	A new electron source for the Race-Track Microtron Recuperator is being developed by BINP SB RAS. It will increase average beam current and brightness of synchrotron radiation. Instead of the static 300kV electron gun operated now we are developing RF gun with the same energy of electrons. This RF gun consists of RF cavity with a gridded thermo cathode mounted on the back wall. RF cavity is driven by a 60 kW generator with last stage equipped by GU101A tetrode tube. Operational frequency of the cavity is 90.2 MHz. It is equal to the second subharmonic of the Microtron RF system frequency. A set of low power electronics controls amplitude of the cavity voltage and its tuner. This system, including a diagnostics beam line, has been installed to serve as a test bench to test the RF cavity and for beam dynamics studies. In continuous regime the designed 300 kV voltages at the acceleration gap is obtained. This paper summarizes the first test results of the cavity in this configuration.

The RTM magnetic system consists of two four-pole end magnets with the main field level about 0.8 T, one quadrupole and four beam extraction dipoles. As a source of the magnetic field in these magnets a Sa-Co rare earth permanent magnet material is used.

The performance of the magnetic system of a 12 MeV electron race-track microtron (RTM) which is under construction at the Universitat Politècnica de Catalunya (UPC) is described. The RTM magnetic system consists of two four-pole end magnets with the main field level about 0.8 T, one quadrupole and four beam extraction dipoles. As a source of the magnetic field in these magnets a Sa-Co rare earth permanent magnet material is used. This helps to get a quite compact design of the RTM and allows to place the magnetic systems in a high vacuum environment of the accelerator vacuum chamber. We discuss results of numerical simulations of the tuning of the end magnets by mean of special tuners and describe their engineering design which permits to assemble the magnets and fix the Sa-Co blocks without gluing. Also a method and results of magnetic field distribution measurements and magnet tuning are reported.
