| Abstract |
This work deals with the FEA study, design and optimization of the LOREA dipole vacuum chamber and Glidcop Al-15 crotch absorbers. At present LOREA is the ninth beam-line being designed at ALBA with an Insertion Device (ID) consisting of an Apple II-type helical undulator. For the standard dipole chamber the vertical polarized light hits the walls because of the very narrow vertical aperture between the cooling channels. In vertical mode the ID vertical divergence equals ± 2.2 mrad and the peak power density and total power are 5.6 kW/mrad² and 5.5 kW, respectively. Due to the high power a temperature as high as more than 600 °C is calculated. In consequence the dipole chamber has to be modified and the absorbers have to withstand the Bending Magnet (BM) and ID radiation. The new absorbers have to be thicker and its cooling channels are farer from BM power deposition than the standard absorbers. The thermal mechanical simulations show good results, the new absorbers are in a safe range, the maximum temperature, stress and strain are 309.2 °C, 164.2 MPa and 0.14%, respectively. The main ALBA Storage Ring design parameters used in the simulations are: 3 GeV, 400 mA and 1.42 T (BM).
