<p class="MsoNormal">Hi Annalisa, <o:p></o:p></p>
<p class="MsoNormal">Thanks for sharing these slides even though it appears six weeks later (manager of the mailing list’s fault
<span style="font-family:"Segoe UI Emoji",sans-serif">😊</span>) <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a couple of questions: <o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Your green and red dots seems to indicate that you tested 2 capacitive sharing prototypes. Is that correct and if so, were both prototypes identical?<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">With 1.2 mm pitch capaSh readout, why are the resolution so bad at low HV i.e. higher than 500 um at 520V? Even in the worst case scenario where of single strip event, you should expect
a resolution better than pitch / sqrt(12) <span style="font-family:Wingdings">è</span> 1200 um / 3.4 = 346 um
<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Actually you have a strip multiplicity higher than 2.5 even for low HV so your spatial resolution should be even way better than that 340 um<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">The same comment for the blue where for 780 um pitch, you should get at the very worst 225 um resolution for single strip not 300 um. It looks to me that something is off in the analysis
of the spatial resolution. <o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Your plots are comparing TOP prototypes with 780 um pitch with capaSh with 1200 um pitch, I think it is an unfair competition for caspSh
<span style="font-family:"Segoe UI Emoji",sans-serif">😊</span>!<o:p></o:p></li></ul>
<p class="MsoNormal">Anyway, very interesting results, thanks, <o:p></o:p></p>
