T0 Changes
¥Observed poor T0 vertex resolution (> 15 cm) as
soon as silicon vertex information was available and that OR signals were late
compared to PR03.
¥Problem due incorrect orientation of cable between
discriminator and TEQ.
¥Change in cabling moved Ors forward by 75 ns.
¥Discovered problem with TDC 17 (or slot 17).
¥Moved ORs to TDC 8. Resolution improved to 8 cm.
