FRCAMH05 | Booster Synchrotron at NICA Accelerator Complex | 160 |
|
||
NICA is the new complex being constructed on the JINR aimed to provide collider experiments with ions up to aurum at energy of 4.5x4.5 GeV/u. The NICA layout includes 600 MeV/u Booster synchrotron as a part of the injection chain of the NICA Collider. The main goals of the Booster are the following: accumulation of 4E109 Au31+ ions; acceleration of the heavy ions up to energy required for effective stripping; forming of the required beam emittance with electron cooling system. The layout makes it possible to place the Booster having 210.96 m circumference and four fold symmetry lattice inside the yoke of the former Synchrophasotron. The features of the Booster, its main systems, their parameters and current status are presented in this paper. | ||

THPSC052 | The Longitudinal Broadband Impedance and Energy Spread Measurements at VEPP-4M | 650 |
|
||
The paper presents studies of the longitudinal broadband impedance of VEPP-4M and measurements of its bunch energy spread at different energies in range of 1.45 - 3.5 GeV. In order to measure the longitudinal bunch size at different currents we used PS-1/S1 streak camera with picosecond temporal resolution. Considering that influence of collective effects is negligible at low currents we determined bunch energy spread from its length at low currents. Collected bunch length data demonstrate microwave instability thresholds and potential well distortion lengthening. Potential well distortion was studied at 3 GeV and 3.5 GeV. Measured potential well distortion lengthening was used to estimate a value of the reactive part of the longitudinal impedance. Observed microwave instability thresholds was used to measure the value of broadband impedance. Measured value of the VEPP-4M is 7.9 ± 1.5 Ohm. | ||
