	To provide successful operation of SASE XFEL the radiation detectors should operate in wide dynamic range from the level of spontaneous emission to the saturation level, in wide wavelength range from 0.05 nm to 0.16 nm for SASE1 and SASE2 and from 0.4 nm to 4.4 nm for SASE3. High relative accuracy of measurements is crucial for detection of a signature of lasing, tuning of amplification process, and characterization of statistical properties of the radiation. The XFEL radiation detector based on micro-channel plates (MCP) meets these requirements. Two types of the photon detector are used for measurements of the pulse radiation energy and the image of the photon beam. The dynamic range of photon pulse energies is between 1 nJ and 10 mJ. This applies to spontaneous and FEL radiation. The relative accuracy of pulse energy measurements is better than 1%. The visualization of a single bunch in a train, or average image over the full train will perform by the MCP imager at a spatial resolution of 30 μm.

	The approval of the Dmitrovgrad project - the first Russian hospital center of the proton therapy was announced in 2010. The JINR-IBA collaboration have developed and constructed the proton cyclotron C235-V3 for this center. We plan to assemble this cyclotron in JINR in 2011 and perform tests with the extracted proton beam in 2012. This cyclotron is an essentially modified version of IBA C235 cyclotron. Modification of the extraction system is aim of new C235-V3 cyclotron. The new extraction system was constructed and tested. The experimentally measured extraction efficiency was improved from 60% for the old system to 77% for the new one. The new field mapping system was developed for the C235-V3 cyclotron. It system consists of the axial field mapping system and an additional system applied for radial field Br measurements. One of the goals of the cyclotron improvement is the modification of the sector spiral angle for reducing of coherent beam losses at acceleration. The coherent beam displacement from the median plane is defined by the vertical betatron tune Qz. An increase of the vertical betatron tune permits to reduce the coherent losses at proton acceleration.
