Reconstruction
Efficiency, Wheel -1, MB2.
Notes:
Sector 3. Poor efficiency in Phi2: average layer efficiency ~94%
This is due to last ~20 cells: see below the efficiency wire by wire
and
here
the efficiency as a function
of drift distance for a group of faulty cells.
Probably bad gas conditions
during data taking.
(In fact much better behaviour at
sector commissioning
may 2007)
Sector 9. Poor efficiency in sl theta: average layer efficiency ~90%
Efficiency uniform within the chamber (see below the efficiency wire by wire)
and here
the efficiency as a function
of drift distance.
Poor efficiency also in Phi2: average layer efficiency ~96%
This is due to first ~20 cells: see below the efficiency wire by wire
and here
the efficiency as a function
of drift distance for a group of faulty cells.
Bad gas conditions during data taking?
