possible pair spectrometer magnets (fwd)
Dear tagger
While at BNL I went looking for possible magnets for the pair
spectrometer. I found several which look like good candidates.
The 20x42 looks to be very interesting. It is a C-Magnet with the
following characteristics:
pole width 508mm
pole gap 203mm
pole length 1067mm
Max field 1.85T
The gap is too large but it would be easy to add plates to the poles to
reduce this. A C-Magnet has the advantage that on one side of the magnet
we can measure very low momentum particles. Installing the vacuum chamber
can also be done without taking the magnet apart.
The 24-8-72 is an H-magnet with a field clamp and relatively wide poles.
pole width 609mm
pole gap 203mm
pole length 1829mm
Max field 1.85T
To reduce the gap here you would need to add tapered plates. This could
be done but requires a simulation.
The 18D36 is also an H-magnet. It has a somewhat narrower pole and is more
compact. (18" wide pole and 36 inches long)
They may also have power supplies for the magnets above. We would need to
install new controls in any supply we got.
I feel that the 20x42 is a rather good match to our needs.
Please let me know what you think!
