1, BPM

We took a Bull's eys scan on May 4th 2011 [1]. Both BPMA and BPMB had been scaned at different points along BeO target plane.

The Bull's eys scan run info is:

Where BPM info are gethered from EPICS since the reading from Harp data is not reliable due to the true that the Harp has not been surveyed for the long time and there are some unknown offsets.

Here is the calibration resut of BPM: HRS-R

2, Raster

Raster signals were sent into both HRS, so the map of raster ADC connection should be different for Left and Right.
