High performance temperature controlled UHV sample holder.

A requirement of many surface science studies is the capability to alter a sample temperature in a controlled mode. Sample preparation procedures such as heating or cooling ramps, high temperature spikes, fast annealing, or simply maintaining a sample at a very high, or very low, temperature are common. To address these issues, we describe the design and the construction of a multipurpose sample holder. Key points of this design are operation in an extended temperature range from liquid nitrogen (LN2) temperature to ∼1300K, temperature control during heating and cooling, low thermal inertia with rates up to 50Ks−1 (heating) and −20Ks−1 (cooling), and small heated volume to minimize background problems in thermal desorption spectroscopy (TDS) spectra. With this design the sample can be flash heated from LN2 temperature to 1300K and cooled down again in less than 100s. This sample holder was mounted and tested in a multitechnique apparatus and adds a large number of sample preparation procedures as well as ...
