-A 16 MeV S-band linac at the Idaho Accelerator Center was recently reconfigured to produce a secondary beam of positrons by sending a 100 mA peak electron currents onto a Tungsten converter. The transverse electron beam emittance was measured to determine the optimal configuration using a quad triplet system  to capture the positrons escaping the downstream side of the Tungsten converter.  In 2011, we developed a beam imaging system with a digital CCD camera, three optical lens, and an OTR screen for the emittance measurement. In this paper, we describe the hardware and performance of our beam imaging system.

The transverse electron beam emittance was measured to optimize a quad triplet system positrons collection system escaping on the downstream side of the Tungsten converter.  In 2011, we developed an optical transmission radiation (OTR) based beam imaging system coupled to a digital CCD camera using three optical lens to measure the emittance. In this paper, we describe the OTR beam imaging system and its performance.

-At the Idaho Accelerator Center (IAC), there is a 16 MeV S-band High Repetition Rate Linac (HRRL), which was recently reconfigured its beamline to develop a positron source. The positron source can be generated by sending high quality electron beam to a Tungsten converter. To match optics of the newly configured beamline and to estimate quality of electron beam, we have to measure the transverse emittance of electron beam. In 2011, we developed a beam imaging system with a digital CCD camera, three optical lens, and an OTR screen for the emittance measurement. In this paper, we describe detailed hardware of our beam imaging system and its experimental results.

-We performed transverse emittance measurement of medical linac at physics department of Idaho State University. Al foil with a thickness of 1 micron used to observe electron via OTR. Imaging system composed of 3 lenses of different focal length were used to improve image quality. We found the projection of electron beam does not follow Gaussian distribution. So, we fit Super-Gaussian distribution to the beam and extracted the transverse emittance.

-We used 3 lenses to collect OTR light from Al target. They have focal length of 100 mm, 500 mm and 50 mm, they were called collector lens, fine tune lens and main focus lens respectively. Collector lens has the middle focal length, collects most of the light from the source. Fine tune lens has the biggest focal length, act as fine tune of magnification. Main focus lens: has the smallest focal length, has biggest focusing strength, so act as main focus of light and focuses light to CCD.
