Needle cards:
-------------
A needle card is developed for the ATLAS project. Due to some
bugs the card needs a second iteration. This gives us the
possibility to propose some changes/enhancements so that the
card can be used for our projects.
Suggestions:
* connect every power needle to the corresponding
power ring
* add power connectors (instead of using the Samtec-
plug for the power connections)
CMOS6SF user meeting:
---------------------
* U. Trunk has made up a list of future submissions
for both projects.
* U. Trunk shall pick up information about Monte Carlo
simulations with the cmos6sf design kit.
OTIS:
-----
* The DACs implemented on OTIS1.0 can not deliver enough current.
DACs on OTIS1.1 will be buffered.
The currents needed are:
Threshold ASDq: I [uA]
low 200
high 600
Threshold [V] ASDblr: I [uA]
0 0.8
0.12 1.0
0.3 0.15
0.35 1.58 this is about the standard level
0.4 1.7
0.45 1.83
0.5 1.94
1.0 3.14
1.5 4.48
2.0 5.72
2.5 6.9
3.0 8.2
3.3 9.2
3.5 18.5
3.6 53
3.75 127
4.0 277
4.5 600
Ciao,
