Emittance Measurement of Varian Medical Linac

Abstract

Emittance of Varian High Rep-Rate Linac (HRRL) was measured with Optical Transition Radiation (OTR) at 14 MeV. Electron beam was observed at 10 [math]\mu m [/math] thick Al screen. Projection of beam appear to be sharper than Gaussian distribution, and super-Gaussian distribution were fitted. Quadrupole scanning method shows that horizontal and vertical are [math]11.4 \pm 0.6~\mu m[/math] and [math] 9.3 \pm 1.8~\mu m[/math] respectively.
