25-Foot Bubble Chamber. The first Brookhaven-NAL coordination meeting on the chamber was held at Brookhaven. It was decided as a design basis to fix the magnetic field at 40 kG, with a coil separation of 5 feet

Model Superconducting Bending Magnet. The winding of the coil has been completed. The con has been tested to 950 A, the current required for 20 kG in the final configuration

Superconducting Solenoid. The twisted-strand coil has been rewound with additional insulation, which removed the turn-to-turn shorts described here last month. The coil has been tested

the critical current is independent of the charge rate over the range tested. The fastest charging rate -13NAL-24 0090.01 gave 10 kG in 0.3 sec, limited by the power supply. A new coil, with better insulation has been wound and is being tested
