Orientation of beam-solenoid-jet
facts:
 | convention: A positive angle in vertical plane indicates an orientation
up (=start is lower than end in beam direction) |
| The US NuFact design assumes a horizontal orientation of the magnetic
axis, the proton beam is tilted by -67 mrad, and the mercury jet by -100
mrad with respect to the proton beam, both heading the same direction. |
TT2A:
| The proton beam is horizontal. |
first possibility (Figure see below):
| assume: Hg-jet is tilted down |
| magnetic axis is tilted up. |
| This does not work, as the magnetic bore is tilted up, and the spilled
mercury is flwoing back through the bore. FINISH |
second possibility (Figure see below):
| flipping aver the vertical axis does not solve the problem of previous
considerations and has to be dropped as well. |
third possibility (Figure see below):
| flipping possibility 1 over the horizontal axis provides a solution for
the mercury loop, spilling it from the high end of the magnet bore to the
low one. |
| The low end of the bore collecting the mercury should also be the side
of the reservoir. |
| The pump is located at the side of reservoir. |
| The service end of the magnet (LN2, power) is located opposite to the
mercury pump. |
| LN2 has to be drazined from the magnet opposite the service side (either
additional drain or long pipe inside cryostat). |
