Abstract
A high brightness electron Linac is being built in the Compton Gamma Source at the ELI Nuclear Physics facility in Romania. To achieve the design luminosity, a train of 32 bunches with a nominal charge of 250 pC and 16 ns spacing , will collide with the laser beam in the interaction point. Electron beam spot size is measured with an OTR (optical transition radiation) profile moni-tors. In order to measure the beam properties, the optical radiation detecting system must have the necessary accu-racy and resolution. This paper deals with the studies of different optic configurations to achieve the magnifica-tion, resolution and accuracy desired considering design and technological constraints; we will compare several configurations of the optical detection line to justify the one chosen for the implementation in the LinacFile | Dimensione | Formato | |
