<div dir="ltr">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><br>

<div>I am updating the runlist on wiki. How long do you think each run should take? Would one hour be enough for each 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>
<div>Given the high rates , it might be useful to take a run with the sieve in the SHMS.</div>
