Two-dimensional imaging of neutral alkali atom samples using surface ionization
We describe the design and characterization of a high resolution, high efficiency detector for two-dimensional imaging of neutral atoms. Incident atoms are surface-ionized by a tungsten-coated hot ribbon and the resulting ions are accelerated into a microchannel plate detector with a phosphor screen...

| description | We describe the design and characterization of a high resolution, high efficiency detector for two-dimensional imaging of neutral atoms. Incident atoms are surface-ionized by a tungsten-coated hot ribbon and the resulting ions are accelerated into a microchannel plate detector with a phosphor screen output. With this design we can detect individual alkali and other low ionization potential atoms and molecules with a spatial resolution of
∼20 μ
m
.
We find backgrounds on the order of 30 Hz over an active detection region of
20
mm
2
,
a time response of
⩽1/30
s
,
and a detection efficiency of
∼50%.
This detector can be used to image cold as well as thermal atomic or molecular beams. |
