Entry number 383055

John and I went to the hall to check the BPM, John replaced the cover for
the BPMB so that it can absorb the RF noise, and we moved the BPM
receiver to the ground to avoid the potential noise.
For the simulated signal, seems it is a little bit better ,from 0.2mm to
0.14mm. see halog:

But the pedestal is still noisy, have double peak on both 90 gain and 77
gain(77 will be a little bit better than 90). We will test the BPM
without raster later during dilution run.Also John will go to the Hall to
check the noise on Wednesday.
