Experimental Station 8-2

BL8-2 can be used to probe a wide range of core levels using photoemission and x-ray absorption spectroscopy. At BL 8-2, two end-stations have been composed for the general user program. The first end-station is a high throughput setup for soft x-ray spectroscopy measurement – Upgrades in progress include a fixed position multipurpose chamber with a load lock system for high throughput sample loading, capable of probing a wide range of materials with absorption and photoemission techniques. The second end-station is designed for controlling a temperature (4 - 350 K) and pressure (10-4 ~ 10-11 Torr) during XAS measurement.
