We plan to evaporate in a magnetic trap, then an optical dipole trap. It will be an all-potassium evaporation, without sympathetic cooling, unlike for the chip experiment.

Magnetic evaporation

QT Coils
Magnetic evaporation takes place in a quadrupole trap. The coils used to make this trap were wound by Oswald GmbH.

Anodizing the mounts
Thermistor Calibration

RF source
Oscillating magnetic field in the lattice chamber is generated via a transmitter coil mounted on the imaging window. The coil is driven by the Microwave Source, and can create fields with frequencies from 1160MHz to 1300MHz.

Optical Evaporation
