One-dimensional beam ordering of protons in a storage ring.
نویسندگان
چکیده
The ordering of protons has been observed at a new storage ring, S-LSR, at Kyoto University. Abrupt jumps in the momentum spread and the Schottky noise power were observed for protons for the first time at a particle number of approximately 2000, upon applying electron cooling with electron currents of 25, 50, and 100 mA. The transition temperature was 0.17 and 1 meV in the longitudinal and transverse directions, respectively. The transverse temperature of the proton beam was much below that of electrons at the transition, which played an essential role in the ordering of protons.

The Iranian Light Source Facility (ILSF) as a national project is a 3 GeV third generation synchrotron light source facility which provides high energy super bright X-ray for the users. Design of the ILSF storage ring emphasizes an ultra low electron beam emittance (below than 5 nm.rad), beam current of 400 mA, great brightness, stability and reliability which make it competitive in the operati...
متن کاملPrecision Magnetic Elements for the Sns Storage Ring*
Magnetic elements for an accumulator storage ring for a 1 GeV Spallation Neutron Source (SNS) have been under design. The accumulation of very high intensity protons in a storage ring requires beam optical elements of very high purity to minimize higher order resonances in the presence of space charge. The parameters of the elements required by the accumulator lattice design have been reported....
متن کاملElectron Cooling Possibilities for Hera
Electron Cooling of the hadron beam in HERA could be a way to upgrade the luminosity for electron-proton and electron-heavy ion collisions. Because of the necessary electron energy of 450 MeV for cooling protons and about 180 MeV for cooling heavy ions the conventional approach using electrostatic DC sources is not possible. Instead an electron storage ring could be used. For this ring there ar...
متن کاملSpin motion at and near orbital resonance in storage rings with Siberian Snakes I : at orbital resonance ∗
Here, and in a sequel, we invoke the invariant spin field to provide an in–depth study of spin motion at and near low order orbital resonances in a simple model for the effects of vertical betatron motion in a storage ring with Siberian Snakes. This leads to a clear understanding, within the model, of the behaviour of the beam polarisation at and near so–called snake resonances in proton storag...

∗ Supported by HIRFL-CSR cooler storage rings project Abstract National key scientific project ‘HIRFL-CSR Cooler Storage Ring’ makes use of existing HIRFL as its pre-accelerator. In order to take the full capability of HIRFL, we have studied in detailed the matching modes between HIRFL and CSR. It is proposed to use two matching modes: direct matching between SFC (HIRFL injector cyclotron) and ...
