TI - Measurements of Small Vertical Beamsize using a Coded Aperture at Diamond Light Source
J2 - Proc. of IBIC2014
AB - Diamond Light Source produces a low emittance 3GeV electron beam which is now regularly operated at 8pm.rad vertical emittance. This corresponds to a vertical beamsize of just 13um in the dipole, which is at a high vertical beta location and routinely used for observing the synchrotron radiation using a pinhole camera. Deconvolution of the images from the pinhole camera to maximise resolution is limited by uncertainly regarding the precise shape of the pinhole, resulting in uncertainty on its computed point spread function. Recently a coded aperture has been installed which offers the potential to improve upon the traditional pinhole measurement by offering both higher resolution and increased flux seen through a larger total aperture, however, at the cost of significantly more complex analysis of the recorded images. A comparison of results obtained using the coded aperture and those achieved using the conventional pinhole is presented.
