	Funding: This work is supported by St.-Petersburg State University grant #9.38.673.2013. Methods of beam dynamics optimization of the first order are known and used for beam dynamics optimization. These method are based on numerical calculation of gradient of functional estimating beam quality. In this report, method of optimization is proposed that includes numerical calculation of the second derivations (Hessian) of the quality functional. Proposed method is applied for a beam in RFQ channel. Control problem is formulated. The propblem consists in minimizing of functional depending on the beam density and on control functions. The control functions are the acceleration efficiency, the synchronous phase, and the channel apperture. For numerical solution the control functions are taken in parameterized form. The process of optimization represents a sequence of steps with use of the first and the second derivatives on parameters, during which the value of the functional decreases. D.A. Ovsyannikov, O.I.

Three electrode gun, consisting of spherical cathode, control electrode and anode, has been designed. Anode potential was varying between 30 kV and 50 kV. For the each potential the control electrode potential has been chosen to achieve the smallest beam crossover in the middle of the first accelerator cell. Calculations was based on the model of the already existing gun – electron injector in the linear accelerator. Then all calculations for the different anode voltages has been repeated for the biger cathode, that means – different cathode electrode geometry. The result to use in the further accelerator calculations has been achieved.

Methods of beam dynamics optimization of the first order are known and used for beam dynamics optimization*. These method are based on numerical calculation of gradient of functional estimating beam quality. In this report, method of optimization is proposed that includes numerical calculation of the second derivations (Hessian) of the quality functional. Proposed method is applied for a beam in RFQ channel. Control problem is formulated. The propblem consists in minimizing of functional depending on the beam density and on control functions. The control functions are the acceleration efficiency, the synchronous phase, and the channel apperture. For numerical solution the control functions are taken in parameterized form. The process of optimization represents a sequence of steps with use of the first and the second derivatives on parameters, during which the value of the functional decreases.

In the summer of 2013 the long shutdown was started dedicated to the deep upgrade of the wide range of subsystems. The main goal of the improvements is to reach or exceed design luminosity in the whole energy range from 200 MeV to 1000 MeV per bunch. The hardware of the accelerator complex consists of high current main field power supplies, low current power supplies for steering and multipole magnets, pulsed power supplies for channel's elements, RF subsystems, BPM and some other special subsystems (such as vacuum, temperature, etc.). The control system is based on CANbas, CAMAC and VME devices. The wide range of software corresponding to specific hardware subsystems forms complicated interacting system that manages all parts of the VEPP-2000 accelerator facility. Automation software is running on several TCP/IP connected PC platforms under operating system Linux and uses client-server techniques.

To operate a source of negative hydrogen ions an automatic distributed control system was developed. This system consists of master controller (Slab C8051F120) and a set of peripheral local controllers (PLC) based on microcontroller Slab C8051F350. Using an optical link between PLC and master controller there was created a system resistant to high-voltage breakdowns of the ion source. To control the system, a special programming language has been created. It includes procedures for checking the necessary parameters, setting the value of the physical quantities to simplify the experiment, verifying the lock status and protection. This system provides two programmable timers, as well as procedures in emergency situations, such as: lack of water, poor vacuum. It can be operated in semi-automatic mode: the script asks operator about preferable actions and then it continues actions depending on the response. All scripts are performed by master controller, and this makes system very rapid (for example system response time is 1 ms).

The media server was developed that implements the exchange of video and audio streams between control rooms for U-70 technological subsystems. Media server has the possibility of making changes into the intermediate video images to embed current technological information. The media server is implemented as a set of threads of execution, one for each video format conversion module. The media server is a chain of successive transformations of video and audio streams from one format to another: H264 - Y4M - Theora formats for video, PCM - Vorbis formats for audio. The final video and audio streams are encapsulated into the OGG container stream which is translating into the local network. OGG container has been chosen because of its completely open, patent-free technology and full support in HTML5. Any Web browser with full HTML5 support may be used as OGG stream consumer. The browser client program has written with tag "video" utilization. This allows for client to work on different platforms (Linux, Windows) and get rid of third-party video plug-ins.

A set of multifunctional units from National Instruments allows to monitor the oscilloscope signals with up to 50 Ms/s and to control the ions source power settings. The data acquisition devices programming performed in a LabView graphical environment. Algorithm and LabVew code for fast and safe "conditioning" of the ion source discharge gap and extractor gap from arcing and breakdowns were developed.

Fast magnetic beam raster system for INR isotope production facility is developed and implemented. The system enables to increase the isotope production efficiency by providing a possibility of using a higher intensity proton beam on the target of the isotope production facility. First experimental results of system application for irradiation of the targets are presented.

Designed neutron generator is designed for a neutron yield 1x10¹¹ neutrons / s in continuous mode and includes ion accelerator with an accelerating voltage, continuously adjustable in the range of 120-150 keV and a beam current of atomic deuterium ions up to 2 mA, and the target device, in which used Ti-T target different diameters. In addition to high and stable yield of neutrons in time when operating continuously generator provides pulsed mode of operation over a wide range of duration and pulse repetition rate. Pulsed neutron generator operation is performed by modulating the discharge current of the ion source. For this purpose, a unique system of power discharge, which allows for both continuous and pulse modes. In this case it is possible to produce a smooth adjustment of the pulse width of the beam current. Switch from pulse mode to DC promptly made with the remote control.

In this paper dynamics of processes in accelerator driven system (ADS) is considered. ADS reactor operates at subcritical level and the necessary neutron supply comes from the interaction of a charged particles beam with a heavy atom nucleus (spallation reaction). Mathematical model of dynamics of subcritical reactor controlled by linear accelerator is presented. Calculation results of transient processes in the reactor core taking into account fuel feedback. The reactor power level control is carried out through the regulation of linac current impulses frequency.

During last couple decades in Russia an interest in the electron-beam sterilization technology has been significantly renewed. The electron beam irradiation occurs at electron energies in the range from 3 up to 10 MeV with dose of 30 kGy. A special research interest is an exploring the possibility to reduce electron energy and dose characteristics upon foods irradiation.
