The Novosibirsk ERL is used as a source of electron beams for the powerful Free Electron Laser. It is based on the normal conducting RF structure which operates in CW mode. The third stage of this facility which is the first in the world four-turn ERL has been commissioned recently. More than 90% of electrons were transported to the beam dump, which allowed to increase the average beam current up to 5 mA. The obtained parameters are sufficient to get lasing at the third stage FEL which will be installed at fourth track in the nearest future. In this paper we report the commissioning status and talk about further development of the Novosibirsk ERL and FEL facility.

Modeling and Optimization of Orbit Correction Using Fuzzy Logic

BINP SB RAS, Novosibirsk, Russia

This article describes a fuzzy logic model for beam orbit correction. Step 1. I have created a 'fuzzy logic engine', which works with a soft EPICS database. The EPICS database emulates PVs (Proccess Variable) of the magnetic system and PVs of the diagnostic systems: Beam Position Monitor, integrated beam currents, and radiation doses in the accelerator hall. Step 2. Currently, I am debugging the mechanism of feedback between the 'fuzzy logic engine' and fluctuations of diagnostics PVs. Next step. Adjustment of the time of feedback response of the 'fuzzy logic engine' to information coming from the control systems and FEL diagnostic systems in a hard real time mode.

The system of radiation diagnostics controls levels of radiation in the accelerator hall and in the adjacent rooms where works FEL personnel. The system provides radiation safety of personnel. The software performs data visualization and records the measured data into the database. The special ionization chambers installed in the accelerator hall. They keep track of the beam losses in the vacuum chamber, this information is used for correction of beam orbit. These sensors detect the induced radioactivity. Based on these data, we watch the degradation of the material of construction under the action of radiation.
