colliding beams for studies of collisions of heavy fully stripped ions at energies up to 4.5 GeV/u. The NICA accelerator facility consists of following accelerators: the new acting heavy ion linac HILAC at...

70. Brief review of electron cooling at HIRFL-CSR and future plan at HIAF

HE ZHAO (IMP, CAS)

18/11/2024, 16:50

Since it was invented by Budker in 1967, electron cooling has been a powerful method to reduce the beam emittance and momentum spread, and has been successfully used in various applications, such as beam accumulation, increasing collision luminosity and some precision experiments. At IMP, we have operated two electron coolers, EC35 and EC300, in the HIRFL-CSR for nearly 20 years. Currently, a...

Talk

Recent storage ring experiments have demonstrated the power and the potential of laser cooling of bunched relativistic ion beams. Encouraged by this, the heavy-ion synchrotron SIS100 at FAIR (Darmstadt, Germany) will be equipped with a truly unique laser cooling facility. A sophisticated combination of 3 newly developed UV (257 nm) laser systems and modest rf-bunching will allow for fast...

31. Exotic structure studies of light neutron-rich nuclei via direct nuclear reactions

JIANLING LOU (Peking University)

18/11/2024, 17:30

In order to study the exotic structures of light unstable nuclei, we have developed a Large Acceptance Charged particle detector array at Peking University, LACPU, which is suitable for simultaneous measurement of various different direct nuclear reactions induced by radioactive beams on protons and deuterons in inverse kinematics [1,2]. The properties of LACPU, published experimental results...

22. Laser cooling of relativistic ion beams

Michael BUSSMANN (Helmholtz-Zentrum Dresden - Rossendorf)

Invited talk

We present an overview of laser cooling as a new method to cool highly relativistic beams at future research facilities such as FAIR and HIAF. We first dive into understanding the mechanisms of laser cooling at relativistic energies, giving estimates for cooling times and their scaling with beam energy and ion charge state for a given accelerator. We further look into the specific beam...

2. Schottky detection techniques for isotopic and isomeric mass and lifetime measurements in heavy ion storage rings

Shahab SANJARI (GSI Darmstadt)

19/11/2024, 11:10

Non-destructive Schottky detectors can be used to accurately determine masses and lifetimes of exotic nuclear species and their isomeric states in heavy ion storage rings. Single-ion sensitivity has been regularly achieved in the past using resonant cavity detectors. Recent designs and analysis methods aim to push the limits of measurement accuracy by increasing the dimensionality of the...

11. Towards electron cooling of heavy, highly charged ions in the HITRAP Cooling Trap

Simon RAUSCH (TU Darmstadt)

19/11/2024, 11:30

The HITRAP project at the GSI Helmholtzzentrum für Schwerionenforschung GmbH aims to provide cooled bunches of heavy, highly charged ions (HCI) for precision experiments. Produced at high energy, the HCI are subsequently decelerated by a linear decelerator down to 6 keV/u, at which point they are captured in the HITRAP Cooling Trap. In this Penning-Malmberg trap, the HCI can be cooled by a...
