Furthermore, an electrical patch field enables the connection of sensitive equipment with short signal paths to the experimental test stands.  Two direct feedthroughs between TT61 and TNC allow the connection of auxiliary equipment like gas tubes, UHV hoses or optical fibers. TJ7 and TT61 have CERN network-enabled ethernet ports to facilitate remote control....&quot;</title>
