  Measurement of absolute Dee voltage results of the isochronous cyclotron U-400M at FLNR JINR by the X-ray technique will be presented. Measurements were made at the following frequencies of the resonance system: 12.8, 13.317, 15.012, 15.1 and 17.5 MHz. The modeling of X-ray spectrum was carried out by the software package FLUKA to accurately determine the maximum energy of X-ray spectrum. An influence of the absolute Dee voltage was estimated by the program Center.

  The main activities of Flerov Laboratory of Nuclear Reactions, following its name - are related to fundamental science, but, in parallel, plenty of efforts are paid for practical applications. Certain amount of beam time every year is spent for applied science experiments on FLNR accelerator complex. For the moment, the main directions are: the production of the heterogeneousμ- and nano-structured materials; testing of electronic components (avionics and space electronics) for radiation hardness; ion-implantation nanotechnology and radiation materials science. Basing on FLNR long term experience in these fields and aiming to improve the instrumentation, the accelerator department start the Design Study for new cyclotron DC130 which will be dedicated machine for applied researches in FLNR. Following the user's requirements DC130 should accelerate the heavy ions with mass-to-charge ratio A/Z of the range from 5 to 8 up to fixed energies 2 and 4.5 MeV per unit mass. The first outlook of DC130 parameters, its features, layout of its casemate and general overview of the new FLNR facility for applied science will be presented.

  Creation results of new beam monitoring systems during SEE testing on ISDE&JINR heavy ion facilities will be presented. Diagnostic systems of ion beam parameters were modernized at beam-lines for electronic tests at FLNR accelerator complex. Scintillation detectors based on flexible optical fibers, multichannel and 15-channel beam profile detectors and energy measurement system for the high energy beam-line based on U400M were created.

  Unknown energy of electron beam of linear accelerator was estimated by photo activation of only one activation detector - foil of natural indium. Three different photonuclear reactions were considered: 115In(gamma, gamma')115mIn, 115In(gamma, n)114mIn and 115In(gamma, 2n)113mIn. Ratio of saturation activities R(113mIn)/R(115mIn) and R(114mIn)/R(115mIn) were determined by standard gamma spectroscopy in electron energy region of interest (10 MeV - 23 MeV) using indium foils exposed in the FLNR microton MT25 bremsstrahlung beam. The choice of cyclic accelerator MT25, as a reference machine, was made due to the fact, that the energy of its electrons is known with accuracy not worse than 1%. Same ratios of saturation activities were determined after exposition of In activation detectors in photon beam of linear accelerator. The fact that both irradiations, by microton MT25 and accelerator, were performed in identical geometry using same target (3 mm of Tungsten) allowed us to estimate electron energy of accelerator by comparison of ratios of saturation activities obtained by both machines. Small variation in accelerator electron current was taken in consideration.
