Stripe camera with stable imaging performance and stripe camera system

Abstract

The invention relates to a stripe camera with a stable imaging performance and a stripe camera system. In the stripe camera, a first switching power supply is connected with a photocathode P / C; a second switching power supply is connected with a grid M; a third switching power supply is connected with a first focusing electrode F1; a fourth switching power supply is connected with a first anode A1; a fifth switching power supply is connected with a second focusing electrode F2; and a second anode A2 and a phosphor screen P / S are grounded. The first switching power supply, the second switchingpower supply, the third switching power supply, the fourth switching power supply and the fifth switching power supply independently provide voltage. According to the invention, five independent switching power supplies are used for independent power supply, which overcomes the problem of instable series voltage dividing of resistors in the prior art; shielding layers are arranged on a power supply box and in an equipotential area of the stripe camera, so that interference of an external electromagnetic field is avoided; and a test result is accurate.

Description

technical field [0001] The invention relates to the field of streak cameras, in particular to a streak camera with stable imaging performance and a streak camera system. Background technique [0002] Streak camera, also known as scanning camera, is an important diagnostic instrument for obtaining continuous temporal and spatial change information of ultrafast optical radiation. It plays an important role in scientific research and technology fields such as physics and high energy physics. In particular, it is an indispensable diagnostic instrument for obtaining implosion dynamics and implosion compression information in laser-driven inertial confinement fusion, and obtaining images of continuous spatiotemporal changes in plasma radiation. With the deepening of research on streak cameras, it is required to "refine" the time, space and energy spectrum diagnosis of streak cameras, and it is required that streak cameras not only have high temporal and spatial resolution, large ...
