چکیده

At ANKA, the Karlsruhe synchrotron radiation source, the so called short bunch-length operation mode allows the reduction of the bunch length down to a few picoseconds. The micro-bunching instability resulting from the high degree of longitudinal compression leads to fluctuations in the emitted intensity in the THz regime, referred to as bursting. For extremely compressed bunches at ANKA bursting also occurs, in a certain current range, below the main bursting threshold. This contribution shows measurements of this short bunch-length bursting and makes first comparisons with theory.

Spectral Analysis of Micro-Bunching Instabilities using Fast THz Detectors

Micro-bunching instabilities occur at synchrotron light sources when the particle density rises due to compression of the electron bunches. They lead to powerful bursts of coherent synchrotron radiation (CSR) in the THz range at the cost of very unstable intensity and spectral properties, highly fluctuating on a millisecond time scale. For interferometry this changing source demands a long aver...

Bunch Length and Impedance Measurements at Spear3

Streak camera measurements were made at SPEAR3 to characterize longitudinal coupling impedance. For the nominal optics, data was taken at three rf voltages and a single-bunch current range of 0-20mA. Both bunchcentroid phase shift and bunch lengthening were recorded to extract values for resistive and reactive impedance. An (R+L) and a Q=1 model were then back-substituted into the Haissinski eq...

Status of Bunch Deformation and Lengthening Studies at the Anka Storage Ring

At the ANKA storage ring (Karlsruhe, Germany) we use a Hamamatsu synchroscan streak camera to study the current dependent bunch lengthening and deformation effects. Previously the camera was used at an IR port, being available only occasionally. In October 2010, a dedicated beam line for the streak camera became operational. It is designed to have minimum dispersion and sufficient flux in the o...

THz BURSTING THRESHOLDS MEASURED AT THE METROLOGY LIGHT SOURCE

At the Metrology Light Source (MLS) [1] owned by the Physikalisch-Technische Bundesanstalt (PTB) the bunch length can be varied by more than two orders of magnitude [2]. The bunch length manipulation is achieved by varying different machine parameters, such as RF-voltage amplitude up to 500 kV and the momentum compaction factor α over three orders of magnitude. The subject of this article is th...

CHARACTERIZING THz COHERENT SYNCHROTRON RADIATION AT THE ANKA STORAGE RING∗†

In a synchrotron radiation source coherent infrared (IR) radiation is emitted when the bunch length is comparable to the wavelength of the emitted radiation. To generate coherent THz (far IR) radiation, the ANKA storage ring is operated regularly in a dedicated low-alpha optics. Different bunch lengths, corresponding to different spectral ranges of the THz spectrum and various electron beam ene...
