Emittance measurements using synchrotron radiation are usually performed using x-rays to avoid diffraction limits. Interferometric techniques using visible light are also used to measure either the horizontal or the vertical beam projection. Several measurements rotating the interferometry axis are needed to obtain a full beam reconstruction.
We present a new interferometric aperture...
As BESSY II uses complex filling patterns for standard operation as well as other modes of operation, it is necessary to have bunch-resolved diagnostic tools. While a streak camera has been successfully used for the longitudinal electron-beam diagnostics a fast-gated ICCD camera is being implemented on the neighbouring beamline to provide bunch-resolved diagnostics in the transverse...
In the scope of SOLEIL II, the booster must also be upgraded to reduce from 130 to 5 nm.rad the emittance of the beam delivered to the ring.
Control of the emittance in the booster will become crucial to ensure the nominal performance of the storage ring injection.
The SOLEIL I booster is already equipped with a Visible Synchrotron Radiation Monitor (MRSV). This equipment, made of an...
A third branch at the booster optical beamline has recently installed for research and development studies. Topic should cover beam characterisation and the accelerator physics university seminar. A CMOS camera aided by programble lens and mirrors replicate the existing source point imaging diagnostics.
During the studies it has been found that the polarisation shows non-linear...
