Cavity Beam Position Monitor

Based on the virtual instrument technology, a dedicated test system has been developed for cavity beam position monitor (CBPM). The system consists of commercial nanopositioning stage and its controller, the analog output DAQ card based on PXI and network analyzer. In the LABVIEW environment, software which implemented function of instrument control and data acquisition based on virtual instrument soft architecture (VISA) has been developed. Experimental results illustrated that the test system achieved positioning precision of sub micron which meets requirement of test of CBPM. Also it could serve CBPM signal processing system.

Improve Reliability

Accompanying the brilliance-upgrading project at the Photon Factory storage ring, the beam-position monitor (BPM) system has been renovated. The new system was designed to enable precise and fast measurements to correct the closed-orbit distortion (COD), as well as to feed back the orbit position during user runs. There are 42 BPMs newly installed, amounting to a total of 65 BPMs. All of the BPMs are calibrated on the test bench using a coaxially strung metallic wire. The measured electrical offsets are typically 200 µm in both directions, which is 1/2–1/3 of those of the old-type BPMs. In the signal-processing system, PIN diode switches are employed in order to improve reliability. In the fastest mode, this system is capable of measuring COD within about 10 ms; this fast acquisition will allow fast suppression of the beam movement for frequencies up to 50 Hz using a global feedback system.

A Current

A sensitive current-measuring system is required to construct a highly sensitive X-ray beam-position monitor (XBPM). A current–voltage converter (I/V) which can measure currents between 0.1 nA and 10 mA was designed, and the signal processing system of the XBPM was constucted using this I/V. This system was used in beamline commissioning. Beam-position data standard deviations of σ ≃ 3 µm for the bending-magnet beamline, and σ x ≃ 3 µm and σ y ≃ 1 µm for the insertion-device beamline were obtained during the beamline commissioning.
