Trigger Pickoff Scope Pictures -------------------------------- Original Rev. 16-AUG-2001 Current Rev. 12-MAY-2003 This file describes the Trigger Pickoff scope pictures in the directory: http://www.pa.msu.edu/hep/d0/ftp/l1/cal_trig/pictures/trig_pickoff/ For a given scope capture, the files are named: tek00n00.eps & pdf the scope picture tek00n00.csv the spreadsheet data for the non-inverted side of the differential signal tek00n01.csv spreadsheet data for the non-inverted - inverted signal display, i.e. the "math" display. Where the "n" in the above filenames is the capture number. "n" = 1, 2 are EM from TT +1,17 (eta,phi) "n" = 4, 5 are Had from TT +1,17 "n" = 6,7,8 are Had from TT +8,17 "n" = 9,10 are EM from TT +1,32 \ "n" = 11,12 are EM from TT +8,17 | "n" = 13,14 are EM from TT -8,17 | NEW THIS WEEK "n" = 15,16 are HAD from TT -8,17 / Each scope picture shows: Top, Violet color: Time of the actual beam crossings in the center of the D-Zero detector. Red color: Math, the non-inverted signal minus the inverted signal. Scale is about 2 Volts differential equals 62 GeV Et. Yellow Color: Non-Inverted side of the differential line. Bottom, Blue color: Inverted view of the Inverted side of the differential line. The delta time display on the right is the time from the actual BX in the center of D-Zero until the nominal peak of the trigger pickoff signal. 19-Mar-2003 tek01700.csv waveform data from TT -1,17 EM noise tek01700.tif scope display of this waveform data tek01701.tif Fourier Transform of this waveform data tek01800.csv waveform data from TT -1,17 HD noise tek01800.tif scope display of this waveform data tek01801.tif Fourier Transform of this waveform data tek01900.tif scope display of TT -4,32 EM L2_Acpt.

Data for the last column (everything back ON) was collected that evening at about 8 PM. Everything OFF means: SMT and CFT Sequencers platform Central OFF L1 Muon platform East was OFF All DFE's platform Center and West were OFF FPD platform West was OFF Mixer was OFF All Clock to All AFE's were OFF Scope FFT Pictures The ".tif" files are in: www.pa.msu.edu/hep/d0/ftp/l1/cal_trig/pictures/trig_pickoff/ as filename "tek023xy.tif". 17:18-APRIL-2003 Noise Study This was done using -8,15 HD from the CTFE LEMO and using a Radiation Monitor signal that Ron brought down from the 3rd floor. These files are in: www.pa.msu.edu/hep/d0/ftp/l1/cal_trig/pictures/trig_pickoff/ as filename "tek024xy.tif". 00.tif Rad Monitor with SMT readout Noise gated out Thursday 01.tif Rad Monitor with SMT readout noise Thursday 02.tif -8,15 HD CTFE Lemo during Physics running Thursday 03.tif -8,15 HD CTFE Lemo between stores Cal PreAmp OFF Friday 04.tif -8,15 HD CTFE Lemo between stores Cal PreAmp back ON Friday 23:24-APRIL-2003 Noise Study while Muon Detector power was off and the Iron Open. Normal setup of plugging the scope/spectrum analyzer directly into the BLS Cable and using only the inverted side of the Trigger Pickoff signal. All of this study is looking at the 13.2 MHz line. The 3 TT's that we have been using to look at 13.2 MHz are: -4,26 HD, -8,15 HD, +12,12 23-Apr-03 8:30 PM Before test started TT Amplitude File ------ -------------------- -4,26 1.2 mV 00 -8,15 2.0 mV 01 +12,12 0.4 mV 02 +1,2 1.7 mV 03 +4,31 0.7 mV 04 -12,31 0.5 mV 05 -9,8 4.0 mV 06 All TT's except of -9,8 are used to look at the 13.2 MHz line with the scope set to 5 mV/Div. TT -9,8 is used to look at the 10 MHz pickup with the scope set to 10 mV/Div. 24-Apr-03 9:30 AM 24-Apr-03 21:15 PM South and East Iron Open Everything Closed up All PDT's ON and Running TT Amplitude File Amplitude File --------- ------------------------ -------------------- +1,19 HD 0.5 mV 07 1.0 mV 11 +8,16 HD 2.0 mV 08 2.0 mV 12 +12,13 HD 1.4 mV 09 1.7 mV 13 +1,2 HD - 10 These files are in: www.pa.msu.edu/hep/d0/ftp/l1/cal_trig/pictures/trig_pickoff/ as filename "tek025xy.tif". 12-MAY-2003 Survey a number of TT's to record what the base line noise looks like. This was done on 9-MAY-2003. The files from this are in: www.pa.msu.edu/hep/d0/ftp/l1/cal_trig/pictures/trig_pickoff/ as filename "tek020xy.tif" or "tek020xy.csv". files 00 and 01 .tif and .csv are from -9,17 EM files 02 and 03 .tif and .csv are from -9,17 HD files 10 and 11 .tif and .csv are from -12,15 EM files 12 and 13 .tif and .csv are from -12,15 HD files 20 and 21 .tif and .csv are from -4,14 EM files 22 and 23 .tif and .csv are from -4,14 HD files 30 and 31 .tif and .csv are from -1,17 EM files 32 and 33 .tif and .csv are from -1,17 HD This was the standard setup looking only a the inverting side of the TT signal.
