Description
Technical Field
The invention belongs to the technical field of plasma diagnosis, and particularly relates to a rotary platform for calibrating multi-space-channel small-hole imaging detection equipment.
Background
A device for detecting neutral particles emitted from the interior of the plasma in a fusion plasma apparatus,
known as Neutral Particle Analyzer (NPA). In the field of fusion plasma research, NPA is a key diagnostic tool for high-energy ion physical analysis, ion temperature measurement, fusion reactor fuel density ratio (T/D) measurement.
In principle, the NPA system generally strips electrons outside the neutral particles at the stripping unit, performs energy/momentum analysis on the ions by using a high-voltage electric field/a strong magnetic field at the analysis unit, and finally measures the ions at the detection unit by using a detector sensitive to charges. In order to meet the measurement requirements, the whole system must be placed in a vacuum environment and maintained in vacuum by an air pump set; in order to keep the analytical electric/magnetic fields undisturbed, the outside of the system is typically surrounded by a thicker layer of shielding soft iron. Because of the vacuum and shielding requirements, the mass of the NPA system is generally larger, and the mass of the system body (excluding the pump set and the pipeline) reaches 160kg through a plurality of neutral particle analyzers CP-NPA developed by the nuclear industry southwest physical institute and the Russian about flight technology physical institute.
Before being installed on a device for formal use, the NPA must be calibrated to calibrate the detection efficiency, detection range, energy resolution, etc. of each spatial lane at a specific stripping parameter (e.g., the air pressure of the stripping unit) and specific energy particles. The multi-channel NPA generally adopts a small hole imaging mode, neutral particles integrated on different chords on a circular section of the plasma during measurement are shot into detectors at different positions in the NPA from the same slit along different angles, and the effect of spatial resolution is achieved. To index multiple NPAs, the index beam must be made incident from different angles centered on the entrance slit. However, the calibration source system is generally realized by adopting a low-energy accelerator with adjustable energy and beam intensity and matching with a neutralization chamber, the complexity and the quality of the system exceed those of an NPA, and the calibration source system is generally difficult to move after the beam is stabilized through the adjustment.
