A beamline for high-resolution angle-resolved photoelectron spectroscopy (ARPES) has been built at Diamond light Source in the United Kingdom.
The full extent of the project will consist of two instruments, nano-ARPES that is currently under commissioning, and high-resolution HR-ARPES that started full operation in January 2014.In this seminar I will describe the implementation of HR-ARPES and its extended sample preparation facilities and gives a few examples of research that has been conducted.

As a particularly interesting case study I will present data from 　quasi-one-dimensional Tl₂Mo₆Se₆ where a survey of momentums spaces reveals an indeed highly one-dimensional Fermi surface and peculiar reduction of intensity near E_F that will be discussed in the context of Tomonaga-Luttinger liquid theory.
