        Hi, Eric,

        few things, mostly typos

sl 2    ">" "100K" (looks ugly that the number is in the next line)

sl 3    "cham" -> "charm"
        "higher quark-jet fraction at RHIC" doesn't make enough sense
        unless you add "than at LHC" (and maybe the corresponding
        plot for LHC could be added?)

sl 4    "Calorimetery" -> "Calorimetry"
        "ofHadronic" -> "of Hadronic"
        "flavour" -> "flavor" (we are in the US...)
        Personally, I think tracking is not only "essential
        for heavy flavor", but also for jets (particularly
        in light of the low granularity)

sl 6    "scinitillating" -> "scintillating"
        "boundries" -> "boundaries"
        the bottom right picture is confusing w/o a caption

sl 8    "with the outer serving as the flus return" ->
        "with the outer also serving as the flux return"
        (this is the second time - first on sl 5 - when the
        audience might think all the HCal does is return
        the flux :-)
        "wave-shifting" -> "wavelength-shifting"
        "each tile is readout" -> "each tile os read out"

sl 9    "Signal... are passively" -> "Signals... are passively"
        "azsembly" -> "assembly"

sl 10   "were measure in" -> "were measured in"
        "senative" -> "sensitive"
        right figure captions overlapping

sl 11   (200 -> see Craig's correction)
        "Atomaki" -> "Atomki"

sl 12   "Temperature variation can form" awkward, I think
        what you mean is "Temperature variations can be caused
        by" or "can come from"

sl 14   "resultin" -> "result in"
        "64 devices" maybe "64 SiPMs" is clearer

sl 15   "Vop" -> "V_{op}" (four times)
        "constriction" -> "construction"
        maybe here it would be appropriate to give a typical
        slope (how sensitive we are to variation in V_op)
        and also a thermal coefficient

sl 17   "adjust" -> "adjustment"
