Design and Construction of SEM for Continues 200keV Electrostatic Accelerator | |

| Beam profile and position monitoring at continues beams aren't possible by electromagnetic based instruments such as Pick Up, by this regard, design and construction of SEM has done for 200 keV electrostatic machines which can be classified into mechanic and electronic sections. At mechanical section the vacuum chamber with 3 feed-through which each one has 32 pins was constructed then grids with 16 copper wire with length of 10 cm and 80 μm diameter at each vertical and horizontal direction considered. The produced signals amplified and then digitized by ADC and transferred by ATMEGA32 ports to PC which set by GUI (MATLAB) as data analyzer. Induced profile at quartz glass which is placed at the end of beam tube was considered as bench mark source. The electrical results were compared with the result of quartz as practical method and CST as simulation. high accuracy and precision deduced which is presented at this article. | ||
