<div class="moz-cite-prefix">HI, <br>
<br>
I attached an Excel file from Steve Christo to this message. It
contains <br>
a list of the radiators that Hall B had. The cells are highlighted
with color, <br>
and the explanation for the color is at the bottom of the
spreadsheets. <br>
Some of the foils that are marked "we have" (we is Hall B) may not
be available now. <br>
We should have a look at this list and pick what we would like for
Hall D amorphous <br>
radiator, and then Steve will check the availability of those
foils for us. <br>
<br>
I think we could use 1.7e-05--Aluminum, 3.3e-04--Gold,
1.6e-03--Platinum. <br>
3.3e-04--Gold will probably match the coherent peak intensity from
30um diamond <br>
better than 1.0e-04--Gold. <br>
<br>
Stepan from Hall B told me that they abandoned 10^-5 gold foil in
favor of 10^-5<br>
aluminum foil because having a micrometer or thinner foil in the
target <br>
holder was painful because of high probability of damaging it in
the vacuum and <br>
the difficulty of handling it. <br>
