All neg feed-throughs have now been fully installed, with ground tags 
and power wires crimped and attached to the correct pins. Feed-throughs 
are installed as seen in Image 
1 of zip file, with mark at the top of the feed-through. The pin 
assignment is seen in Image 2. The pins are assigned letters A to F, 
with F the top pin and C the bottom 
pin as installed(refer to images 1+2). The ground is pin c, with the 
two power wires connected to the bottom pins either side of the ground 
(pins b and d). Connections of 
wires from the negs to the feed-through is seen in image 3. Feed-
throughs have been electrically checked. The ground pin is checked 
against the chamber giving 
approx 0.5 ohms and the power pins are checked together giving 5-10 
ohms. Each of the power pins are open circuit with respect to the 
ground. A 
thermocouple has been attached under the bolt of one of the neg pumps 
(image 4).

Pirani gauge and hot cathode gauge have been installed on the chamber 
(images 5,6,7,8) on the section furthest from the turbos.

Upper valve, turbo and supports have all now been installed (images 
9,10,11). Images 12,13 are of the internal of the turbo and turbo 
ports. The lower valve supports 
produced by the Daresbury group (image 14) are also now attached. These 
supports were required as the lower valve sits higher than anticipated 
due to shorter right-angled 
flanges.

Chamber is now ready to close and leak test!
