“…In this framework, it is essential to develop high-performance framing cameras to meet the current needs of various applications and, in turn, several high temporal resolution frame cameras have been developed recently [23,24]. An ultrahigh-speed frame camera with 1280 × 1024 spatial resolution, time jitter of 5 ns and a minimum exposure time of 3 ns [25] has been implemented by Pioneer in Cameras and Optoelectronics (PCO). In addition, a high-speed multi-channel camera has been realized by Stanford Optics,1 achieving an ultra-high temporal resolution of about 0.2 ns.…”

The analysis of fast physical phenomena is a relevant tool in several fields including atomic physics and photochemistry. In turn, to record phenomena occurring on an ultra-short time scale, one needs an imaging system that can accurately capture the event. In this paper, we propose a novel ultrafast optical framing camera that achieves a spatial resolution up to 36.6 LP/mm while keeping a high temporal resolution of 3.25 ns using a digital delay generator. Our technique involves the splitting of light into four beams and their imaging on four ICCD cameras. In addition, the data transfer system is designed to combine data-streams from multiple digital ports into a single output, thus providing a compact user interface. The characteristic parameters influencing the temporal resolution of the image intensifier has been analyzed, and the framing camera has been experimentally assessed. Our results show that a temporal resolution of 3.25 ns and a spatial resolution of 36.6 LP/mm can be obtained. We foresee the use of our apparatus for inertial confined fusion.

“…The time-resolved measurement ability and the image frames obtained are critical limiting factors for the measurement system to obtain detailed information about the changes in the electron beam envelope. Based on our previously developed time-resolved measurement system [3][4][5][6][7] and the existing design principle, a composite measurement system for electron beam envelopes is developed by combining a high speed framing camera and a streak camera. Several panoramic images of the electron beam envelope at different times and the profile image of the center slit of the electron beam over the whole pulse duration can be obtained at the same time.…”

The time-resolved electron beam envelope parameters, including cross sectional distribution and beam centroid position, are very important for the study of beam transmission characteristics in a magnetic field and for verifying the rationality of the magnetic field parameters employed. One kind of high time-resolved beam envelope measurement system has recently been developed, constituted of a high-speed framing camera and a streak camera. It can obtain three panoramic images of the beam and time continuous information along the given beam profile simultaneously. Recently obtained data has proved that several fast vibrations of the beam envelope along the diameter direction occur during the front and the tail parts of the electron beam. The vibration period is several nanoseconds. The effect of magnetic field on the electron beam is also observed and verified. Beam debugging experiments have proved that the existing beam transmission design is reasonable and viable. This beam envelope measurement system will establish a good foundation for beam physics research.
