Abstract


Hefei Light Source existence of the beam horizontal rail slow drift phenomenon , affecting the stability of the quality of the light source . The beam horizontal track slow-moving horizontal displacement of the beam position monitor (BPM) . The beam vacuum duct due to the light irradiation of the synchrotron radiation and the ambient temperature changes and thermal expansion exhibited in the horizontal direction of displacement , and attached to the vacuum tube over the beam position detector (BPM) is also generated with the vacuum tube deformation horizontal displacement , this will cause the BPM incorrectly positioned beam orbit position . When the wrong track position data is fed back to the slow orbit feedback system , the system will be forced to correcting the beam horizontal rail , so that the track is forcibly moved with the BPM position change . In order to suppress the beam horizontal orbit drift developed Hefei Light Source BPM vacuum chamber displacement monitoring system is used to real-time monitoring of the ring 24 BPM horizontal displacement of the vacuum chamber and displacement data back to the slow orbit feedback system makes slow orbit feedback system is able to calculate the correct level of the beam orbit position , and thus be able to correct correction track , the track is not BPM horizontal direction is constantly changing displacement impact . BPM vacuum chamber displacement measurement tools 24 RF203 grating displacement sensor by the RS485 bus network parallel connection of IPC on the BPM vacuum chamber displacement monitoring system . IPC by polling read 24 grating displacement sensor measurement data , and data via Ethernet Channel Access Server release to Hefei light source control system . Displacement Monitoring System for Hefei Light Source BPM vacuum chamber will effectively suppress the beam horizontal orbit drift , and improve the quality of the HLS run . In this thesis the National Natural Science Foundation funded project ( 1,027,506,210,675,118 ) .
