Just verified that everything from the order is in the box we have in the Lehigh office. Only irregularity was we got an extra set of both orders of black oxide screws.

Best,

Micah

The attached PDF was everything in the last McMaster order that was all for sEPD.  I am %99 sure this was for the support structures (larger hardware) and the sectors (smaller hardware).

The box of all this was given to the Lehigh team a few weeks ago and you should have it all.

Let me know if

1. There is anything missing from McMaster order
2. Anything we just forgot to order that we need for the sectors.

Hi Russ and everyone,

After yesterday's meeting and our meeting this morning, we have a few questions to set our schedule's:

Handles on the petals (I attach Rich's picture): We will need to modify the petals for this, is that something that will be done here?  What is the time scale.  We will assemble 1 of the strongbacks with sectors asap to ensure everything works, but would not want to do this with the other's prior to the modification.

--> Rich is working to get the drawing to us in the next day or two.  Then we can drill and tap the petals next week.  We need to order the handles and get them in because the screw that clamps the handles to the strongback are screwed in from the tile side.

sEPD "bike rack": Once we assemble the sectors into the petals, we will need to be able to put them some place.  It would be good to know the time scale for approval, order and arrival for this.

--> Rich is working on finalizing this.  I will ask him to send the preliminary BOM so we can order the 80-20 and other hardware.

SiPM Box installation: We probably should have a dedicated discussion on this, some additional hardware will be needed.  (For instance, the standoffs.)

--> I am trying to figure this out too.  Will try to have some answers by Friday

McMaster Orders: Micah, JaeBeom, Tristan are doing inventory - it would be good to have the list of McMaster parts already ordered to check off what we have.

--> OK, I will send you what I have

Rosi
