A robust floating nanoammeter
B. E. Sauer, D. M. Kara, J. J. Hudson +2
A circuit capable of measuring nanoampere currents while floating at voltages up to at least 25kV is described. The circuit relays its output to ground potential via an optical fib…
Lifetime of the A(v'=0) state and Franck-Condon factor of the A-X(0-0) transition of CaF measured by the saturation of laser-induced fluorescence
T. E. Wall, J. F. Kanem, J. J. Hudson +5
We describe a method for determining the radiative decay properties of a molecule by studying the saturation of laser-induced fluorescence and the associated power broadening of sp…
Nonlinear dynamics in an alternating gradient guide for neutral particles
M. R. Tarbutt, E. A. Hinds
Neutral particles can be guided and focussed using electric field gradients that focus in one transverse direction and defocus in the other, alternating between the two directions.…
Preparation and manipulation of molecules for fundamental physics tests
M. R. Tarbutt, J. J. Hudson, B. E. Sauer +1
This paper is a chapter from an upcoming book on cold molecule physics. In it we describe techniques for the preparation and manipulation of cold molecules. We further describe tec…
Pulsed beams as field probes for precision measurement
J. J. Hudson, H. T. Ashworth, D. M. Kara +3
We describe a technique for mapping the spatial variation of static electric, static magnetic, and rf magnetic fields using a pulsed atomic or molecular beam. The method is demonst…
A supersonic beam of cold lithium hydride molecules
S. K. Tokunaga, J. O. Stack, J. J. Hudson +3
We have developed a source of cold LiH molecules for Stark deceleration and trapping experiments. Lithium metal is ablated from a solid target into a supersonically expanding carri…
