Hard X-ray operation mode at VEPP-4M
There is synchrotron radiation experimental program at electron-positron collider VEPP-4M. Taking to account maximum beam energy, hard X-ray experiments at the storage ring seems rather attractive. The paper describes VEPP-4M VEPP-4M performance at high energy with high current. New hybrid magnet wiggler developed recently specially to increase photon flux in the range of 50÷100 keV is also discused.
