[Halld-tracking-hw] Straw tubes

[Tim Whitlatch]

Hi All,

I spoke with Patrick Hester from Lamina this morning. He has settled the 
material with Sheldahl and will be placing an order today. The material 
is 1 mil Mylar with 1000A aluminum. The QA step at Sheldahl is to 
measure resistance. It must be <1ohm/square. The normal measurement is 
usually 0.4 ohm/square according to Sheldahl. This would ensure the 
material has at least the same amount of aluminum as the previous 
straws. The material will take about 4 weeks to obtain and there should 
be a 2-3 week turnaround at Lamina. If all goes well, we should have the 
remaining straws within 2 months.

Cheers,

       Tim
