Suresh bought a new scatterless pinhole to act as a guard for 8-ID-I.

See text below for details. Att. 1 is the pinhole holder.

Jiang, Zhang Chu, Miaoqi is there any interest in scatterless-pinholes (not sure how scatter less they are, these are
from incoatec that are better than the ones we use, laser drilled and edges cleaned). I had talked to those people a while
back and he reached out now to close the case. While their apertures are bigger (100+ um), he said they offer 20-1000 um
Ta pinholes, 20 could end up a bit larger is my guess.

Hi,
I have been communicating with Andreas, seems like he is away. Could you
please modify the attached quote and replace the one there with the 55 um
that is in stock, we have decided to get that as we want to try sooner.
Thanks.
Suresh

Hi Suresh,
we still have one on stock. Offical optically measured diameter 51 µm.
Depending on the energy of the x-rays it coulld appear a little bit larger
in your experiment. Is this okay?
I will send you the official offer later today.
Best regards
Jörg

Hi Suresh,
The side that has Incoatec laser marked faces to the sample.
I hope I could help you.
Best regards,
Andreas

Hi Suresh,
No problem. I try to help you.
You can see the pinhole in the holder. The side that you can see in the
holder is flat/polish. The cone side of the pinhole you can not see
because this side faces to the holder, this side is bonded to the holder.
The cone side of the holder faces to the sample.
Best regards,
Andreas
