Outgassing rate comparison of seven geometrically similar vacuum chambers of different materials and heat treatments
James A. Fedchak, Julia K. Scherschligt, Sefer Avdiaj +5
We have measured the water and hydrogen outgassing rates of seven vacuum chambers of identical geometry but constructed of different materials and heat treatments. Chambers of five…
A Bitter-type electromagnet for complex atomic trapping and manipulation
J. L. Siegel, D. S. Barker, J. Fedchak +2
We create a pair of symmetric Bitter-type electromagnet assemblies capable of producing multiple field configurations including uniform magnetic fields, spherical quadruple traps,…
A radiofrequency voltage-controlled current source for quantum spin manipulation
D. S. Barker, A. Restelli, J. A. Fedchak +2
We present a design for a wide-bandwidth, voltage-controlled current source that is easily integrated with radiofrequency magnetic field coils. Our design uses current feedback to…
