Intergrating CT - Bergoz Instrumentation - #1

Text version of the page

ICT integrates bunch charge without loss For transfer lines, injection/extraction monitoring For laser-plasma, wakefield accelerators Single very short bunches, down to femtoseconds are integrated without loss. Microsecond long trains of very short micro bunches are integrated with negligible loss. High sensitivity for pC resolution pulse measurement In-flange.ICT are mounted directly in the beam line. UHV compatible. Available for many pipe diameters: 1”, 1.5”, 2.5”, 4”, 6” and 8” Also with elliptical aperture or other arbitrary shape aperture. Ceramic gap, shields and wall current bypass are included. Bellows are not required. In-air ICT are installed over the vacuum chamber. It requires a “gap” in the vacuum chamber to prevent the wall current from flowing through the ICT aperture. The gap cab be a brazed ceramic ring or an organic material Oring depending on the vacuum requirements. Typical installations include bellows, a wall current bypass and an electromagnetic shield covering the ICT completely. Technology ICT combines two nested transformers: A shorted one-turn current transformer loads the bunch charge in a series of low-inductance capacitors distributed evenly around the transformer toroid. The full bunch charge is instantly loaded in those capacitors. A readout transformer transfers the charge loaded in the capacitor to its readout winding, at a slow pace determined by the RC time constant loading the winding. As a result of this very low frequency transfer, the eddy current loss in the cores are negligible. Alloys used to assemble these cores are specially annealed to lower their coercive field and further minimize core loss. V.1.0 ICT Integrating Current Transformer Integrates bunch down to femtoseconds
