WEPB04 | The VEPP-4M Dynamic Aperture Determination Through the Precise Measurement of the Beam Lifetime | 238 |
|
||
To determine experimentally the particle stable area in the electron-positron collider VEPP-4M we measure the beam life time with high accuracy as a function of moving aperture. The measurement is performed by a photodiode installed in the collider diagnostic beam line. The experimental set up and the measurement results are described. Comparison with the tracking simulation is presented. |
