Grounding:
Each MWC card has a copper ground strap connected to a sector mounting
bold in order to improve its grounding and control noise.
MWC cards:
The 24x15 (or 16) MWC cards mounted on the TPC are nominally
interchangeable. They are powered through the readout boards.
Response:
The response of the MWC cards is slightly faster than for their
FEE-card relatives: the FWHM signal out of the shaper/amplifier is
about 150 ns, as opposed to 180 ns for the FEE cards.
