Theoretical instability thresholds are estimated by numerically solving the Vlasov-Fokker-Planck equation and/or by multi particle tracking and taking into account the shielded CSR-interaction. Some of the issues with the calculations, the determination of the theoretical thresholds as well as the derivation of a general scaling law will be presented PB - JACoW CP - Geneva, Switzerland SP - 1651 EP - 1654 KW - synchrotron KW - shielding KW - damping KW - radiation KW - electron DA - 2016/06 PY - 2016 SN - 978-3-95450-147-2 DO - 10.18429/JACoW-IPAC2016-TUPOR003 UR - http://jacow.org/ipac2016/papers/tupor003.pdf ER -
