The Longest Ladders of all The Gossamer Tracker
Q Can the entire half-length be read out as a
single element?
Agilent 0.5 mm CMOS process (qualified by GLAST)
Min-i for 300mm Si is about 24,000 electrons

Potential Advantages of the Gossamer Tracker
Such a tracker may prove mechanically simpler,
and offers the greatest possibility of competing
with gaseous tracking at low p?.
We are awaiting the return of a prototype
front-end chip, and designing the digital
data-handling architecture.
