The article describes the waveform monitoring complex of the linear induction accelerator designed for radiographic experiments. The equipment of the complex allows recording waveforms of hundreds of pulsed signals with duration of tens of nanoseconds to tens of milliseconds, which provides comprehensive information on the operation of the accelerator. The article addresses a wide range of issues: architecture of the waveform monitoring complex, types of primary sensors, techniques of analog signal transmission with low distortion, hardware, software, and methods of data processing.

A system for diagnostics of the electron-beam position in the channel of the microtron–recuperator (MR) of the Novosibirsk free-electron laser is described. The position of the beam is measured using electrostatic BPM stations that are installed in different parts of the vacuum chamber on the path of the beam along the accelerator channel. The features of the operation of the multiturn MR resulted in the necessity to develop an algorithm for measuring the beam position that differs from the algorithms that are used on other charged-particle accelerators. This system can be used to measure the positions separately of both accelerated and decelerated beams that are simultaneously present in some segments of the MR.
