Run 4

Organisation

• updated run/analysis plans
•  
• archiving
• at PSI, see run3
• at LBL, tr4
• use arctdc, valid for normal and cmp files
• arcfadc

• electronics, see run3

• run documentation
• electronic runbook contains
• list of  runs (run4.ps)
• A brief summary of run groups is given here.
• data tapes
• data quality checks
• fadc
• tdc

 

 Programs

• fadc
• a20 ( analysis of run2, updated from alpha)
• file distribution: make ftp
• make (set write rawsub in Makefile)
• mu_ana

input fort.15, correct DISKs automatic, possibility to use tape directly but open errors

fifo2
ftest

icont,ilimit
icont=1 no raw fadc in hbook file
icont=2 fadc raw data in hbook file
ilimit=0   all events
      =nn  nn events will be analyzed

data file  ex: mup99b.133 or fifo2

hbook file  ex: ftest
 

• tdc
• tr4
• file distribution: make ftp
• make
• upgrades
• Tom's fast tracking
• new make_buf
• selmu option
• additional special spectra (30 each)
• all_tdc includes buffering

esel variables are used for event display and/or for capture/Alvarez n-tupling
*       esel(1)      # tpc (>0 turns on selection), forces ntupling
*       esel(2)      del z1
*       esel(3)      del z2
*       esel(4)      del t1
*       esel(5)      del t2
*       esel(6)      required candidates
*       esel(7)      high/low ratio > esel(7)/100.
 

input file: dev=tape or filename

output filename
 

Analysis and Work

fadc analysis

• kaon on a20
• analyze from dlt: fifofadc i1 i2

where i1=run skips, i2=# runs to analyse
device in fort.15 must be fifo2
• cp to disk: diskfadc i1 i2

i1,i2 same as above, then run mu with suitable fort.15
• event display
• first mu_ana with

fort.15    11  500
fort.15    12  500  invokes mu_select mechansm
• paw: pall ftest11.35
• paw analysis
• paw: dall (working, but has to be tuned)

tdc analysis

• RUN4: pdsf batch on tr4
