TI - A Compact In-Air X-Ray Detector for Vertical Beam Size Measurement at ALBA
J2 - Proc. of IBIC2014
AB - An in-air x-ray detector (IXD) was developed for ALBA to study the residual x-rays after traversing the 35mm copper crotch absorbers. The device prototype is placed in-air after such absorber, mounted flush with the vacuum pipe. The remaining x-rays (above 120 keV) generate a visible footprint if they impinge upon a sensitive enough scintillator. We are using a Cerium doped PreLude 420 (LuYSiO:Ce) screen, and the image is observed with a simple optics system mounted on a commercial CCD camera. This measurement allows evaluating the vertical electron beam size with exposure times in the order of seconds. Similar instruments are used at ESRF and ANKA storage rings. This paper presents the results of the first measurements with IXD and describes its potential to be used as a full diagnostics tool for the 3 GeV storage ring of ALBA.
