UHV Chamber
A special UHV sample chamber is installed below HE-4-II, and the chamber contains the following parts:

1.   Indium sealed UHV compatible stainless steel can.  This is an electro-polished stainless steel camber and it is bolted onto the bottom of HE-4-II with indium seal.  0.062" diameter indium wires should be used for the seal.  The vacuum can provides UHV space for the He-3 pots and etc.  Copper plates are installed around the outer surface as well as the bottom of the UHV can in order to keep it near 4.2 K during the operation.

2.   UHV tail - This is a 3.0" diameter electro-polished stainless steel tube with a 4.65" rotatable split conflat flange installed at the bottom.  The UHV tail passes the magnet bore and connects the UHV can with the UHV manifold located at the bottom of the UHV space.  Copper coil-foil is attached to the UHV tail with high-temperature stycast 2762 epoxy, in order to keep it near 4.2 K during the operation.

3.   UHV manifold - A special electro-polished stainless steel UHV manifold is installed at the bottom of the UHV tail.  Copper braids are installed as thermal links between the helium reservoir HE-4-I and the UHV manifold in order to keep it near 4.2 K during the operation.

4.   UHV compatible wires for the user - 18 x 0.005" UHV compatible manganin wires will be installed for the user, and all wires are thermally anchored at 4 K and 1.5 K, then terminate near the sample area.
