I have ordered the silicon heaters and have been in contact with the buyer, so that part has started. I expect delivery in the first week of October.<br>

Amrit has advised that we focus on the controls, so with that in mind we will not commit DSG resources to assembling the 6 supermodule test stand.

<div class="PlainText">Hi Marc,<br>
<br>
Today I discussed your proposal with Bogdan,<br>
and we confirm the order of the heater.<br>
Please order 12 heater and test with 6 SM.<br>
You also need to install an aluminum bars<br>
on the sides of the super modules.<br>
You need to control the temperature in front<br>
and behind the lead glass.<br>
If you need help creating a prototype, we can<br>
arrange a meeting and discuss?<br>
<br>
Thank you,<br>
Albert<br>
