Compact Variable-Gap Undulator with Hydraulic-Assist Driver: undulator harmonic energy scan test
Alexander Temnykh, Ivan Temnykh
In the compact variable-gap undulator with Hydraulic-Assist Driver, miniature hydraulic cylinders compensate for ~90% of magnetic forces and mechanical actuators are used to accura…
Compact Variable-Gap Undulator with Hydraulic-Assist Driver
Alexander Temnykh, Ivan Temnykh
Following successful proof-of-concept experiments, we constructed compact varying-gap undulator with Hydraulic-Assist Driver. The 1.5m long undulator features a pure permanent magn…
Hydraulic-Assist Driver for Compact Insertion Devices
Alexander Temnykh, Ivan Temnykh, Eric Banta
We have developed and tested a novel type of driver for insertion devices. In our approach, we compensate for the magnetic forces acting on the insertion device (ID) arrays by inst…
Accelerator Design for the CHESS-U Upgrade
J. Shanks, J. Barley, S. Barrett +10
During the summer and fall of 2018 the Cornell High Energy Synchrotron Source (CHESS) is undergoing an upgrade to increase high-energy flux for x-ray users. The upgrade requires re…
