An X-ray Pinhole Camera System for Diamond
In this paper we present the X-ray pinhole camera designed for the measurement of the size, the emittance and energy spread of the electron beam at Diamond. The system has been kept as simple as possible. The pinhole and the imaging system are in air, and the X-ray beam from the bending magnet is filtered out through an Al window. The beam is imaged using a fluorescent screen and an IEEE 1394 c...
متن کاملImaging beyond the Pinhole Camera
The world’s first photograph was taken by Joseph Nicphore Niépce (1775–1833) in 1826 on his country estate near Chalon-sur-Sane, France. The photo shows parts of farm buildings and some sky. Exposure time was eight hours. Niépce used a pinhole camera, known as camera obscura, and utilized pewter plates as the support medium for the photographic process. The camera obscura, the basic projection ...
متن کاملA Pinhole Camera for Spear 2
A new pinhole camera system has been installed on Spear 2 to measure its vertical emittance. The hard X-rays from a bending magnet source point are imaged on a phosphor screen through a 30 um x 25 um pinhole aperture. The resolution of the system for 8 keV photons is limited to 31.2 um by Fraunhoffer diffraction and is much smaller than the 340 um FWHM vertical beam size corresponding to 0.9% v...
متن کاملMeasuring Beam Sizes and Ultra-Small Electron Emittances Using an X-ray Pinhole Camera.
A very simple pinhole camera set-up has been built to diagnose the electron beam emittance of the ESRF. The pinhole is placed in the air next to an Al window. An image is obtained with a CCD camera imaging a fluorescent screen. The emittance is deduced from the size of the image. The relationship between the measured beam size and the electron beam emittance depends upon the lattice functions a...
متن کاملNote: Diagnosing femtosecond laser-solid interactions with monochromatic Kα imager and x-ray pinhole camera.
An x-ray pinhole camera and a monochromatic K(α) imager are used to measure the interactions of intense femtosecond laser pulses with Cu foil targets. The two diagnostics give different features in the spot size and the laser energy scaling, which are resulted from different physical processes. Under our experimental conditions, the K(α) emission is mainly excited by the fast electrons transpor...
