Outlook for beyond p+p.
¥We will
need to address the T0 cable issue.
¥Options to
considered:
¥Use
BNC (required to go from ECL to NIM to the CH and then via a discriminator and
a NIM to ECL converter to the TDC).
¥Change
the relative alignment of cables (in order to ensure that the straight sections
of the cables do not overlap).
¥Replacing
T0 cables with shielded cables.
¥Moving
FB into the tunnel.
¥The cross talk between
channels within a cable is easily visible on a scope, but it only becomes
serious when the cable is unrolled.
Note: in most applications where the twisted pair cables were used to
delay ECL channels, the cables are left in their original package and only the
two ends are pulled out to be connected to the delay box.
