Description

ELVA-1 recently designed this new series of BWO sweepers. This new SGMW series is fully packaged sweeper series. The sweeper consists of external module with BWO-X series and power supply. The device contains all the electronic circuitry and power supplies required to provide the operation of BWO. PC compatible microcomputer integrated into the device provides operating control of the system. The sweeper self-tests at turn-on. BWO tube is fully protected against improper voltage connections. High voltage monitor is built-in. There is input for control of frequency by means of an external voltage. Phase locking feature is provided. One power supply can be used with different BWO.

Remote module of BWO Sweeper

The new device design has a number of advantages compare to its predecessor (G4-143x series of BWO generators).  Particularly, there is a remote module with BWO tube that allows using it at hard-to-reach places within tokamaks and other types of huge equipment plant in research centers. With the remote BWO module, the ELVA-1 sweeper itself can be installed quite away (up to 3m), allowing more comfortable conditions to organize a scientist’s workdesk. Another great advantage of new series of BWO sweepers is its new power supply unit that allows feed up to few BWO tubes with different working frequencies. Thanks to this new power supply, the total cost for wide-band sweeper can be well reduced.
