Dear Evaristo,<br>
<br>
quick question: what does "double gate window" mean? Does this
affect the APV25 sample frequency (20 MHz vs 40 MHz?) or the number
of samples taken or something else?<br>
<br>
Regards,<br>
Ole<br>

<pre wrap="">Dear All,
find new mc/digitization GEM productions at:

a new digitization with a double "gate window" (875 ns instead of 475
ns) for the background, according to a request of Bogdan.
and

Same configuration of g17 production except:
- the magnetic dipole field is switched on at 2 T (integrated field at
2.5 Tm);
- the particles hits the tracker along a thin vertical band (y) instead
of a small spot around (0,0); in this way particles at different y
correspond to different bending and therefore different impact angle on
the GEM.
The electrons and gammas background are from production g17 (with 0 T
field).
