Performances of the lure rowland circle monochromator using gas phase photoelectron spectroscopy up to a photon energy of 280 eV

Abstract

The performance of the LURE Rowland circle grazing incidence monochromator has been determined up to a photon energy of 280 eV using gas phase photoelectron spectrometry with the PAX method. Suitable converters such as He 1s, Ne 2p, Ar 2p and Ar 3p have been used to study the resolution, the intensity, the contribution of higher orders and the level of stray light. The results obtained with various sorts of gratings (blazed and holographic, 600 lines/mm to 2400 lines/mm, replica and original gratings) are presented. The superiority of the holographic Jobin-Yvon gratings in the high energy region is demonstrated.
