endcap signal feedthrough installation tests at CERN
December 2001

The endcap signal feedthrough have started to arrive in CERN in October 2001. Here are a few pictures of the installation tests performed at CERN in December 2001, using Aboud Fallou's (Orsay) insertion jig and endcap cryostat mockup, with a mockup endcap feedthrough.
