Organizing committee


Two days of guided excursions will interleave five days of lectures. The expense is included in the registration fee. We may visit the following sites:


Participants should apply for L visa via their local Chinese embassy or consulate by providing their ordinary passport, visa application form, and other required documents. Information can be found online. For US students, please check this page.

Please register as early as possible so that we can send you necessary documents for your visa application. There is no need to book the flight in advance since our invitation letter would work for visa application as well.


Breakfast will be provided by hotel. We highly encourage you to book lunch box and dinner provided by the local organizing committee to have save, convenient and delicious food. Tickets can be purchased on site one day before the school. Please indicate your food preference in our registration form so that we can prepare accordingly. We can provide information for your own food adventures on excursion days. It would be wise to have some local students in your adventure team.


KeHua Hotel

We will be staying in the KeHuaYuan Hotel right on SCU campus from July 11 to 18. Its address is

No. 141,
Ke-Hua North Road,
Wuhou District,
Chengdu, China

There is no need to make your own reservation as long as you register online. Students are highly encouraged to share rooms. Foreign students will be mixed with Chinese students to increase culture exchange opportunities.

Lecturers will stay in the same hotel to maximize the chance for students to discuss with them.


Transportation between SCU and CJPL will be provided by local organizers, which is not included in the registration fee.

Some local students may meet you in Chengdu airport if you need help to find your way to the hotel. If that is the case, please email the organizer your flight information as soon as you have it.

Financial assistance

PIRE GEMADARC provides some limited amount of travel support for graduate students. However, to be elegible to receive the support, one has to register before April 30, 2018.

For students at USD, please check The link also include some general information on finding financial assistance.

Culture and activities

In addition to two days of excursions, we offer you


The registration fee is $160 US dollars for students outside of China, and 1,000 RMB for Chinese students. It is used to cover the following cost:

  • coffee, tea, and snacks in between lectures
  • a banquet and a culture show during the banquet
  • two-days of excursion
  • a T-shirt and some stationaries with PIRE-GEMADARC logos

It can be paid on site on July 11 by cash. The online payment option will be available soon.

No deadline is set for registration. However, if you want to compete for the limited financial suport, please register before April. 30. Please fill this registration form (outside of China) at your earliest convenience so that

  1. We can have a rather accurate head counts in an early stage for better preparation (Registration fee is not required for filling the form).
  2. We can provide necessary documents for participants outside of China to start their visa application processes.

Please be cautious about purchasing air tickets before obtaining a Chinese visa. A round trip ticket from US to China in July at this moment costs about $1,200, and will be quickly approaching $1,500.

Please note that the registration process and fee are NOT waived for lecturers. They need to fill the form and pay the registration fee as well. However, lecturers from outside the PIRE-GEMADARC collaboration may receive lecturing fees as compensation.


Mentoring and Exchange

How it works

A more senior person hosts a more junior person and provides opportunity and mentoring:

Senior faculty/staff could offer projects for junior faculty/staff

  • for planning an experiment
  • drafting an MoU
  • budgeting a project
  • writing a grant application
  • develop a course

The project should help the seniors as they would delegate some work, and help the juniors as they gain experience. There could be projects where no travel is required.

Any faculty, but especially junior faculty/postdocs , could offer projects for graduate students

  • measurement campaigns
  • design of test setups
  • building of test setups
  • prepare a lecture
  • write a paper

The junior faculty gain experience in guiding people, planing and mentoring. The graduate students learn something in a new research environment. The length of the exchange should be between 3 and 9 months.

Graduate students could offer projects for under-graduate students. [the RISE model]

  • do some test measurements
  • help with building something
  • help with some programming
  • build a little something needed for the graduate work

The graduate students gain experience in guiding people, planing and mentoring. The under-graduate students learn something in a research environment. The lengths of the exchange should be between 8 and 15 weeks.

Under-graduate students [with help from above] could offer projects for high-school students. It is very good for the students to think about how to teach 15 to 18 years old.



Researchers at MPI welcome visitors at all levels, as long as they are more than 18 years old and have valid papers. The best experience is normally obtained in a one-on-one situation.

They can provide required invitation letters and directing people how to register [which is required for people working there]. Health insurance is required! It can be purchased there, if it cannot be proven to exist. Liability insurance is also required. It can be provided together with a small contract [below the taxable limit].


Undergraduate program

PIRE-GEMADRAC offers an opportunity to obtain research experience this summer in China. The program lasts 10 weeks with 6 weeks in China. The scholarship is $10,500 in total including $5,000 stipend and $5,500 travel expenses. The flier of the program for this year can be found here. The application deadline is Feb. 20, 2018.

Graduate program

International exchange program

PIRE-GEMADARC also provides international graduate exchange programs involving worldwide best facilities and prestigious institutions: MPI in Germany, Tsinghua University in China, Academic Institute of Physics in Taiwan, and Queen’s University in Canada. Scholarship receivers are expected to spend 6-10 weeks every year on Ge-based low-energy neutrino physics, dark matter searches, and neutrinoless double-beta decay experiments.

Travel support

PIRE-GEMADARC offers travel award up to $3,000 for graduate students to participate
