During the 17th European Conference on Applied Superconductivity (EUCAS) 2025, Alexandre Arsenault won the ESAS Early Career Prize in the Large Scale category for his presentation entitled «Progress on a meter-long high temperature superconducting bulk staggered array undulator». These awards are given biennially to PhD students or individuals within 3 years of their PhD completion for outstanding work presented during the EUCAS conference.
Alexandre’s work is supported by CHART’s HTS bulk undulator program, which aims at achieving the highest possible undulator field with short period for use in the I-TOMCAT beamline at the Paul Scherrer Institute. With the use of a meter-long 10 T Nb3Sn solenoid and a staggered array of 200 GDBCO bulks, the project has the ambition to achieve an undulator field as high as 2T on-axis for a 10mm period length. Achieving this would enable the beamline scientists at the I-TOMCAT beamline to get two orders of magnitude higher X-ray photon flux at higher energies, making their experiments faster and with higher resolution.
