Presented work describes the modulator of electron current of the industrial accelerator ILU-10. The main target of building of the unit is decreasing of energy spectrum and stabilization amplitude of the accelerated current. The base of unit is HV linear DC amplifier (up to 5000V) with power (up to 5 A) MOS-FET output stage. It allows to create feedback and stabilize either current or energy of the beam. Also this unit has mode for tuning any shape of beam current and energy. Unit has microprocessor control circuit which provides useful link with computer control system of accelerator and if needed provides the handle operation and indicates main parameters of electron beam.

General principles of automation of superconducting multipole magnets (wigglers) delivered to centers of synchrotron radiation in Germany, Canada, Italy and other countries are described. The following items are considered in the presentation: - monitoring of the basic parameters of a wiggler (temperature distribution, helium consumption, pressure in a cryostat, etc.); - setting and maintaining of the main field (currents); - developing of users interactive codes; - modification of the software according to requests of customers. Main results of works are presented.

3.5 Tesla 49-pole superconducting wiggler with 16 mm magnetic gap and 60 mm period for Diamond Light Source (England) has been fabricated in Budker INP. A first wiggler test was carried out in bath cryostat in BINP on July 2005. The first wiggler test in own cryostat was performed in BINP on January 2006. This test includes field integrals measurements with stretched wire method and field measurements with hall probe. All this measurements was repeated on April 2006 in DLS. Design of special magnetic measurement system with anti-chamber and main wiggler tests results are presented in this paper.
