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, so super-Gaussian distribution were fitted to data. Quadrupole scanning method shows that: [math] \epsilon_{n,x} \lt math\gt is[/math]11.4 \pm 0.6~\mu m</math> and [math]\epsilon_{n,y} \lt math\gt is[/math] 9.3 \pm 1.8~\mu m.
