PHOIBOS 150 HV NAP 1D-DLD

State of the art hemispherical energy analyzer with 1D-DLD HV detector for photoelectron spectroscopy measurements (XPS and UPS) in the pressure regime from UHV to near ambient pressure (NAP). With this analyzer NAP-HAXPES measurements up to 7 keV can be performed.

The PHOIBOS 150 NAP Analyzer is a true 180° hemispherical energy analyzer with 150 mm mean radius. It consists of a differentially pumped electrostatic pre-lens, with a three-stage differentially pumped PHOIBOS 150 analyzer. Thus, the design concept provides four separate pressure stages separated by apertures. The first pumping stage (pre-lens) is separated from the analytic chamber by a nozzle with a customizable opening at the tip with diameters between 0.3 mm and 1 mm. By using a turbopump on the pre-lens stage, a pressure difference of four orders of magnitude (compared to the analysis chamber) can be achieved.The first and second stages are separated by an aperture. An in-lens gate valve allows a high-vacuum seal between of the PHOIBOS 150 Analyzer and NAP pre-lens and enables venting of the analysis chamber and pre-lens without venting the energy analyzer.

For Imaging NAP-XPS the pre-lens can be equipped with the SPECS NAP-XPS Imaging Lens Module that supports two different operation modes, one optimized for lateral resolution and one for transmission. In the lateral resolving mode the acceptance angle can be freely adjusted between +/- 3° to +/- 8° giving an ultimate lateral resolution of better than 10 µm with an acceptance area of 0.6 mm in diameter and better than 20 µm for HAXPES regime.
