BL8-1 is equipped with a post-monochromator beam-splitting mirror to allow for two sample chamber locations. BL8-1a accommodates roll-on user chambers. BL8-1b is under modification to provide energy range from 2eV to 10eV. The mirror cooling system was upgraded in FY04 and the BL8-1 stations are SPEAR3 500 mA compatible. Stations 8-1a and 8-1b cannot be used simultaneously.

| Data Acquisition and Analysis | Data Aquisition: Photoemission spectra are collected by electron energy analyzers installed on UHV chambers. Software Super (installed on the beam line computer) can be used to control standard PHI CMA ananlyzers. Data Analysis: Core level photoemission peak fitting can be performed using any XPS peak fitting procedures.
