<p>Hey Marc,</p>
<p>Please find attached the information for the mods to the Bonus gas system so it can be used for ALERT.</p>
<p>Let me know when you can meet to discuss the details.</p>
<p>Thanks,</p>

<p>Hi Brian,</p>
<p><br>
</p>
<p>The ALERT group will set up their detector in the EEL as early as February, they did not seem to have a firm date.</p>
<p><br>
</p>
<p>Most of the Bonus gas system and controls will be reused. The changes are to control the pressure in the detector using the mixed gas. We will add a small buffer tank after the detector with a PT and a TT, and a control valve after the tank to control
the pressure at 1050 mbar, based on the PT. In order to provide a pressure differential across the valve, we will add a surge tank with a PT, control valve, and pump to maintain the surge tank at 800-900 mbar.<br>
</p>
<p><br>
</p>
<p>I will work on an updated P&ID for ALERT.</p>
<p><br>
</p>
<p>Thanks,</p>
<p>Bob</p>
