چکیده

A hardware system that acquires and stores a large buffer of bunch-by-bunch 16-bit data has been realized. A high resolution (up to 16-bit) analog-to-digital converter (ADC), or bank of ADCs, samples the analog signal at the bunch frequency. The digitized data is fed into a Field Programmable Gate Array (FPGA), which contains an interface to a bank of Double Data Rate SDRAM (DDR) type memory. With appropriate data bus widths, the FPGA bursts the ADC data into the DDR fast enough to keep up with the bunch-by-bunch ADC data continuously. The realized system demonstrates continuous data transfer at a rate of 1GByte/sec, or 16-bit data at 500MHz, into a 64MByte DDR. This paper discusses the implementation of this system and the future of this architecture for bunch-by-bunch diagnostics.

TOPOS: A new Tool for Beam Position Measurements at SIS18

The new Tune, Orbit and Position Measurement System for the SIS18, called TOPOS, is a replacement for the present POSI BPM System. Currently TOPOS is installed in parallel and uses the same analogue amplification chain as POSI. TOPOS consists of 12 Libera Hadron units [1] for front-end processing. The Libera stations sample the four analog plate signals of a BPM pick-up with four 14 Bit ADCs at...

Implementation of a Data Acquisition System for 2×2 Fiber Optic Taper Array Coupled Digital X-ray Detector

Fiber optic taper (FOP) array coupled digital x-ray detector can be an ideal choice for large area high resolution x-ray imaging, but its data acquisition system is a challenge, for the reasons such as restrictions of hardware design due to the shape of the FOP array, long distance control requirement in x-ray environment, and arrangement of data transmission sequence among multiple CCD/CMOS im...
