[PEPPo] PEPPo layouts for comment

[Yujong Kim]

Dear Dr. Grames,

I looked into them.

They are very useful information for our simulations.

Just one strange thing, transverse positions of the first scraper (or slit)
are different in two layouts (peppolayout.pdf and specchamber.pdf). Its
position in peppolayout.pdf is T = 5.50
but its position in specchamber.pdf is 5.88. Please would you check which
one is right one?

If one layout has wrong information, we have to update it.

I guess that its unit is inch. Is my guess right?
If it is inch, please would you add its unit in layouts?

If we have a table, which gives information of length or thickness of all
components, it will also be very helpful.

I also want to know the diameter of screen in the spectrometer. Normally,
the beamsize in the spectrometer is wide due to the horizontal dispersion.
Therefore, we have to have a wide screen there.

Sincerely yours,

Yujong Kim
