<p>Hi Zahra,</p>
<p>Regarding coincidences with a system made of two heads, this
command could solve your problem <br>
</p>
<p>/gate/digitizer/Coincidences/minSectorDifference 1</p>
<p><br>
</p>
<p>For the configuration you can try these options <br>
</p>
<p>/gate/head/repeaters/insert ring<br>
/gate/head/ring/setFirstAngle <br>
/gate/head/ring/setAngularSpan <br>
/gate/head/ring/setRepeatNumber <br>
</p>
<p>You can find more details in

<p>I hope it helps,</p>
<p>Ane </p>
