<div style="">Hi Hamza,
<div><br>
</div>
<div>
<div>My two cents: It might make sense to keep the elastics together to properly commission the coincidence trigger and study the effects of proton nuclear interactions.</div>
<div><br>
</div>
<div>You can keep things efficient by starting with the highest HMS momentum, and then continuously lowering the momentum while going through the settings (going through them in reverse order from how Mark send them).</div>
<div><br>
</div>
<div>Anyway, just my two cents :-).</div>
<div><br>
</div>
<div>Cheers,</div>
<div>Sylvester</div>

Hi Mark,
<div><br>
</div>
<div>Do you want to run all elastics in the beginning of the experiment or run each elastic before running the corresponding kinematics? Since it will take some time to change the momentum settings, would it be more efficient to run each elastic just before
we run the corresponding kinematics run? </div>

<div>We should do this first to check out the coincidence timing.</div>
<div>The HMS timing will shift about 30-40 ns compared to the electrons</div>
<div>that are presently in the HMS. I talked to Brad, so he will be available </div>
<div>to adjust the coincidence trigger timing.</div>
<div>We should do one run with singles SHMS trigger and then one run with coincidence</div>
<div>trigger so that we can measure the losses due to proton nuclear interactions at</div>
<div>these momentum.</div>
<div>The rates are very high. So this should not take to long.</div>
