keyword=recorded raster value at 6 GeV overflowing ADC ?looking at the raster current, I think the ADC is getting some overflows ( 14th bit ) since the raster current is bigger at 6 GeV.
We could put an attenuator to keep the BPM calibration or reduce a bit more the ADC gate but we would need to change the constants for the BPM as well. Though this does not explain the :
ange. Setting beam position to nominal values
Warning in
Will have to check if there are other things plugged in the ADC. According to previous HALOG 247221 lower rates does not help. So a sizeable amount of data has no position, might need to check/improve the code to see if we can retrieve the position.
In THaRaster.C,
if (fNfired!=4) {
Warning( Here("Decode()"), "Number of fired Channels out of range. Setting beam position to nominal values");
}
