Suranaree University of Technology has recently been accepted as full member of the ALICE collaboration. Wanchaloem Poonsawat, a PhD student from SUT has recently moved to CERN to work closely with his supervisor, Dr Chinorat Kobdaj on the ITS Upgrade Project



A.M. What is your previous background?

I completed my M.Sc. in high energy physics in 2010 and since then I am working in HEP and particularly in the study of hadron physics.

I am personally interested in the (re)construction of the dynamical equation that describes the Kaon-nucleon interactions. Specifically I am interested in working out (calculating) the potentials which could reproduce the low energy scattering data, kaonic hydrogen atom data, and the transition amplitudes predicted by other theoretical approaches.

Otherwise, I have the permanent position of a lecturer in the University that gave me a chance to study for a Ph.D. in a topic related to ALICE.

A.M How did you decide to work in the ITS Upgrade?

The theory in Physics must be proved by a credible experiment. The upgrade of the ALICE ITS will give us more data to study and enable us to reach the new physical regimes. Hopefully, the upgraded ITS will contribute significantly to our understanding about the formation of the hadrons and other particles –which combine and form the ordinary matter that we see around us- out of the Quark Gluon Plasma.

A.M. Were you familiar with the physics of ALICE?

As I already mentioned I was familiar with HEP since my first university degree. The study of QCD, QGP, Gauge field theory, and the scattering problem were the main areas of study that I was interested in. On the other hand the tracking method and the simulation of collisions are totally new fields which I am now studying in order to advance my research with ALICE.

A.M. What were your feelings when you first arrived compared to what you were expecting?

I arrived at CERN around the beginning of October and I am staying until the beginning of December. This is my first time in Europe and being at CERN is a great experience from which I learnt a lot. I don’t have much free time since I am trying to do my best during the period that I am staying here and explore all the different things that are taking place around. From very early in the morning I start working at CERN as I am trying to catch up with the other members of the collaboration in their research. Moreover, I closely work with my supervisor Dr. Chinorat Kobdaj.

I am really looking forward taking a few days off once I get back to Thailand.



The inner stave model of the Upgraded ITS design


A.M. Your future plans? What is your aim during the period that you will be spending here?

Complete my small part of ITS Upgrading by reconstructing the new inner stave model and re-correct the overlapping of ITS design from the simulation results. I hope that one day I could also work on data analysis from the upgraded ITS and that the collaboration of my institute (Suranaree Institute of Technology) with ALICE will give new interesting results.
