Hi Sourav,
<div class=""><br class="">
</div>
<div class="">Thank you for putting together this nice draft. I have a few minor comments:</div>
<div class=""><br class="">
</div>
<div class="">General: Page numbers are not visible on all the pages.</div>
<div class=""><br class="">
</div>
<div class="">p.6 Please get the drawing of the detector mechanics as actually built from Pietro. The one you have on the right is obsolete.</div>
<div class=""><br class="">
</div>
<div class="">Suggest: “Design with only foils present in the active area. Mechanical support structure…"</div>
<div class=""><br class="">
</div>
<div class="">p.7 We were hoping to run with 120 GeV proton, not pions. I agree that we need to put a statement on the mechanical instability of the drift foil.</div>
<div class=""><br class="">
</div>
<div class="">p.11 Use hyphens: Double-sided Thin-Gap to make it easier to read</div>
<div class=""><br class="">
</div>
<div class="">p.12 The various labels on the designs need to be adjusted for the smaller size of the graphics. Right now they are a jumble.</div>
<div class=""><br class="">
</div>
<div class="">Also: -> Design o<u class="">f</u> frame structure for GEM and <u class="">
drift</u> foil stretching</div>
<div class="">
