POLARIZED TARGETS (Chris)

• Discussion about needed upgrades, e.g. pumps and SC magnet

• Key for large apertures is shifting coils and minimizing material around coils

• three different scenarios discussed

• Changing from longitudinal to transverse configuration estimated on order few weeks

• rotation itself is quite fast - can be on order minutes in ideal case

• Action items/questions about Oxford design:

• Get drawing of magnet
• Get quote of magnetic field - if went below 4T not so good
• Probe safety margins and stresses etc. with company

• General note: split pair magnets with large acceptance always a challenge - strange forces, clamping very important

• New idea to address local depolarization: fix beam and raster target - target rotation looks very promising, test results shown

CONCEPT PAPER (Bogdan)

PATH FORWARD

• NIM paper
