<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>
