	The architecture and capabilities of free electron laser radiation spectrum measurement system described in details in this paper. For execution of the measurements the monochromator and step-motor with radiation power sensor are used. As the result of the measurements, the curve of spectrum of radiation is transmitted to control computer. As this subsystem is fully integrated to common FEL control system, the results of measurements – spectrum graph, average wavelength, calculated radiation power, are able to transmit to any another computer on FEL control local area network and also on user stations computers.

	To study the synchrotron terahertz emission superconducting (YBCO) film detectors are used with the intrinsic response time in the order of a few picoseconds. For fast, continuous sampling of the individual THz ultra-short pulses a novel digitizer system has been developed. The system consists of detector, wideband low-noise amplifier, fast pulse digitizer board, back-end readout board. High-end graphic processing units (GPUs) perform real-time data analysis. Four samples with 12 bit are recorded in parallel for each fast pulse with programmable sampling times in the range of 3 to 100 ps. A new bus master DMA engine connected to PCI express endpoint has been developed to ensure a continuous high data throughput of up to 4 GByte/s. This heterogeneous real-time system architecture based on FPGA and GPU has successful been used for on-line pulse reconstruction and evaluations and calculates the peak amplitude of each pulse and the time between consecutive bunches with a picosecond time resolution at ANKA. A Fast Fourier Transform (FFT) is performed on-line for the frequency analysis of the CSR undulations.

	The radiation monitoring system of J-PARC was constructed as a part of safety facilities. Thus, it has been operated independently from the main accelerator control system. In fact, the radiation monitoring system consists of two subsystems. The first subsystem developed by JAEA, which covers Linac and RCS ring, is PLC-based. We add a FL-net module to this subsystem to enable one-way data transfer to the accelerator control system. Here FL-net is a device-level communication network using UDP/IP, defined by a Japanese consortium. The second subsystem developed by KEK covers MR ring. It is a CAMAC-based DAQ system. Since this subsystem was difficult to extend, we made signal branches from radiation monitors, and fed them to a new PLC-based DAQ system. As same as the first subsystem, a FL-net module is used for one-way data transfer. In 2013-2014, integration of two subsystems has been carried out. Now radiation monitors can be supervised with the accelerator control system. As a result, accelerator operators can check radiation levels much easier than before. We understand that this is a significant improvement to realize safer operation of J-PARC accelerators.
