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.
