Magnetic sensitivity depends not only on material quality but also on the cavity geometry and on the residual magnetic field orientation. A presentation of experimental data will be done. These will be as well compared to the theoretical magnetic sensitivities calculated thanks to a simple Labview routine PB - JACoW Publishing CP - Geneva, Switzerland SP - 555 EP - 559 KW - cavity KW - niobium KW - experiment KW - SRF KW - accelerating-gradient DA - 2019/08 PY - 2019 SN - "" SN - 978-3-95450-211-0 DO - doi:10.18429/JACoW-SRF2019-TUP054 UR - http://jacow.org/srf2019/papers/tup054.pdf ER -
