</div>
<div dir="ltr">We are currently integrating the ALERT DC gas controls used in the EEL to the cRIO controller in the hall. We have read back from the sensors. Right now we are working on the solenoid control for ALERT and BoNuS. Then we will start pressure control

<div>Hi Marc,<br>
</div>
<div><br>
</div>
<div> We will have an ALERT meeting today where I'd like to report on your progress with the gas system for ALERT.<br>
</div>
<div> Can you give me an update of what you've been able to complete this week, please?<br>
</div>
<div> Sometimes Bob attend the meeting too, so if you've already agreed that Bob will give the update, don't bother sending me an email.<br>

<div dir="ltr">The panel was moved to hall b earlier this week. DSG is working with hall b engineering and mechanical to connect the instrumentation and get the system running. </div>

<div>Hello,<br>
</div>
<div><br>
</div>
<div> As you probably know the panel is now inside the Hall and ready to be set.<br>
</div>
<div><br>
</div>
<div> The temporary setup installed by Bob was very helpful but of course the lack of controls forces us to check that everything is fine everyday.<br>
</div>
<div> Even when I was on site, I did not do it properly: I did see a bottle was empty and then didn't see that the flow meter was closed.<br>
</div>
<div> It is anyway not possible to know immediately when a bottle is empty. With the new system this kind of problem will be avoided.<br>
</div>
<div> <br>
</div>
<div> Hence I'm going to wait that the gas system is accessible via EPICS. So please, whevener you have time, can you work on it?</div>
<div><br>
</div>
<div> Bob, right now everything is opened as I was still running HV tests tonight. HV are now off.<br>
</div>
<div> Can you close the flow meter please? And then fill the Hall pipes with N2 at twice the atmospheric pressure. That will keep water away and speed up the restart process.<br>
</div>
<div><br>
</div>
<div>See you when the beam will be in Hall B,<br>
</div>
