THPLT109 | The Upgraded Optical Diagnostic of the VEPP-4M Collider | 2736 |
|
||
The upgraded optical diagnostic of the VEPP-4M collider is described. The system abilities are improved sufficiently in comparing with the previous version. Now the diagnostic supplies the data about an electron/positron beam transversal and longitudinal size, shape and position. It is applied to study the electron beam "tails" and turn-to-turn beam profile dynamics. The system is used to tune of the beam pass-by from the VEPP-3 booster to the VEPP-4M collider and provides the permanent measurements of the synchrotron and betatron frequencies. |
