Presentation Transcript

  1. #3121 • Corrections to previous file \\Dlfiles03\alice\Analysis\Period 14 data\AP_period13and14\BPM\3121\3121.pptx • 1) remove “transient” (100 bunches) by BEFORE subtracting train mean • 2) plot absolute fourierAmplituderather than power. • 3) correct the indexing of the fourier components (previously, all my fourier spectra were shifted by + 10 kHZ from the correct values)

  2. 3121 AR1-BPM-01 2216 BPM_Data_EMA-DIA-BPMC-02_2048_6-6_117-107_1_15pC.dat" fig 2. in IBIC 2012 paper

  3. 3121 AR1-BPM-01 Fourier fig 4. in IBIC 2012 paper mean was subtracted from x , y, charge, before taking DFT

  4. Removing “Transients” • Now we take off the first 100 bunches from the raw data • Then subtract the mean

  5. Fourier with new analysis OLD, IBIC NEW DFT with corrections IBIC fig 2. DFT of mean-subtracted-data identical to slide 3
