Re: Additional data
Hi Fernando,

I added three raw fADC spectra on the wiki page with all the Fe-55
measurements.

I can describe it because it is simple. If it does not suffice i can make
a drawing.
A collimated (0.5~mm) Fe-55 source is placed close to the straw. The
signal coming from the straw is preamplified and shaped. After the shaper
the signal is split in two, using a passive LEMO splitter. One part goes
to a discriminator (it is not a CFD) afterwards it is delayed a bit and
triggers the fADC. The other part goes directly to an fADC input.

I do not know if i understand what you want here. I have some energy
spectra = integrated signal over time. I do not think if one can call it
energy spectra because the amplifier converts charge into amplitude.
Anyway I will put 3 of these spectra on the wiki (3 different HV).
See you at 4pm.
Cheers,
