Here is a preliminary list of end-of-spill data
that the DCS might read out from an Accelerator Division 
server. A new and faster system being developed
for D-zero and MiniBooNE and will replace the socket
read out we now use. I put together
this list by polling beam line physicists in MINOS.
So far it looks like about 1239 words, but I expect
other candidates to trickle in.  

 1. Proton Count, probably 2 toroids.
 2. Last 2 Beam Position Monitors (BPM's)
    2 x's and 2 y's
 3. An OTR (Optical Transition Radiation) monitor.
    There would be 2 of these. Each has a 20 X 20
    CCD pixel read out. This implies 2 X 400 words.
    This is not yet in the baseline.
 4. Two thermocouple monitors (left & right) to 
    detect beam wandering. (Couple of minutes to
    reach equilibrium)
 5. Two words for Budal monitors on the low energy target
 6. 4 words for the horn currents.
 7. 4 words for the horn timing.
 8. 2-3 words for B-dot coils in horn fields.
 9. 1 word for the horn microphone. (Not in current WBS estimate)
 10. Flow meter for water. How many?
 11. Water temperature. How many?
 12. Water level in tank.
 13. Temperature in the target pile.
 14. Cooling air temperature: IN and OUT
 15. Decay pipe vacuum.
 16. Beam loss monitors. How many?
 17. Exhaust stack monitor for air activation.
 18. Decay pipe temperature. How many?
 19. Absorber temperatures. 8 Al pieces, 1 steel
     that are water cooled. 3-5 pieces of steel
     not water cooled. 
 20. Three muon beam monitoring chambers (96 words
     per chamber). Possibly a hadron chamber with
     another 96 words. The word count will be higher
     for some spills when we also take pedestal data,
     electronics calibration data, and voltage-plateau
     data for the monitoring chambers.
