[Dsg-rtpc] [EXTERNAL] Re: RTPC Cable Length

[mhattawy@odu.edu]

Hello Brian,
    No one has this measurement. If you do have an access to Hall-B, you
need to measure the distance between the A shape iron frame in the back of
the rack, carrying BAND, and the end of the CVT.

Best regards,
Mohammad.
