UHV-Compatible Electrostatically-Driven Tuning Fork Chopper

reportActive / Technical Report | Accession Number: ADA256943 | Open PDF

Abstract:

We have developed an electrostatically driven tuning fork chopper which is compatible with an ultrahigh vacuum UHV environment. Constructed with a commercially available tuning fork using stainless steel and alumina parts, the chopper is capable of operating while exposed to high temperature samples and corrosive gases. Operation in a UHV environment while modulating both optical and molecular beams is demonstrated. Tuning fork chopper, Ultrahigh vacuum, Molecular beams.
