The contents of the interview is as below .

～ Please tell us about content of your study before entering KEK

(Sokendai at KEK) ? ） ～

（Omet）Before coming to KEK I have studied physics at the Technical University Darmstadt in Germany with a main focus on accelerator physics. My Bachelor-Thesis as well as my Master-Theses I wrote at the RF department at GSI Helmholtz Centre for Heavy Ion Research GmbH in Darmstadt. During my Bachelor-Thesis I developed and tested an analog detector for the gap voltage amplitude of RF cavities at Recycled Experimental Storage Ring RESR at the Facility for Antiproton and Ion Research FAIR. During my Master-Thesis I developed and tested a universal FPGA-based arc detector for RF cavities that fulfills the requirements for the operation at the facilities at the already existing heavy ion synchrotron SIS 18 as well as at the Facility for Antiproton and Ion Research FAIR.

（Phan） Before I enter KEK, I spent 4 years (form 2002 to 2006)for Science bachelor degree

 at University of Science, HCM city. Then I backed to my home town for teaching

 activity, one year I stay here. Then I return to University for Master degree (from

 2008 to 2010). My master thesis is to calculation Feynman one-loop four-point

 integral. In last summer (2010), I had a chance to visit KEK. I decided to come

 KEK for my PhD degree.

～ Why did you want to enter KEK ?

 How did you know KEK and what made you to applying KEK ? ～

（Omet）　About four years ago I started to learn the Japanese language in a language class at Technical University Darmstadt. In order to deepen my skills I started to meet with a Japanese tandem partner, who introduced me to some of her friends. One of those was Dr. Kei Sugita who has a position at the magnet department at GSI at the moment. I asked him, if he knew any possibility to make a PhD in Japan. He introduced me to Akira Yamamoto-sensei, who has been his supervisor during time he was making his PhD at KEK. In March 2010 I spent four weeks in Japan for holiday. During this time I visited KEK for a personal introduction to Yamamoto-sensei and he gave me a nice guided tour around the facilities and introduced me to Hitoshi Hayano-sensei as well as Susumu Kamada-sensei. All of us had a positive impression so we continued having contact. During the application to Sokendai University and the MEXT scholarship I had an interview at KEK in October 2010. During this time I was introduced to Shinichiro Michizono-sensei. Fortunately everything went well and finally I got the position at KEK. Michizono-sensei is now my supervisor.

I am very glad that I have the possibility to combine my work and studies in the field of accelerator physics, especially in the field of control systems for superconducting cavities, at one of the worldwide leading accelerator institutes with my hobby and interest of learning the Japanese language.

（Phan）Firstly, My dream is to become a science researcher. I also would like to get deeply knowledge in physics science. Therefore, That desire me to decide to learn PhD.

I visited KEK last year. I stayed here 3 months for internship program. During my working time in KEK, I realize that KEK really is one of the best institute with many expert in particle physics. That a reason I choice KEK for my PhD degree.

I discussed with my supervisor(he is my supervisor in Vietnam) that I want to come KEK for my PhD degree. At that time, He also suggest me that KEK is the best place for my PhD degree. Thus he discuss with Kurihara-sensei about my case. Finally, Kurihara-sensei suggest me to apply for MEXT scholarship. Now, My dream become true. I am a student of SOKENDAI University.

～ What research do you do now? and tell us about exciting part of the research.～

（Omet）At the moment I am learning how the cavity control systems at STF and cERL are working. This will be the basis for my future work. The exciting part of the research in this field is to build highly sophisticated cavity control systems no one has built before. Every new accelerator like for example the ILC needs custom-made control systems with very challenging requirements. Archiving this is one of my main motivations.

（the interview went smoothly）

（Phan）My topic is to calculate cross section of the process: pp–> W/Z+ 1(2) Jet by using Grace system. The exciting part of the research is first to use computer system to automatic calculate this process which can not be done by hand deal with a large of Feynman diagrams. Second, my result will be compared with experiment result at LHC to check the Standard Model.

～ What are the good points (or bad points) of KEK as research center ? ～

（Omet）KEK is a huge and worldwide leading accelerator institute with many brilliant scientist of a wide range of scientific fields. This is a perfect environment for studying and gaining a descent as well as a broad knowledge. During the five weeks of my stay here I have not encountered any bad point of KEK.

（Phan） KEK have a strongly relationship between experiment and theory physics.Therefore, the theorist can understand experiment physics well and they know the relationship between experiment physics and theoretical physics. In Vietnam, we do not have many experimentalist. Therefore, I learn particle physics but I have no change to understand experiment physics well. Coming KEK, I have chance to learn experiment and understand this relationship.

（ Dean asked the new students some questions）

（Omet）In the future I will work on digital FPGA-based control systems for superconducting cavities for cERL or STF in the scope of ILC. The exact topic has not been decided yet.

（Phan） I would like to keep my presented study at KEK in the future, develop GRACE system to calculate LHC process.

（Omet）During the one month of holiday in 2010 I traveled around Japan and visited many cities and places like Tokyo (I also visited RIKEN and had a guided tour around the accelerator facilities there), Nagano, Matsumoto, Hamamatsu, Kyoto, Nara, Hiroshima, Miyajima, Fukuoka, Beppu, Takachiho, Kumamoto, Osaka, and of course Tsukuba (refer map below). During my current stay in Japan I have also visited Yokohama, as well as Hayama for the entrance ceremony at the Sokendai University and Kamakura during the culture course. I think I had the possibility to see many faces of Japan for example in urban as well as rural regions. Everywhere the people were very kind and hospitable. In fact there was no place I did not like.

The most impressive experience I had at the Peace Memorial Museum in Hiroshima. The visit there really changed my point of view about the usage of atomic bombs.

The three most beautiful places in Japan I visited were Kyoto, Nara and Miyajima. I think sadly it is impossible to have enough time to see and enjoy every nice spot in those places, especially in Kyoto.

When people are asking me which places I would recommend to visit, I always  recommend Tokyo and Kyoto. I think by visiting those two cities one can get a very good impression about the modern as well as the traditional and cultural way of life in Japan.

Beside this all I really love Japanese food. So my overall impression of Japan is very positive.

Regarding Tsukuba my impression is dominated by two pints. Because of the short history of the city everything is very wide spread. Due to this fact one needs at least a bicycle to survive in Tsukuba. The public transportation system is not as convenient as it could be. But on the other hand it is a perfect place for study and science because of the huge university and the high number of scientific institutes and facilities.

All in all I am really glad that I have the possibility to make my PhD at KEK and that I can enjoy the life in Japan.

（Phan） My impression of Tsukuba City is of a collection of research organizations and university.KEK and Tsukuba university are example.

We plan to continue this kind of efforts and inform everyone on this web page .

I will be seeing you again .
