The Optical Dissector Bunch Length Measurements at the Metrology Light Source JACoW Geneva, Switzerland 978-3-95450-192-2 10.18429/JACoW-IBIC2017-TU1AB3 English 125-128 TU1AB3 ion electron optics synchrotron diagnostics Contribution to a conference proceedings 2018 2018-03 https://doi.org/10.18429/JACoW-IBIC2017-TU1AB3 http://jacow.org/ibic2017/papers/tu1ab3.pdf The bunch longitudinal profile measurements using an optical dissector are introduced in the paper. The principles of the dissector operation are briefly discussed. The first measurements using the optical dissector at the Metrology Light Source are presented. Results are analyzed and compared with the bunch profiles from the streak camera measurements. Measurement errors and limitations of the both methods are estimated. Possible applications for the presented technique are discussed.
