TY - CONF AU - Vagin, Pavel AU - Neumann, Paul AU - Tischer, Markus TI - Magnetic Measurement Developments for Undulators CY - Geneva PB - JACoW, Geneva, Switzerland M1 - PUBDB-2015-00047 SN - 978-3-95450-132-8 SP - 2016-2018 PY - 2014 AB - FLASH2 is an extension of the present VUV-FEL facility at DESY. It includes a separate tunnel with a 12 x 2.5m = 30m long planar hybrid undulator. The undulators have 31.4mm period length and 1T field at a minimum gap of 9mm. The paper presents recent progress in the magnetic measurements of these undulators. Several specific details of the measurement tools will be discussed like peculiarities in the Hall probe calibration and noise, positioning accuracy and synchronization of voltage measurement with probes movement during scan, noise issues of various voltage integrators for stretched wire and search coil measurements.
