  • Next message: Stephen J. Sanders: "Re: NIM paper comments"

    Folks-
    A few comments on the NIM paper to join with the other
    comments of all the enthusiastic and careful readers.
    Most of the stuff below is small
    detail. The one thing I feel strongly about is a missing
    few sentence Summary at the end. This could say at least
    that the spectrometers/DAQ/detectors are operating satisfactorily in the
    present run.  Kris and helpers  have really done a nice job.
    Thanks-
                        Chellis

    page 2, 1st para left col: "Rapidity...and approaches v/c.."
                 should be "..approaches v(parallel)/c.."
    
            4th para 4th line: The other PRESENT RHIC experiments...
            same paragraph: MSR should be MRS
            5th para ...5.6 msr.... on page 5 bottom 6.5msr. Let's
               just pick something consistent.
    
    page3 1st para left col: "..thermodynamical.." why not something
                more general  "...reaction dynamics.." for example.
    
    page 5 last para right col: 6.5 msr as noted above,
                             MSR should be MRS
           Figure 3 caption ...yellow yoke of D2 IS VISIBLE.
    
    page 9 1st para right Col: ..velocity of 1.6 cm/us... requires us
                      to identify the gas mixture/pressure also. Let's
                      move the velocity to the next paragraph down.
            same para:  Let's add a sentence that there is a gating
                      grid also which is discussed later since
                      this paragraph describes the physical structure
                       of the TPC and Figure 8 and 9 show the grid.
    
    page 10 last para left col: "The signal.." This paragraph continues
                       the description of the drift monitor and needn't
                       be separated from the one above it.
    
    page11, 3rd para left: 1st sentence "...have a TPC active...".
               delete .".in.."
    
    page 14, 1st para left: particle identification also depends
              on momentum resolution.
              same para: Add something like: "Figure 29
              discussed below demonstrates the particle identification
              capability achieved."
     same page "Cerenkov Detectors": Why not use a subtitle here
                   to separate C1 and RICH discussions
               Figure 14: "Mirror" and "Light Funnel" text
                           too small.  If we can't fix figure
                           can we rewrite caption?
    page 15 2nd para left: Add RICH subtitle?
    
    page 16 Figure 18: It's hard to see where the arrows
                    pointing to the tiles or Si strips goes.
                    Is this easy to fix?
    
    page 17 2nd para left: ...The discrete component..., I thought
                         "discrete components" meant individual
                        transistors but I'm not sure.
    
    page 18 1st para left: "...the order of 1 cm." how about
                        .. approximately 1 cm. I think order means
                         a factor of 10.
    
    page 20 1st para left: ..heating of nuclei by photons.." does
              this refer to the "excitation of nuclei by virtual
              photons from the Coulomb field."
            2nd paragrph left "..At RHIC energies evaporation
                  neutrons" should we add "..from spectators.."?
    
    page 21 2nd para left,last line: "..have the same number of wounded
                      nuclei"  "wounded nuclei" presumes
                       more than a simple geometric description.
                      How about "...since spectator nucleons are
                      produced from both colliding nuclei.
    
    page 21 last para left: "...IP..." Have we identified this
                            somewhere?
            1st para right last sentence is FEH defined?
            2nd para right: is FEE defined
                same para:   "For  the YEAR 2000 running...."
    page 22 1st para last sentence: "..will be implemented
                     at LVL0 or LvL1." Let's not say how we will
                     implement it.  We could also strike the sentence.
    
              same para 1st sentence: ",..dissociation AND
                peripheral....."
    
    page 23 footnote: "....at that speed though..." some typos
               here. Is "race" "rate"?
    
    page 24 last para left: "..that are interrupted" delete
               "being"
    
    page 27 Figure 25.  Can't read coordinates. Can we use larger
                    print or add explanation to figure caption.
    
    page 29 1st para left:" ..timing uncertainty of 30
                    psec"  seems too small to matter, but
                    momentumn resolution does which we consistently
                    ignore in PID by time of flight.
    
    page 29 2nd para left: Have we identified "BFS"?
    
    page 29 Should we add a few line Summary?
