<div>Dear Carlos,</div>
<div><br>
</div>
<div>That looks generally good. I agree with Holly’s comments. Here are a couple more.</div>
<div><br>
</div>

<div><br>
</div>
Slide 14: I suggest adding the line:
<div>Measure F2_n as a function of initial momentum</div>
<div>Indicate somehow that you detect the e’ and the p</div>
<div>tag <b>backward</b> protons</div>
<div><br>
</div>
<div>How does F2_n depend on initial neutron momentum?</div>
<div>
<ul class="MailOutline">
<li>Measure spectator-tagged DIS d(e,e’ p_s)X</li><ul class="MailOutline">
<li>tag backward protons 300 < 600 MeV/c</li><li>new Large Acceptance Proton detector</li></ul>
</ul>
<div>Which nucleons are modified?</div>
</div>

</div>
<div>Slide 18: too many words</div>
<div>
<ul class="MailOutline">

<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">Hi Carlos,<o:p></o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;"><o:p> </o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">I have a few comments:<o:p></o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">Slide 7: You haven’t said yet what is SRC<o:p></o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">Slides 8-10: You mention the back-to-back momentum, but you might mention that it is large, and then also mention that in position space, they are overlapping
or close together.<o:p></o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">Slide 12: You may need to write something on the slide more about the kinematics of the plot or what the take-away is.<o:p></o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">Slide 14: It may be helpful to replace the green line with an arrow or something as it’s a little unclear looking at the diagram that the recoil proton
is the proton from the reaction (so show that it is a result of the reaction).<span class="Apple-converted-space"> </span><o:p></o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">Slide 15: I think you want to keep the jet spray on all the red neutrons so it doesn’t look like it disappears with the increasing spectator momentum<o:p></o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">Slide 21: You can remove my picture. The GEMs were made by UVa and I’ve had some support from other students and postdocs that I don’t want to leave out.<o:p></o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;"><o:p> </o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">I think you never really described F2 on any slide….you might have it described somewhere at the beginning just so it is clear what it depends on and what
we measure.<o:p></o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;"><o:p> </o:p></span></div>
<div style="margin: 0in; font-size: 12pt; font-family: Aptos, sans-serif;"><span style="font-size: 11pt;">Slide 27: You should mention that we have had GEM support from UVa (they are making a spare for us now, specifically Huong Nguyen). Crucial support also
comes from Ching Him Leung (JLab postdoc-in fact he is the GEM expert right now), Asar Ahmed (UVa postdoc), Vimukthi Gamage (UVa student), Xinzhan Bai (now JLab staff). You could highlight their names on the GEM slide perhaps.<o:p></o:p></span></div>
