WK's ASDQ Page

This page includes information on the Penn's development of the ASDQ daughter board for the COT (Central Outer Tracker) for the upgrade run of CDF.

In the summer of 1999 we were in full production and testing of the COT ASDQ daughter boards.

We also did a thermal study of COT ASDQ daughter boards in 1998. To see the results go to ASDQ thermal studies page
