Contract - Photoemission spectroscopy and microscopy beamline

Consortium CELLS
Barcelona, Spain
Deadline: 2014/03/28

Description

ALBA is the Spanish 3-GeV synchrotron radiation facility operated by the Consortium CELLS, which is equally funded by the Spanish Government (Ministerio de Economía y Competividad) and the Catalan Government (Generalitat de Catalunya, Departament d'Economia i Coneixement). Out of the seven operating phase I beamlines, BL24-CIRCE is a variable polarization, soft X-ray beamline dedicated to photoelectron spectroscopy and microscopy. 
The beamline has two branches equipped respectively with endstations for PhotoElectron Emission Microscopy (PEEM) and Near Ambient Pressure Photoemision spectroscopy (NAPP) . 
The Near-Ambient Pressure Photoemission (NAPP) endstation is an Ultra High Vacuum (UHV) setup equipped with a hemispherical electron energy analyzer for X-ray Photoelectron Spectroscopy (Phoibos NAP150 from SPECS) that can operate at a sample pressure range from UHV up to 25 mbar thanks to a differential pumping system which ensures a pressure difference of 109 between detector and sample [http://rsi.aip.org/resource/1/rsinak/v73/i11/p3872_s1]. 
Therefore the usual characterization capabilities of XPS are extended to the study of gas-solid and gas-liquid interphases, with applications to in-situ characterization of heterogeneous catalysts, corrosion processes, wetting, fuel cells, photovoltaics, etc.
The beamline is open to worldwide scientific community since 2012. The scientific staff of the beamline is responsible to give support to academic and industrial users and is also in charge of the maintainance and continuous upgrade of the beamline.
The beamline scientists are encouraged to carry on a scientific programme using the capabilities of the beamline. 
In the forecoming years the in-house research program for the NAPP will include the following topics:
- Supramolecular self-assembly of organic molecules in near ambient conditions.
- Photoemission and X-ray Absorption of organic molecules in solutions, including the implementation of a microjet generator for the NAPP endstation.
- Tailoring catalytic properties of metallic nanoparticles under reaction conditions.

The successful candidate will:
* Provide Local Contact support in experiments to scientific groups using the CIRCE beamline, mostly on the NAPP endstation.
* Develop an in-house scientific program focused on the NAPP end station.
* Maintain the beamline together with the rest of the beamline team.
* Participate in projects to continuously improve and upgrade the beamline, notably regarding the NAPP end-station setup.

Requirements

The candidate should have a PhD degree in Physics, Chemistry, Material Sciences or related disciplines. He/she 
should also have sound experience in X-ray Photoemission Spectroscopy, soft X-ray absorption spectroscopy and UHV 
instrumentation.
Other assets are:
* Experience in Near Ambient Pressure XPS.
* Experience working at synchrotron radiation facilities.
* Good interpersonal skills, adaptability to a multidisciplinary environment, sense of responsibility and 
  capabilities to work in a group, as well as to work independently for some periods of time.
* The working language at ALBA is English. A good level of English both written and spoken is required.

More information and applications

Due to a Spanish current regulation, the initial contract will be for three years, including a test period of six 
months. This position could be permanent as soon as it becomes possible.
Yearly gross salary close to 36,000 Euros, according to qualification and experience.
