MOAM1HA01 | Beam Cooling, Past, Present and Future | 1 |
|
||
The cooling methods in particle accelerator technologies has already longstanding history that has been began by Gersh Budker in 1966 and is under intense and active development since that time and up to now. Further still, more and more novel ideas of both principle and technological character appear continually. In this review paper the history of cooling methods creation, present status of the methods, future projects with cooling methods application, trends in their development and some novel ideas are briefly presented. | ||

WEPPO02 | Stacking Modes with Barrier Buckets Method in NICA Collider | 97 |
|
||
A new accelerator complex NICA is under construction at JINR now. The main goal of this project is to reach a very high luminosity of 1027 [cm-2 c-1] in the colliding experiments with gold ions in the energy range of 1 – 4.5 GeV/u. Both electron and stochastic cooling methods will be used to provide the necessary beam parameters. The beam stacking in the longitudinal phase space with stationary and moving barrier buckets in NICA Collider under action of cooling methods or without cooling are presented in this report. | ||
WEPPO08 | Electron Cooler for the NICA Collider | 113 |
|
||
The goal of the cooling system of the NICA collider is to meet the required parameters of ion beams in energy range of 1–4.5GeV/u that corresponds to the 0.5–2.5 of the electron MeV. The electron cooler is developed according to the available world practice of manufacturing of similar systems. The main peculiarity of the electron cooler for the NICA collider is use of two cooling electron beams (one electron beam per each ring of the collider) that never has been done. The acceleration and deceleration of the electron beams is produced by common high-voltage generator. The cooler consist of three tanks. Two of them contain acceleration/deceleration tubes and are immersed in superconducting solenoids. The third one contains HV generator. The scheme of the electron cooler, its main parameters and operation regime are presented. | ||

WEPPO11 | LEPTA Project: Towards Positronium | 119 |
|
||
The Low Energy Positron Toroidal Accumulator (LEPTA) at JINR is close to be commissioned with circulating positron beam. The LEPTA facility is a small positron storage ring equipped with the electron cooling system and positron injector. The maximum positron energy is of 10 keV. The main goal of the project is generation of intensive flux of Positronium (Ps) atoms - the bound state of electron and positron, and setting up experiments on Ps in-flight. The report presents an advance in the project: up-grade of LEPTA ring magnetic system, status of the construction of positron transfer channel, and the electron cooling system, first results of low energy positron beam formation with 22Na radioactive positron source of radioactivity of 25 mCi. | ||
THAM2HA01 | Beam Accumulation and Bunching with Cooling | 170 |
|
||
The accumulation of anti-proton beam in the storage ring was performed at CERN and FNAL with use of a stochastic stacking system. In the original version of the FAIR such a concept was envisaged at the accumulator ring named RESR. However in the modularized start version of FAIR, the RESR was postponed and the new concept of anti-proton accumulation in the High Energy Storage Ring (HESR) was strongly demanded. The barrier bucket system with stochastic cooling was found with simulation work to have enough capabilities to accumulate the pre-cooled 3 GeV anti-proton beam in the HESR. The Proof Of Principle (POP) experiment was performed at the GSI storage ring ESR with the use of Ar and Xe ion beam employing both stochastic and electron cooling. The experimental results were well in agreement with the prediction of the simulation study. The concept of BB accumulation could be applied to the planned Collider of the NICA project at JINR. In the present paper the concept of BB accumulation and the short bunch formation including the space charge effects are presented as well as the analysis of POP experiment. | ||

THPM2HA01 | Present Status of NICA Project | 197 |
|
||
Nuclotron-based Ion Collider fAcility (NICA) is the new accelerator complex being constructed in Joint Institute for Nuclear Research. General goal of the project is to start experimental study of hot and dense strongly interacting QCD matter and search for possible manifestation of signs of the mixed phase and critical endpoint in heavy ion collisions. In this report the present status of the NICA accelerator complex are presented. | ||
