  VEPP-5 Injection Complex (IC) is designed to supply BINP RAS colliders with high energy electron and positron beams. Recently constructed K-500 beam transfer line connects IC to both VEPP-4M and VEPP-2000 colliders. IC two collider operation was successfully started in 2016. Nowadays, research on improvement of IC performance is carried out, in particular 10.94 MHz RF cavity was installed instead of 700 MHz one and a new 10 A electron gun installation is expected to be in winter 2018-2019. Moreover, streak-camera based longitudinal beam profile measurements in IC damping ring were carried out and BPM system in the damping ring was upgraded. Operation experience of IC and results of longitudinal beam profile measurements are reported.

  A distributed optical fiber based beam loss monitor has been implemented for the Budker INP Injection Complex designed to accelerate and store electron and positron beams up to 500 MeV. The principle of the device operation consists in detecting the Cherenkov radiation generated in an optical fiber by relativistic charged particles produced in an electromagnetic shower when beam hits the accelerator vacuum chamber wall. Single optical fiber section can cover the entire accelerator instead of using a large number of local beam loss monitors. Timing of optical signal gives the location of the beam losses along the beamline. In this paper summary of the monitor application at the BINP Injection Complex is given. Methods to improve monitor spatial resolution are discussed.
